BSOD Before Login Screen - No Errors Reported In SFC / Scannow
Jun 11, 2010
I bought my daughter a laptop. I dont have a windows 7 disc as windows 7 came already installed. However yesterday when she turned laptop off to have her tea and when she went back to use it. We noticed that after the windows logo had appeared the screen stayed black we could move the mouse but that was about it. I put the laptop into safe mode and checked for viruses malware and trojans, also tried a system restore but that didn't seem to do anything and found nothing suspicious.
Also did the sfc /scannow no errors reported. I read that you could get into the Task manager and stop the explore.exe and add a new one and start it again. This however I cannot try as I cant get past the windows logo screen.. So in a nut shell here's what ive tried and failed at doing..
1- Startup repair
2- System restore
3- (Via Safemode) checking for viruses, malware, trojans.
4- (Vie Safemode) updated to latest Graphic Driver
5- Tried this >> Windows 7 Black Screen Of Death Fix << did its job but after reboot went back to black screen
6- Removed battery and pressed power button for 30 - 60 seconds (to no avail)

After running sfc/scannow, no matter how many times I run it, I continuously receive the same error(s).sfc/scannow Beginning system scan. This process will take some time.
Beginning verification phase of system scan.
Verification 100% complete.
Windows Resource Protection found corrupt files but was unable to fix some of them.

Recently I had an issue with Chrome (which is now solved), But during solving the error I done an SFC Scan as it was a windows .DLL that was reporting to be in error and the scan found a few files that were un-repairable.I also downloaded a Windows 7 Installation Disc from Digital River; Here.After extracting the required files from the .iso files with 7-Zip, I changed the ownership of them and 'Moved and Replaced' the old files with the new files.
These are the files I replaced;
autochk.exe
blbres.dll
netcfgx.dll.mui
icardres.dll
winshfhc.dll
I then re-booted in safe mode with CMD Prompt and re-scanned with SFC, but the same files are reporting they are in error. Are they important? Is there another way to repair them? I am running Windows 7 Home Premium, I have attached the most recent SFC Scan.

I had a BSOD two days ago coming out of standby and ever since the system locks up after reaching the desktop whilst trying to log in. Logging into safe mode works perfectly fine and also logging into the Ubuntu partion has no problems. I have run malware bytes and hard disk diagnostics and found no problems.

My computer is running on a Windows 7 Home Premium OS, it's about two years old, Lenovo brand. I won the computer a while back, and do not have a Windows 7 Op.disk. The problem is, a while back I got this virus called Wolfram Antivirus software, and tried to do everything I could to remove it. It was a pain. The thing is, I think I might have accidentally deleted something in RegEdit, and now my computer (on the ultra rare occasion that it gets to and past the login screen) will tell me that it has encountered a critical error, and will restart in 1 minute.When it does reboot, what will happen, is it will get to the picture of the swirling Windows symbol, but then reboot before making it to login screen. Then it will ask me to do a system repair or start up normally, because it shut down unusually

i've been having bsod on win 7 for over a week, i have had these problems previously, win 7 32bit to 64bit reinstall worked last time. this time i have tried installing win 8 pro 64bit to separate ssd drive. clean install, also having similar issues. i've started debugging some of the dumps. a few have pointed to avg and the gpu. i uninstalled avg and used driver sweeper to remove video, sound and ethernet drivers. this had only made the bsod take slightly longer to happen. sometimes the are happen under load (utorrent and playing bangbang racing), other time just Internet, and even while idle(just utorrent). i have stress tested the gpu, cpu, and run check on ram and hdd. i am leaning to faulty motherboard but i don't want to fork out for a new one until i cam be 100%.

So my pc has been randomly freezing and locking up after an hour or two of use and i cant figure out why. I have updated my graphics card and bios.I have tried both ram sticks in individually into the first slot, so unless both ram sticks went bad at the exact same time, they should be ok. I did try to run memtest overnight, but upon waking i found that the pc had restarted.I have cleaned out the pc of dust, and the heat seems fine on cpu, gpu, and mobo.I have run a full av scan with malware bytes and cleared up registry and temp files with ccleaner.

