When using Windows 7, it randomly goes to the lock screen during an active session. This has been the case on multiple computers running Windows 7. Immediateness proceeding the lockout the screen flashes black and than shows the login screen. All of the external hardware is the same, one computer was a desktop, one is a laptop.
I've been using computers since Win 3.0, but have recently built my own computer for the first time. Generally, everything works great right up until the point it doesn't.Sometimes my PC will randomly just "lock up". The screen freezes, the keyboard is completely unresponsive (including ctrl-alt-del), the mouse cursor is the spinning circle. The only way out is to hit the RESET button.It seems fairly random, and has happened while I was using iTunes, Outlook, or other programs.The one constant is that every time it happens, I can see that the HDD activity light is *solid*. It's not flickering / blinking like with normal HDD access, just solid. I don't know whether there is something truly being accessed, or whether the solid light is just a red herring.
Also, I don't know if the system is actually frozen, or whether there's something hogging the system to the extent it's so slow that it appears frozen. It's a pretty beefy system, so whatever it is would have to be really doing a number. I've only ever waited like 2 minutes before giving up.Given that every time it happens the HDD light goes solid, I have to suspect it's something with the hard drive subsystem, but I don't know how to begin troubleshooting whether it's a mobo SATA port issue, an Intel RST driver issue, a hard drive issue, a cable issue, or maybe it's not the hard drive at all!Here's some details (see more in my Systems Spec)Recently purchased DZ68BC mobo Prior to Windows 7 installed, verified mobo BIOS default was AHCI Installed Windows 7 64-bit Home Premium Win 7 appears to use AHCI After installing Windows, ran Intel utility to update/install all drivers, including Rapid Storage Technology drivers (did *not* update mobo BIOS) I am NOT running any RAID.Again, everything seems to work really nicely, right up until the point it decides to instantly freeze It's hard to troubleshoot because it's so random, I don't know when to expect it, and after it happens I can't bring up any tools (i.e. Resource Manager) to see what's going on.
I've been getting random lockups for quite some time however here is the kicker,it ONLY happens with more than 4GB of RAM installed...anything less than 4GB I am perfectly fine but anything more my computer locks up totally randomly.Random bits of information: Tested all of my RAM sticks individually and in any combination I can think of,as long as the total is nothing more than 4GB I'm fine and dandy but soon as I hit 6,8,10(Due to what sticks I have I can only go up in multiples of 2GB) I get random lockups.Lockups can happen on desktop when I'm afk and the computer is completely idle,after 2 hours of intensive gaming killing splicers in Bioshock 2 or just while I'm transcoding a movie on the fly(This actually seems to be relatively safe,does not happen often)On the lockup whatever sound that was playing repeats(The last 0.2 seconds of it or something) so it sounds like BZZZZTTTTTT no matter whatNew motherboard,new PSU and hard drives passed a chkdisk recently(Albeit with some grumbling from them about bad sectors)SFC scan completed,no problems to report with my file integrity.PSU has plenty of power for the systemJust recently installed SP1(After the problem started) in an attempt to fix it,to no avail by the looks of the recent lockup and now I have no updates pending so windows is fully updated.
Obviously checkSUR ran with no problems before installing SP1Booting into an Ubuntu liveCD and running random stressy things for the computer does not produce the same effects,it runs perfectly fine.Computer temp is high but within an acceptable range most of the timeOnce it crashes/locks up once it sometimes does the same on boot again and again till I just leave the thing alone for an hour or two and try booting it up againEvent Viewer just shows this for each event when it locks up and I'm forced to reboot it manually:[CODE]

Prior to building the New PC I had no issues at all. I got the New Motherboard, CPU and RAM. Built the computer and started having the issue that my Computer would Lock Up randomly, it seemed to be when I was playing a game and having other stuff going on my 2nd monitor. Just Lock up, no BSOD and nothing in the event logs. Have to push and hold power to turn off and then reboot.
I thought it was the Motherboard as I don't tend to use anything but Asus, so I sent back the ASRock motherboard and purchased the Asus Rampage IV Extreme. Reinstalled Windows with the Asus Motherboard still had the lock up issue. Next I got new RAM - I purchased the G.Skill Sniper series 1866 Ram, thought that was going to fix the issue BUT Still got a hard lock up. It seems to happen when I am playing a game and have other things going - It seemed to happen when I played WoW and Diablo 3 which were actually installed on my 2nd harddrive ( Velociraptor).
I moved my WoW folder to my Kingston and removed the Velociraptor -- Still Locked up. Only thing at this point I have not tried swapping are the PSU, the Video Card and the Harddrives. Because those all seemed to work fine in my old system I didn't think those would be the culprit. I have no tried changing out the CPU but not sure if that would be the cause as the computer seems to run fine with out locking up if I'm not playing a game and other stuff. Also - Temperatures are not the issue as I've been monitoring them all and the CPU is usually at 30c-34c and the GPU runs around 60c-65c.
I m having problem accessing a specific software while log in to my PC under Active Directory domain user. This software works file while work as administrator but show run time error 75 , path/file access error.
