Windows 7 Hangs Indefinetely After Loading Null.sys Driver?
Mar 6, 2011
My windows 7 pc locked up so did a hard boot. Not it is hanging on the "starting windows" screen. In safe mode same thing, but can see the last driver listed before hanging is null.sys. I see the hard drive light continuing to flash after waiting 30 or so minutes no change.I've tried regular boot, last known good boot, safe mode, startup repair... they all hang.Any suggestions on getting this pc booted or what the issue is? Not sure if hard drive ran out of space due to some operation or maybe a virus or something else.
Computer Stats: 2009 Macbook Pro running Windows 7 Ultimate x32 via boot camp, all drivers up to date as of last night, no non-factory parts or tampering with any system files. Issue: Around a month ago, I noticed my laptop freeze up whenever I left it unattended for more than half an hour. Sometimes it would lag for 30 seconds or so and then be fine, sometimes I would have to reboot entirely. This happened again two days ago and upon rebooting it became stuck during the animation at the "windows loading" screen. I restarted and used F8 to pull up the advanced boot menu, chose "system repair", and it went through two loading screens before presenting a black screen of death that never seems to change. Booting in safe mode works, which I've used to scour the internet for fixes and ways to get incredibly drunk. Attempted Fixes: A full system virus scan (duration: 13 hours) with Kaspersky, Malware Bytes, and Panda. Nothing was returned save a few false-positives from torrents (only trusted trackers, nothing dodgy file-wise). Used the "repair my computer" option at F8'd start-up multiple times to no avail. Used "sfc/scannow" twice, which downloaded some windows updates but didn't fix anything. Yelled really loudly at computer and raised my hand as if to smack it, intimidating it into submission but not fixing core issue.
Here is the result of my bootlog, but before that I'll note that it hangs on "Loaded driver SystemRootsystem32DRIVERSCLASSPNP.SYS" for about thirty seconds when loading in safe mode. I thought that might have been the root and downloaded another copy of classpnp.sys, but again it didn't change anything:
Quote: Loaded driver SystemRootsystem32DRIVERSCLASSPNP.SYS Did not load driver @hal.inf,%acpiapic.devicedesc%;ACPI x86-based PC Did not load driver @battery.inf,%*compbatt.devicedesc%;Microsoft Composite Battery Did not load driver @battery.inf,%*compbatt.devicedesc%;Microsoft Composite Battery
[Code].....
edit: I made a system recovery disk and attempted to use both its automatic fix feature and its "detect memory problems" feature. Both came back completely fine. Nothing has changed.
edit: Startup Repair has verified that the root cause is a driver. However, I've no idea which one. Surely that's contained somewhere in the bootlog.
During a recent windows update my pc froze, (mid-update) and I restarted my machine. Now windows gets stuck at the black" Loading operating system..."screen. After a long wait it will eventually display boot from cd/. When I boot from my windows dvd my os is not shown in system recovery. I Have also tried running start up repair from recovery with no luck.
I'm using windows 7 home prem 64bit. This problem just happened today. I sign on with my password and the system says welcome, but won't actually login. It just hangs there. I used Avast to do a complete scan, but it didn't come up with anything. I used MS security essential it found a bunch of Java exploits and trojan downloader and I deleted them. But the problem is still there.
I'm new here.I couldnt find any solution for my problem anywhere and i thought i can find it here.
I have Windows 7 Ultimate 32 Bit and im trying to install it for about 6 months. I installed it once but after one week,os is gone and stuck at classpnp.sys
Here are the steps i followed when trying to install; Selected Boot Menu > CD/DVD
Seen windows is loading files. Seen Starting windows but its gone before the 4 colored windows logo comes.
And endless black screen. I also tried to boot from dvd in safe mode.It hangs at disk.sys I checked rams. I have 1 gb x 2 rams.There is blue and brown sockets for rams on my motherboard.