As of about 3 days ago my Dell Inspiron N7010 (Windows 7 Home Prem 64bit) fails to boot up. It gets to the initial Windows screen before the login screen and freezes, then sends me into Startup Repair. [code] I've tried running the diagnostics and get no error codes. I've tried restore points, memory diagnostics.. pretty much everything except factory image, with no success. I have a lot of government programs installed on this laptop, so.

i have a Dell Vostro 1520 and im running Windows 7 with a 32bit. It is only 2 years only. It started about a month ago. I was on my laptop viewing and deleting some unwanted photos i had. A few minutes later i realized that i deleted a photo that i wanted. So i went to the recycling bin and restored that photo. When i went back to my photos and went into the album, it said something like i do no have permission to access this folder. Please press continue to get full permission. I clicked continue and i got the access i should have. Now i tried many more random folders and the same thing happened. Also when i came out of the folders, the folders had a big pad lock sign on the front of it. After that i shut down the laptop and went to turn it back on. The laptop will power on like normal. I can press f12 for the boot options. which i have already tried many times. I also tried it in safe mode and what-not, but still nothing. I can hear the fan and stuff spinning up like normal. I have also put and CD into the CD ROM and that spins up fine. So after the Dell logo on the screen, it goes black and stays that way with the cursor. You can move the cursor around no problem. I should also add that the battery light is and has been flashing for a good wile. Its flashing orange and blue. I'm wondering if this has anything to do with the battery. Because my laptop will not charge with the AC adapter in it for many months now. It will only stay powered on with the AC adapter plugged in. One more thing. The LED lights over the buttons. None of the are flashing, besides one, on the far left. And i cant find out anywhere what this LED light stands for.

My son has a Toshiba Satelite P205 that he just upgraded from Windows XP Home Premium to Windows 7 32-bit. After the upgrade completed the computer booted fine. The within 20 minutes he got the BSOD and the system rebooted. Now he can't get Windows to fully start. We've tried all of the options from F8 with no success. We have the Toshiba System Recovery Disk but it won't launch. (The Boot sequence has been changed to boot from CD/DVD and then the Hard Drive.)The Memory Diagnostic from the Windows 7 disk ran fine with no errors. I'm thinking I might need to re-format/wipe the drive to start fresh but don't know where to obtain a boot CD(no floppy drive on this laptop). Does anyone recommend a software that I can purchase to clear everything without destroying the CD/DVD accessibility so I can then use the System Recovery Disk to put it back to the original factory Settings?

I have an Acer aspire 5732Z. I turn my laptop on and it shows the starting windows screen then just goes to a black screen with a cursor. I tried to do systems restore but it said that I did not have a system restore point. I cannot start in any safe mode. I have all my pictures, uni work etc., and I am terrified I've lost it all. I've only had the laptop a year.

Okay so lately I've noticed that my PC isn't displaying the BIOS splash screen anymore and skips straight to the Windows login screen.It didn't really bother me until today when I wanted to boot into Ubuntu and I couldn't select which OS I wanted to use.I'm pretty sure the problem isn't the BIOS itself since I unplugged all the peripherals except the speakers, removed all the RAM and the BIOS did beep repeatedly. And given enough time, I can boot into windows (and only windows ).Apparently people have had this problem before and all the solutions I've read such as "Press 'del' to go into your BIOS!" really doesn't help since I can't see anything in my BIOS menu.The only solution that made sense to me was that my CMOS battery could be dying. I haven't changed my rig since I built it in 2009. The only significant event that happened recently might be that Windows updated itself.
-PC doesn't display BIOS splash screen
-Can't see messages displayed by system
-When windows does bootup, everything runs just fine
-Haven't changed rig for ~3 years

Everything shows up fine until the welcome screen after that it normally used to fade to the desktop but now it goes blank. The screen in Black with only the mouse pointer. Its not hung, i can move the mouse pointer. Then after a minute or so it advances to the desktop. Everything on the desktop loads up in less than 5s. The PC runs fine, it is really fast as there are only a few programs, but only boots slow. My total boot time is about 3-5 min. I think it should be like in a minute or so.I have not tweaked much with the system but have installed a few programs like MS office, Nero, Acrobat and Photoshop. These are the only heavy programs in the PC right now. The only games on the PC are AC1 and AC2. I have uninstalled my graphic driver and reinstalled. I already minimized the programs in the msconfig>startup to the minimum. I have run ccleaner, spybot s&d, Antimalware and i also have a trial copy of Kaspersky AV (upgrading later to 1-year license). there are no peripherals attached during boot except the USB keyboard and mouse. A printer is attached too but is most of the time turned off.