I have encounter a problem where my "Active directory users and computer" function suddenly unable to connect to my remote server. I have run a nslookup and below are the reply
I confirm it is not the next work issue because in the same network there is few more PC running windows 7 and XP, they don't have the problem as I mention. I also have a virtual XP running in the notebook that I am using, So I try to install the adminpak and run the Active directory users and computer and what a surprise it work. I have try to reformat the notebook and the problem still occur after I use it...
I tired of reformatting. Update on the troubleshooting of the problem I am encountering, I find out that the windows 7 that I am running is not able to resolve any PC name on my network. I am mentioning this because went I am using the virtual machine install in the notebook (Win XP) to remote desktop to other PC using the desktop name it is working fine.
Looks like something is holding it up, I reinstalled the drivers but I think it might be a software issue where a program is not exiting properly and holding the system down.Every once in a while the system will shut down but most of the time it hangs on shut down, times out and errors out.
I have had this computer up and running with the same LEGIT copy of windows 7 64 bit ultimate since Christmas time this year. All of a sudden the other day it just started locking up all the time. It runs Ubuntu well that is installed on another hard drive. It also boots into safe mode fine. I ran antivirus and malware scans that turned up nothing. I then checked the hard drive for disk errors and it came back fine after multiple checks. I had went into msconfig and made it restart with a clean boot still the same thing. At this point I gave up and had backed up everything and reformatted the drive and reinstalled the same copy of Windows 7 and now have the same thing. I have done multiple hard drive checks, memory tests, I have taken out one of my graphics cards and made it not sli.
I have a dell XPS l{ess then 1 year old} quad core Intel processor plenty of memory and all. I am trying to upgrade to win 7. The compability manager says I am fine for the upgrade. During the installation the computer seems to be locked up about 3 quarters of the way through. The progress bar is simply stopped. I started the install about 11:00pm and it's now 5:25am. Should it take this long? This is the 2nd time I have tried this and the same thing has happened both times. The only way to abort it to restart the machine and then of course I will have lost all the vista files and updates.
I am running Windows 7 64 bit with the latest updates installed.
Today i switched on my computer, logged in and after a few seconds the computer locks up. I am unable to open Task Manager or any other program. I am still able to use the mouse, but nothing opens. I tried Safe Mode and it works fine. I am in safe mode as i am typing this.
In safe mode I am running a scan with Spybot Search and Destroy. It has found nothing.
I recently had a PSU failure and replaced with a new unit. System now powers up.
However Windows is now randomly locking up. No BSOD, no warning, it just locks and stops responding. No screen corruption either. The only solution is to power off. It never once did this prior to the PSU failure.
The lockups happen randomly, maybe after 20 mins, maybe an hour and have occurred when:
Internet browsing Running a large Backup Installing the new SP1
There is nothing in the event logs that suggests anything happening prior to the lock up. There are no heat issues.
To try to isolate the problem, I have: Run Memtest86 for hours with no problems and also the Windows memory test, all fine.
Run Prime95 for a while again with no problems. I am gonna do some more tests later in Prime to check cache specifically. Reinstalled Windows on different a Hard Disk and still get exactly the same problem.
I am now coming to the conclusion that the PSU failure may have caused some sort of damage either to the motherboard or processor. I am going to return the new PSU to the supplier and get a replacement sent out just in case the new PSU is at fault.
I was working on my computer security permission, and now I ended up with zero permission on most folder. I could not access control panel as it pop up "Restrictions- This operation has been cancelled due to restrictions in effect on this computer. Pls contact your system administrator".
I wiped it clean from issues of locking up. I have done 3 fresh installs of Windows 7 Ultimate 64 bit retail using all up to date drivers and everything, I have tried with CPU overclocked and normal clock. When I boot up she runs fine and then when I start listening to music off of my backup drive or browse the internet she will lock up at random, and by lock up I mean it is like im looking at a picture of my screen frozen with no responsiveness whatsoever not even the mouse moving no HDD activity ... nothing! So Ive installed the OS 3 TIMES fresh install new partitions format etc. It does it every time after I let windows update do its thing or just listen to music off the backup drive.pecs are:Windows 7 Ultimate x64 RetailBiostar A780XA2-03 Socket AM2+ MotherboardAMD Athlon 64 X2 3800 CPU4GB Ram - I have swapped sticks that I have had - ( 4 1gb sticks 533mhz)
For the last couple of nights, there has been an update to apply when I log off. In both cases, the update seemed to hang and I left the computer switched on overnight with the monitor switched off.On the first occasion it was still hung in the morning so I reset the computer. All seemed to be OK during the day but when I came to close down there was an update to apply. I guess it was the same one. It hung again and I left the computer overnight again. This time it had switched off but when I switched it on again it came up with a temporary profile.A message appeared telling me to look in the event viewer but that is a waste of time as there are several hundred million entries which don't mean anything to me.Where do I go from here? I guess I can do a system restore but that is likely to lead me back here after a day or two as the system tries to keep itself up to date.