Both of rams connected to blue ones.When i disconnect one of them pc opens but same issue. When i disconnect one of them and connect it to brown socket pc didnt opened.
i recently purchased a new toshiba laptop with windows 7 64bit installed, which worked pretty well until i ran into a random crash a few days ago. i'm not sure why it happened, but at the time, i was running a Internet video and then i got a post on google talk. at that point, the computer froze on the sound and i wasn't able to use the mouse anymore. it acted like a stop error, even though no blue screen popped up or anything. it seems like it freezes like this when i leave the computer on for a long period of time or something. it's happened around three times, once with the google talk sound, and twice with the skype sound, and all three times Internet was opened.
anyway, ever since that initial crash, i've had a hard time starting up the computer. the first time, i attempted to run the task manager and click the "show processes from all users" button, however after clicking the button, the computer seems to hang at loading consent.exe, and the cpu was around 4% or so. i was also trying to load google chrome, but it wouldn't load either. after waiting about 5 minutes, i pressed ctrl-alt-delete, which then i got an error that the window couldn't load.the second time i tried running the task manager, i noticed that the networking and sharing center wouldn't work at all. i could run programs (that weren't internet browsers), as well as the control panel... but i couldn't open the networking and sharing window from either the control panel or the icon on the taskbar. consent.exe was hanging in this instance as well.
after those two times, i was able to get the computer working again and didn't have too many problems as long as the computer was on. ran into the problem again after successfully shutting down windows one night, then trying to turn it back on the next day. however, this was even more odd because explorer.exe crashed on its own, but i hadn't done anything since i turned the computer on. i also couldn't get the task manager open for some reason.today, after leaving the computer off since last night, i tried turning on the computer again, and once again the computer hanged on trying to load google chrome and the task manager. this time, the task manager wouldn't load, but the icon would appear in the taskbar (frozen. can't right click it or anything.) and skype was working. i made a comment on google talk, but that froze after i got a response.i was able to hit the shut down button in that instance, but after waiting 8 minutes, the windows logoff screen wouldn't show up, so i just shut it down and turned it on again.
the thing i would use it for first is with my personal ICS internet connection sharing adapter which i use to share an android phone unlimited internet plan usb tethered into a NAT box, or an internet share host if you will.i use my physical adapter as the share host, as the selected share adapter when the internet broadband adapter (the phone USB in this case) is set to use ICS. this sets to physical adapter to 192.168.137.1. 255.255.255.0 with empty dns and gateway. this is proper for ICS setup. now behind the lines, any adapter than can connect to 192.168.137.1 can get internet access. that part we know. then you take a router and connect it into this subnet by using 192.168.137.2 as the routers address. then you generally either control it as a NAT, or you set it up as an access point.you need to turn off the routers dhcp, then you let the ICS adapter control dhcp, which is default.if you turn on your wireless access, any computer on the subnet will grab their ip from the dhcp on the ICS 192.168.137.1 adpater.this is what i have been using for some time now as my favorite setup. a while back after searching for better ways to be able to leave all client machine (such as my laptop, or any other pc throughout the place on the LAN) ip set to auto, and dns set to auto(default) so that NO tweaking would be necessary on any client to get access,the client would send dhcp request across the WLAN, the router would pass it to the ICS device, the host would create the response and send it back through the router and issue a new ip, and dns, the client would be fully connected through that route.i have this set up just fine, and have been using it for some time. now im a picky windows user and like things to be perfect, but you might NOT guess that it bothers the hell out of me when go into 'network and sharing center' and i have to stare at a connection that refuses to act normal, is listed as "Unidentified Network", and when clicked on will NOT let you edit the name, or the icon. I want that thing to say "Belkin Router", or "Internet Gateway" or something of the Sort. And i want that ugly public bench off the screen. I would pick the gateway icon with the router and two piped clients as the image, or something besides that bench, lol.
Once i have that, i can look at my network structure as comprehensible, and it would polish off the process. I know some of you probably know the solution right off the bat. But it also led me to a thought. first of all, please submit any ideas that you have i would like some opions on this one, as to your personal solutions, Im always open to better ones, but i also always love another tool in the arsenal.
But on the other hand it got me thinking, specifically about the topic of this post, the null adpater.For fun, and to further organize the system and open up a bit more headroom to the default internal network adapter on the internet connection share host machine, it would be nice where insted of having to dedicate that DHCP to the physical internal adpater, it would be nice to push that off to a NULL or virtual adapter, so that the ICS adpater could either USE the NULL virtual adapter instead for its host dhcp and connection share adapter, OR it could use the standard physical adpater but push off the dhcp functions to the virtual one so that the physical one can have a little more flexibility on addressing by either setting to static, or better yet set to auto where if will get its ip from the virtual one.