My system had been very slow and hanging for a while now, so i decided to to check for errors in my drive C. Since then anytime i put on system it show the BSOD at approximately 3 minutes after booting. Currently my system only works fine in safe mode.

I have been trying to resolve some BSOD I got on my PC. To do this I also re-installed windows several times. I build and install everything by myself for years, but this is the first PC with a lot of BSODs. I used the Debugging Tool for windows to check the minidumps by myself, but as far as my knowledge goes, I didn't find anything special in there. The only thing that was obvious was that in all BSODs the ntoskrnl.exe was involved. This was something BlueScreenView revealed also. In my opinion however it seems there is more to it, since the ntoskrnl.exe could probably also crash because of another driver or hardware problem.On my previous fresh Windows 7 Install I did found out once that alot of BSOD I had at that time were caused by a bad Creative driver for my X-Fi. On the web I found a useful hint, because other X-Fi users pointed to the beta-drivers for the card. The official Creative drivers are almost two years older then these beta drivers, so obviously the beta drivers should be the first choice. These drivers are the ones I use now. I also had some problem with my OCZ Vertex 3 MI, like most owners of this hardware, and the problem was the unstable firmware. I am using the latest firmware now, which is 2.15, and that made the system alot more stable. The third problem is happening in POST: my logitech G110 keyboard features an USB hub and connection for media. These kind of USB keyboards had some problem with recognision and initialisation in the UEFI BIOS. For that I also updated to the latest BIOS for my motherboard.
All in all you can see I discovered and tried to fix a lot of different causes for BSODs. I also ran memtest once on the system for two hours, but this was in Dual Channel setup. Didn't gave any errors anyway.The latest minidump is created by the use of Verifier. I turned verifier on to test the two drivers for my AMD HD6970(crossfired). After 5 minutes in windows the BSOD appeared. I am using AMD Catalyst 12.1 drivers. I tried this, because the BSODs all are different then the ones I had on previous Windows 7 installations (on the same pc), but the only thing I changed in the current installation, was the AMD 12.1 drivers.I reinstalled windows about two weeks ago, after using Secure Erase on my SSD. I installed only the latest drivers for all the things that need drivers. The complete installation, including windows updates and drivers, was without any fault. One day later the first BSOD appeared, etc. I use the system to play Battlefield 3 only, since the fresh install. Strangely, I played more then 50 hours in the game, without any crash or BSOD! The new AMD FX-8150 processor is the first to support native 1866 MHz DDR3. The motherboard specification showed that the board supported 1866 (OC), thus it's seen as an overclock. I set all settings in bios like the ram specificiation told, which is: 9-11-9-27 2T @1.65V. Still, it could be that the 1866 MHz is too much on standard NB voltages? It's something I couldn't find an answer to on the internet, and since I never overclock I don't have that much experience with the voltages.
All BSODs happened in different situations, like just after windows log in, or when I start a program, or when idling, or when browsing the internet.Since I couldn't figure out any more usefull details out of the minidumps, I hope someone here with more experience could check the attached files.

Computer is a few years old, a home build, running Windows 7 Home Premium x64. Haven't really had too many problems other than the occasional BSOD or random restart, but it's gotten a lot worse lately so I wanna get to the bottom of it.The two errors I've gotten are Memory Management and System Service Exception, both seem to be linked to the ntoskrnl.exe file. I also ran the System File Checker and got the following error reported: "Cannot repair member file [l:24{12}]"kerberos.dll" of Microsoft-Windows-Security-Kerberos". Lastly I ran the windows memory diagnostic and it detected several hardware errors.
1)A system restore to a couple weeks ago
2)Repair the system/OS with my Windows 7 disc
3)Replace the RAM
Wanted to post here before I try any of those though. Whew ok sorry to be long winded but wanted to provide as much info as possible.