I cant get my Windows 7 to start up. I'm not sure if this is my PCs problem or windows. It starts up, gives me the ASUS screen where I can go into setup (though messing around in it hasn't helped yet). otherwise it goes to black screen where I can choose start windows normally or launch troubleshoot. if I pick start normally the windows logo comes up, loads, tursn black, and resets the PC. If I choose troubleshoot, it goes black for several minutes, shows the Windows 7 BG, and just gets stuck there. I'm not sure what to try to get it to boot.
It is an HP Pavilion dm3 Entertainment PC running Windows 7 Home 64-Bit. The computer had several problems with it so I did a system restore that is built into a recovery partition. The install went fine, but then when it was loading in the 2nd time... it locked on Personalized Settings: Microsoft Windows Media Player. The problem I am having is that the laptop does not have a CD drive so I cannot put in a Windows 7 disc and run a chkdsk /r. I can log in to the machine if I go into safemode with networking.
I have this absolute annoying issue with my Windows 7 Home Premium. If I leave my computer on for roughly an hour I will go and attempt to either rename a file or search a file in the normal os search menu. The second I type one letter the os locks up and I am forced to end the explorer.exe process. I have recently reformatted my computer no more than 4 months ago and prior to that I was given the same problem. I heard and read in select online searches this has to do with shell extensions of some sort
I have been having this problem for about 2 weeks. I have tried disabling various services but have not had any luck narrowing it down. I have attached the Dump & System files. I am unable to create a System Health Report since it cannot be created in Safe Mode and my computer locks up before I can create it in normal windows.
My computer is a Toshiba Satellite L675D Laptop with Windows 7 Home Premium 64 bit w/ SP1 OEM. It's about 1.5 years old.

I can take pictures of my system later tonight.My issue is that when I boot my computer, sometimes Windows 7 will get start at the Win 7 glowing icon (startup screen). When it locks up there is no HDD activity. Occaisionally, after power cycling the desktop a couple of times it will get into the windows desktop. Sometimes I can do a few things but then it will lock up and either be really slow or it will lockup, then unlock, lockup, then unlock.When I boot into safe mode with networking everything seems okay and I don't experience any lockups. Now all of this never used to happen. I recently moved (for a job) and a company had packed up and shipped my desktop PC. They had packed it really well. But before the desktop was shipped everything seemed to work fine. When I unboxed it and setting it up in my new place is when it started behaving this way.
I am using an HP Pavillion DV9700 laptop BIOS F.2C AMD Turion 64x2 TL-60 2.00 GHz 2 GB on board Windows 7 Home Premium, 32-bit OS, all updates installed
Somewhere, after a Windows 7 update many months ago, the problem started. I had no problems before. It started with the OS not recognizing the optical disk drive that came installed with the laptop. The computer's set-up BIOS recognizes the drive as being there. The optical drive does not show in Device Manager. I tried changing out the disk drive, it did not work. Soon, Windows 7 would occasionally lock up at the boot screen, but work fine on a cold reboot following a lock-up.
But then the lock-ups became permanent and cyclical. No amount of reboots would facilitate. I went to do a clean install using an external USB optical drive and accidentally discovered it cured the problem! The laptop will not lock up if the external USB optical drive is hooked up and turned on when starting the computer. I tried a clean install of the operating system. I tried updating the drivers. Windows 7 always recognizes I had problems booting and sends the error messages to Microsoft.
Earlier today I turned on my Toshiba laptop (Satellite P855-S5200) and got some sort of error screen, and then it brought me to a screen asking if I wanted to do a system repair or start windows normally. I chose system repair, but then it seemed to get stuck in that process (It was taking forever and nothing was happening), so I turned off the laptop (I know, big no no), booted in safe mode, and did a system restore to a restore point from about a week ago. The "starting Windows" screen came and went, no problem. Everything seemed fine till I got to the User Selection screen (the default blue one with the little hummingbird or whatever). Then it just sat there on that screen. I could see the hummingbird and the little squiggly lines, but there were no buttons to click my user. I just let it sit there, and after about 5 minutes, the user names popped up, and I was able to continue using the computer without any problems, no other speed issues whatsoever. It now makes me wait every time, always about 5 minutes, before the user names pop up. It does this when I restart the machine and when I try to switch users.

Not sure if this topic goes here anyway I am trying to use two active windows in windows 7.What I'm trying to do is allow 2 people on 1 pc and do 2 separate tasks, I know you can have 2 separate monitors and I worked out how to have 2 separate cursors controlled by their own mouse but Windows only allows 2 active windows at the same time
I have both a windows vista and win 7 laptop, while using the computer if more then one window is open. The inactive windows will pop up over the foreground window. Maybe part of a new windows feature? I don't think its a malware issue its present on both laptops one being brand new. It makes working on the computers rather hard ...
I have used MapObjects2 in VB application as reference for map interface in Windows XP environment very well. But when I tried the same in Windows 7 Ultimate environment. It did not work. It did not or could not link to have the reference to MO20.ocx files.