HOW WOULD I set up a NEW NULL virtual adapter in the host pc that will act like a normal network adapter that can communicate on the subnet to the physical adapter with tcp/ip, and where this new virtual adapter will be selectable for ICS services, as found in the sharing tab of the newtork properties on a standard network propertied dialog box.What i want to do with the host is connect the internet device into the host machine via the usb phone adapter(broadband adapter), that network adapter will create itself on the host machine as drivers are installed, then i go to the properties of that phone adapter "broadband adapter", then to the 'properties','sharing tab', turn on ICS sharing, (if it asks you, then select an adpater [(select the NEW NULL VIRTUAL ADAPTER as the sharing host, leave DHCP enabled[default])].
Now as for the hosts physical adapter(not the broadband phone adater, but the onboard internal NIC [or wireless network adapter]) on the host machine would be alleviated from ICS duties, and will be ready for duty to connect how we see fit. The null virtual adapter has taken over the duties of the ICS, which will reduce any futher confusion, especially for those casual users who when setting up their client adpater like to use the host machine as a roadmap or model. after all, their host machine is probably not much of a host, but just another client who ended up being in the same room as the telephone, or other internet access point happened to be plugged in, so not is it only a host, but its a slave too, because it was used because of location, not because of function. So lets realize that its more of a client than host, so why should be have to dedicate it to host or server status just because we needed to connect the broadband adapter into it, why cant we just make sure the physical NIC card can be left alone when setting up ICS and just settle with re-naming the hosts physical adapter to something a bit more comprehensible, and stop there and let the auto ip take care of the rest? This is not currently posssibly with current ICS setup, because renaming and icon changing are blocked out. So normally, as a client, we use ip auto, this is easier. So this machine can just become another client once the machine is set up to use this null virtual adapter used as the ICS host adapter(192.168.137.1).Now when a less-experienced or memory-compromised user comes to mess with the network settings, it will be readily obvious whats going on here, and easy to adjust without messing up any settings. If this user uses the host machine network adapter as a model or roadmap for the rest of the clients setup, then the setup is identical and clear. The adpater will normally be set up as IP Auto, setup completed, not so hard. They will never need to question the setup. That is just one benefit. Another benefit is the fact that the actual ip address of this host physical network adapter can now be set to whatever needed, if necessary. maybe its a internet server. the host needs to be static if anything other than netbios names are being used. So you can set the ip to the desired host address, and now access this host machines services faithfully and dedicated.and low and behold one of my reasons as being a picky windows user, i want that ugly public bench off there, so i can change my physical adapter icon now to a more suitable image, and then rename it to 'ICS host', or 'Closet Server' or something of the sort. Well, atleast we can get the physical address acting more like a client which is alot easier to maintain the properties of than a server adapter. This will reduce the maintenance to just the setup, as opposed to ongoing, everytime the properties are adjusted.
In the end we can now treat this physical adapter on the host machine the same as any other client machine adapter, therefore if ip is set to auto, then it will automatically register itself onto the Virtual adapter that we created and get an ip on the 192.168.137.0 subnet. Now since dhcp will issue out a limited set of adddresses some where in the middle of the ranges of the 192.168.137.0/255.255.2550 subnet, it will keep some key unused ips available.With these extra IP's you set your router or access point LAN static ip address as either 192.168.137.2, or 192.168.137.254, this is your Gateway address. on the router/accespoint settings, you must turn off the DHCP services. If router or access point equipped with internet connection or wan settings, leave them set to AUTO or DYNAMIC. whoa, that was easy. Your router access-point will now pass all dhcp requests to the ICS adpater (this is default behaviour for ICS adpater to look for dhcp requests), and the ICS adapter will lease out a new unused cleaned washed ip back, and the new client will get a new leased ip. This will finish off the router or access-point setup with full internet ervice.
How would i create a virtual network adapter that i can give this kind of control to (ICS services) and are there any opinions on further slimming this process;? Is there a way to just rename the default ICS adapter that we know now (as created normally with the physical adapter as its host, as opposed to the new VIRTUAL adapter idea) by editing something in the registry? Is there a way to change icon when the default method wont allow you to?And i think i have tried this before cant remember if it works or not, but has anybody been able to get ICS adapter to serve dhcp still and connection share when the ip address was manually set to anything other than 192.168.137.1?