I have had a very solid stable system since 2010, then I decided 6 GB of RAM and a 9800GT/GTX560Ti wasn't enough. I sold these parts away and replaced them with 24 GB of RAM and a GTX560Ti 448 edition. The instant I throw these new parts into my box I start getting the two different BSoD errors (the ones in the title). I have cleared everything of my previous overclocks with the upgraded components.System Specs: (bolded is what was introduced to the system which created the errors)Windows 7 Professional x647 930EVGA 132-BL-E758 (Motherboard)EVGA GTX560Ti 448 FTW EditionPatriot Extreme Performance (24 GB of RAM)If you need to know anything besides the core components that I have, let me know. Attached are the dump files.
The story so far:I have ran Memtest overnight on all the sticks of RAM and nothing comes up, it claims they're all good. I'm not sure how to test the graphics card, but what I can tell you is that I can login to Windows and within 5 minutes the BSoD shows itself. When in safe mode, (where I am right now), it runs more stable, but I have had it BSoD in here as well; It's just nowhere near as often. So, this makes me think its not hardware related and hopefully it's not because I have no other RAM sticks or graphics card to test with.My thoughts:I only used 3 of the 6 slots for RAM on the motherboard before this upgrade so initially I thought maybe I had a bad slot. I can't disprove that, but I still get the BSoD when using only 1 stick of RAM in a slot that was previously known as working. I uninstalled the graphics driver for my old GTX560Ti and downloaded the latest driver for my new graphics card and still get a BSoD.

After a long time of trying to fix this problem by myself, i turn to the pro's for help I've been having a lot of BSOD errors while playing games and occasionally during browsing / playing movies on my pc. The most common error messages include:
BAD_POOL_CALLER
PAGE_FAULT_IN_NONPAGED_AREA
IRQL_NO_LESS_OR_EQUAL
Atikmdag.sys error.
After some research i thought it might be the RAM, so i went to the pc shop and my RAM was still under warranty so they gave me a new one and the problem seemed to have gone for a short time, then it came back and has been haunting me ever since. It usually occurs during gaming: the pc eithers shows a BSOD, or the sound loops and the screen is full of blue/red/green lines or it just resets. I added some minidump files of the latest crashes, hope it helps to determine the problem.Might it have something to do with my old BIOS version? 14.04 dated 28/05/2010?

My wife's computer with 7600 RTM 64-bit installed is experiencing about daily BSOD errors. She had similar problems under XP 32-bit as well and I tried replacing various components and drivers to see if I could resolve the problem. Nothing seemed to help. The problem might be resolved for a while, but eventually always came back regardless of what I tried to do.
Restarting the computer Windows presents a "recovered from serious error" dialog and displays an error message. The message we typically get is similar to:
Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033
Additional information about the problem:

I'm getting these errors more frequently, and usually when I'm browsing the web. I just got the 0x0A one when I installed the Asus mother board Utility tool for my P8P67 LE REV 3.0 mother board.I get the 0x0A1 error off and on, about 3 times now I've gotten it. I've attempted to use memtest86 but to no avail. I burned the iso onto a disk and had the system boot disk first, nothing happened, it booted normal. I tried the USB stick way and install it using that method, attempt to boot from the USB first in the boot priority and still... nothing.

I have recently built a computer with the following components:
Asus 990fx Sabertooth motherboard
Zambezi 6-core Am3+ cpu
16 gb g-skill ram
180 Gb SSD
1 TB 7200 rpm HDD
2 MSI GT 560's
Every time I go to install Windows 7 it seem to be getting a different error. It will get to various stages of the install (ex, i can click on the language settings and the install button and then crash, or it will get to expanding files and crash, or it wont even get to the language settings page) The BIOS runs fine and recognizes my RAM and my CPU. How I can install windows 7.

While attempting to restore a previous backup of my system (with Norton Ghost 15), I got an error, and the system rebooted. Upon reboot, I get the black screen of death with just the cursor instead of the usual login screen. I have tried the following thus far: These all give me the black screen of death with movable cursor:boot in safe mode boot in safe mode with networking boot in safe mode with command prompt last known good configuration I did an initial system startup repair which went through and said it repaired it, rebooted, but no change. I did a pre-boot diagnostic test - nothing memory test - nothing tried restoring from restore point, but it says I don't have any (LIES! BLASPHEMY!) tried restoring from restore point on external disk - seemed okay, then failed. chkdsk - found some stuff, fixed it, no change. tried ctrl+alt+del on black screen of death - nothing
Now, I know that the hard drive itself is alright, that is, the information is still all there still. While I can't give you exact specs, I can tell you that I am on a Dell Studio XPS running Windows 7 home premium 64 bit. I'm at a loss as to what else to do. Despite being a black screen, with just a movable cursor, the system still appears to be running, as every few minutes, it will show the "thinking" cursor, where it shows the little circle next to the arrow.

I have some problems with BSOD. It can happen few times a day, and it can appear after a week without problems. Usually it happened when I use the internet, but yesterday, for the first time it happened 2 minutes after I turned on the computer, without doing anything.I updated all the drivers without any positive result.