I use Internet Explorer, Firefox and Chrome. Firefox is filled with privacy tools including Privoxy, Ghostery and Disconnect. My other browsers do no have anything. I use Windows firewall, Avast Free and Full version of Malwarebytes with malicious web-site blocking turned off. I also use Spyware Blaster. I use Windows 7. I am behind Cisco router.
Problem: When I use facebook.com either https or http, after a certain period of times or page visits, the facebook stops loading and "hangs" on a page not going back or forward. I either have to wait, or close it and open another browser. This has been going on for quite some time. I tried clearing everything with CCleaner, flushed DNS, Etc. When I ping, I get all 4 responses.
I have a freshly built computer. All new internal parts (HD, DVD drive, MoBo, video card, processor, PSU, RAM and case). Here is a list of all the parts that are in it:Newegg.com - Once You Know, You NeweggI also have a fresh copy of Windows 7 OEM.All parts are plugged in properly, and bios set up correctly (as far as I can tell). The only bios that aren't at default that I can remember off the top of my head was that I disabled the floppy section (don't have one), I raised the clock speed of my CPU to 2.8 (up from 2.66), and I enabled my CPU to raise 9-11% capacity under heavy loads.verything saved properly, and my CPU runs at roughly 35 degrees C. Not nearly as cool as my old rig but not that bad. The default settings had it running half a degree cooler.
Opened up the 7 case, popped it in, booted from CD-ROM, and a black screen comes up and says "Windows is loading files..." A bar fills up really fast, and after it finishes it resets and starts filling up again, much slower. Once this bar fills up however, the computer hangs and sits there. I've let it sit for over 10 minutes with no change. The only notable thing that happens is about 30 seconds after it fills the bar the DVD drive has some activity, and then it goes silent for the rest of the time.
I have Windows 7 x64 Pro. Well I have been going fine with my Sony DCR -PD170 firewired to my PC. I plug it in and it pops up asking me if I want to the whole or part of the video and so on. Then I let Windows Update load the SP1 service pack and it will not load. So I go to my laptop that is Windows 7 HP x64 that also went to SP1 and it works! So I look at its drivers and they are "msdv.sys" & "ksthunk.sys". I try copying them to the same local in the desktop and no good. I try other folders like windows, Sys32/drivers/ and so on but to no avail. I even direct it to them on my desktop.
Fresh install loading Windows 7 it asks for mass storage device driver with CD for motherboard open on Z77-DS3H and drivers available where is mass storage?
My computer just started getting the BSOD error. For the pst week my mouse and keyboard just froze but not the whole computer. the only thing I noticed before it restarted was "USB Driver" (Mouse Hangs randomly).
Every time I shut down my computer, not restart, when I turn it back on my Nvidia drivers don't load and I have to reinstall them. Restarting the computer works fine, it's only after a full shutdown. I tried reformatting just to see if that would solve the problem, it didn't.
System: Intel i7-920 @ 3.8 GHz MSI Big Bang XPower Elpida 6GB (6x1) DDR3 573 MHZ MSI GTX 560 Ti (x2) Samsung 1TB, WD 1TB MSI Quantum Wave soundcard, Asus wireless card Windows 7 Ultimate x64 Corsair AX850
So this is not the first box I've built but it is the first time I have not been able to boot easily for so long. The symptoms are that it hangs at the windows logo on the start screen, most times. If I do a safe boot, then sometimes it will boot successfully afterwards.
I can play Call of Duty 4: Modern Warfare, watch movies but opening a picture would cause a BSOD. I fixed the last symptom by reseating the card and installing the latest driver (195.62) while only the vga monitor is connected. It still hangs at the start screen though on a cold boot.
I have used the Windows 7 mem test to confirm it's not memory. I have then done a boot log (ntbtlog.txt) and I can see the following lines repeated as it tries and retries to load drivers:
Did not load driver @hal.inf,%acpi_amd64.devicedesc%;ACPI x64-based PC
Did not load driver @cpu.inf,%intelppm.devicedesc%;Intel Processor
... (more of the previous line)
Did not load driver @oem6.inf,%nvidia_dev.05e3.01%;NVIDIA GeForce GTX 285
This happened on the driver that came with the device too. I can tried repair installs and clean installs of my OS. I tried deleting the driver altogether and then letting windows load a driver for it and same result. Aside from sending the card into the manufacturer for testing, are there any ideas out there on what i can do?
Sadly, I am actually enjoying the challenge. Mostly because on the rare occasion I can boot normally and use my pc normally and leave it on for easy's sake.
I'm at my wits end now though, After several attempts at installing Win 7 RC (64bit) I realised it wouldn't let me becasue I hadn't added the latest drivers for my motherboard. Now it appears to have installed but whenever windows starts, it reboots at the point where the first 'red dot' appears (the four colours swirl in to make the window).
I ran in safe mode and it appears to reboot whenever it gets as far as 'system32/drivers/disk.sys'
I have installed to three different HDD, both IDE and SATA. All clean before the start. I've used an IDE DVD drive and a USB external, and my BIOS is totally up to date. I've now striped the PC of everything none essential.
The latest drivers for the motherboard are the Vista 64bit variety because there are no windows 7 drivers (that I could see).
P.S. I also obtained a copy of the 90day release version of 64bit Ultimate, which a friend has successfully installed on his Vista laptop. I've tried installing this with all the same configs and same problem every time.
One particular site that is not loading at all, on any browsers on my computer is [URL]. There are many more that fail to load as well. I did test these sites on my iPhone with no problems though. There are a handful of other sites that do open but do not load properly [missing images, ect.] I also thought that it might be malware but I installed & scanned my computer with four different programs which did not solve the problem. I'm guessing that it still may be some problem on the software side with settings but I can't seem to figure out where to look. BTW, I've been using Microsoft Security Essentials as my antivirus program for the past couple of days now. Prior to that I was using Avira but it seemed to be giving me problems so I uninstalled it and installed the Microsoft app.
Windows 7 Home Premium x64 will hang after the "Starting Windows" logo, showing only a black screen, forcing me to hold down the power button.Windows will boot in safe mode and will boot if I disable my video card from Device Manager.I have run hard drive and memory diagnostics without any errors showing up.I did not change anything before the problem began occuring.I've already tried restoring to the initial system image from Lenovo OneKey Recovery (I'm using an IdeaPad Y560) and using the Windows System Restore, as well as updating drivers and BIOS.Attached are my event logs in administrative view from today (The problem has been occuring for a week or two, however, I don't have access to logs from that time), in which I reinstall my drivers and attempt to install a download manager in safe mode among other things.
I just installed a new ssd (X-25m) on a clients computer along with Windows 7 64bit and 8GB of RAM. The computer hangs for anywhere from 10 seconds to 30 seconds+ and sometimes just freezes up all together until I restart. Sometimes, it freezes icons and I can still use the mouse, and can double click to start a program, but it won't start up until it unfreezes, then everything I've opened suddenly opens all at once. Other times, even the mouse is frozen, and I have to wait 30s to a minute before I get it back.
Things I've tried- all Windows Updates, and updated all chipset drivers for the mobo (MSI P6N SLI Platinum)
New hard drive, new install of windows 7. Machine freezes without warning, Sometimes after 2 hours, sometimes after 2 days. When frozen, unable to CTRL ALT DLT or Start / shut down.How to diagnose root cause and solution?
I am trying to upgrade from Vista Home Premium to Win 7 Ultimate using a DVD bought at retail. The upgrade process hangs while Gathering programs and settings, always at the 86% mark. Yesterday it hung at 6:00 PM and I let it run overnight -- at 9:00 AM next day it was still hung. No error message, no shutdown, just sitting there waiting.Following suggestions from various sources I have tried working from an empty start folder in Vista, and from a clean boot in Vista. Neither made any difference. I have turned off antivirus and taken down the firewall. My system is approved for upgrade by MS. I have tried starting the upgrade program from Vista safe mode and by booting from the DVD, but was not allowed to continue. I have done everything suggested by MS as a prelude to upgrading.My computer is a Dell Inspiron 530.
Windows 7 Professional 64bit When I try to perform a restart, the computer goes into oblivion. Drive light flickers a bit but I've let it rest over an hour and it didn't restart. Have to press the reset button. Otherwise everything seems OK. I've run deep scans with Malwarebytes and Kaspersky and no warnings?

It hangs on start up; it gets past the Bios but stays at the Windows Logo and says "Loading Windows" until I am forced to shut down. Here are my specs:
EVGA 780i mobo 3.0ghz intel duo-core processor 4 gigs of DDR2 RAM 1 TB seagate HDD 1 gig of video (Gforce 9800GT 512mb SLI)
So my computer was working perfectly fine until this happened. However, this has happened before! This same exact problem happened before, so I figured it was the hard drive so I got a new one(the one I have now).Fine, it worked for about 1 month. Then this happened... again. I do not know what the problem is. Like I said in the description if my computer does get past the windows logo and I log on, after about 10 minutes of running I freeze and have to force shut down. Then I am stuck back at the Windows Logo... I have also tried to insert the Windows CD itself and try to repair windows, but even then it still won't get past the windows logo.
A friend asked me to take a look at her laptop. It's a Toshiba Satellite L775 with Windows 7 Home Premium. The computer starts fine until the green progress bar finishes loading. After that, a cursor appears and can be moved, but nothing else loads. F2 loads BIOS during startup, F12 loads a boot menu, and every other F key (other than F8) loads an OS selection screen. F8 does nothing. I've also tried booting from a restoration disc. The pixelized progress bar loads (slowly, as is usual when booting from a disc) but then the normal boot process continues with the same problem as before. I can't even get into Safe Mode to try and troubleshoot anything.
I have a problem with my laptop (A Sony Vaio VPCEB4J0E) Basically, whenever I tell it to shut down, it doesn't actually do so and only closes Windows explorer so I'm left looking at my desktop whilst nothing happens.
This is something annoying and surprising- I thought Microsoft fixed these issues. What happens is when ever I start a media player (Power DVD, My TV Tuner, WMC or MC) the computer freezes for a moment (about 20 seconds) and then becomes normal. Same happens when I exit the media program.
Systems hangs after seemingly OK boot. Logged in as user but no desktop icons. Rebooted in Safe Mode - seemed OK.Looked @ Event Log. Errors
[code]...
A timeout (30000 milliseconds) was reached while waiting for a transaction response from the Dnscache serviceRestarted in Normal Mode. Booted fine and logged in OK. Still get the 7003 errors but system works OK.Has only recently started to happen but I have had to remove a Trojan Virus. All virus checking is OK but I suspect something got damaged.
I successfully transferred my WIN 7 and Programs (they are on an OCZ SATA SSD) to a new motherboard and CPU. Until here no problem, the OS started perfectly, went online and activated my copy of Windows 7. Then I shut down and connected my second HD, a small 320 GB Scorpio where I save all my personal files. Reboot and Windows 7 after loading, freezes. Had to reset and boot in save mode but no information about the problem. devices are OK, the disk is seen from the system with its correct letter but when I boot normally it still freezes the OS. As soon as I disconnect the SATA HD's cable, Windows 7 boot perfectly. On UEFI Bios all the 6 SATA channels are enabled, I also tried to change connectors but the problem is still there. If additional details are needed
I have spent all day failing to install Windows 7 on my system. The only thing I have done since the last successful install is to create a RAID 5 using 3 259GB HDDS. The system worked when the 3 HDDs were not RAIDed, but now installation hangs after the second restart. All I get is the black screen with the mouse arrow; nothing else. I tried the cmpmgmtloader solution and disabled the network adaptor and usb controller which were showing as having problems. I even tried un-RAIDing the HDDs and going back to the original state and still it hangs.
2. Clean start and shutdown in Win XP - implies software issue not hardware
3. I haven't tried Windows 7 32bit yet.
Here's some details of my investigation so far:- All of these tests failed to solve the problem.
Unplugged all devices. Fresh install Added manufacturer base drivers. Windows updates applied Safe mode Windows clean start only one memory slot filled (both slots)
In desperation I've created a trace file (using this article Gathering a Startup, Shutdown, Sleep, Hibernate, or Reboot Trace - Windows 7 Forums)
i've recently done a fresh install inc SP1 of win 7Pro x64 and now the pc almost constantly hangs on shutdown.everythings up to date driver wise etc.I was aware of this problem on my older quadcore machine but had it very infrequently, this happens almost constantly on my new one.Found a hotfix which i tried to install but had a warning say that "not applicable to my computer", i then realised that the problem was addressed in SP1.
