Windows 7: 0x7e BSOD in Windows 7 - frequent, intermittant

0x7e BSOD in Windows 7 - frequent, intermittant

Hello. This is my first post, so please have mercy on the newbie. :-)

I've been getting frequent (several times a day), intermittent BSODs with the following error numbers:

0x0000007E (0xFFFFFFFFC0000005, 0xFFFFF80003222FB2, 0xFFFFF880030F8938, 0xFFFFF880030F8190)

...and no associated file name or error text (such as THIS_IS_YOUR_ERROR_TEXT).

I have recently scanned my RAM, and it had no errors. I've been using my hard drive for a long time with no errors until I installed Windows 7. I checked it for bad sectors about 6 months ago, and checked its SMART status days ago. My motherboard is new, and I just recently (after installing the new MB) installed Windows 7 on my hard drive, loaded drivers from the vendors' websites, got all Windows updates--security, plus a few others, including services packs, installed the various programs I tend to use, and installed Steam and my other games. I started getting the errors/BSODs shortly after installing Windows, and before all the updates had been completed. I've been trying different solutions suggested on the Web, and upon *thinking* I'd solved the problem each time, I'd install more software, and eventually get another BSOD. Each time, except from the times I've used verifier.exe to check drivers, the error code has been the same. The times I've used verifier.exe, the error code has been 0xC9.

I've used BlueScreenView to look at the errors, and found that when verifier is not used, the two suspect files are cng.sys and nvhda64.sys. When I've used verifier, the suspect files are nmserial.sys and ntoskrnl.sys--which makes me think that the verifier has been finding mostly non-problematic drivers and crashing on them, rather than finding the cause of the 0x7E error. The nmserial.sys file is for my MosChip PCI parallel/serial port card, which I use for my old parallel laser printer. (That thing is nearly indestructible... :-) )

I'm using a custom-built gaming PC with the following specs:

OS: Windows 7 Ultimate 64-bit
CPU: Intel Core 2 Duo E6550
Motherboard: Biostar P43-A7
RAM: 8GB DDR2 800MHz
Video Card: Zotac GeForce 560 Ti
Sound: On-board Realtek HD Audio
Hard Drives:
500GB - Ubuntu Linux 11.04 with GRUB2 boot loader (primary)
750GB - Windows 7
1TB - PERSONAL (my important data)
1TB - PERSONAL2 (backup of PERSONAL)
Keyboard: Microsoft Comfort Curve 1.0 (with software from Windows Update)
Mouse: Logitech G9x (with software from Logitech)

It's worth noting that the video card, motherboard, and 4GB of the RAM are new.

I have a lot of experience with computer repair, but I've rarely ever come across something this stubborn, so I'd greatly appreciate your help! I'm also pretty new to Windows 7.



P.S. The problem happens most commonly when I come back to the PC after several hours of it sleeping, wake it with the keyboard, or mouse, then try to make it do something. It's BSOD'd after checking a box on the Assassin's Creed: Brotherhood download manager (but before clicking anything else), pausing Defraggler and telling it to resume (one after the other, to get it moving again), and from doing several other tasks that I don't remember right now. It also happens at random times when the PC hasn't been sleeping. Also, the whole PC slows to a crawl whenever I'm trying to do any kind of file transfers to/from the HD, and using a web browser or anything else at the same time. I'm using Firefox 4. In Linux, these problems don't seem to exist. Perfmon tells me that my PC has a lot of interrupts/sec., so I'm wondering if that's part of the problem. I've set the power management in Windows so that it doesn't turn off the HDs, but it seems to be doing it anyway.

Windows 7 Ultimate 32 bit

Hi Dane, welcome to the forum and to Windows 7. Don't worry about being a newbie. We were all new to Win 7 and Seven Forums at one time.

I looked at all of you dumps. One dump was inclusive and corrupted. Driver Verifier stresses the third party drivers; generally, if Verifier identifies a third party driver, that driver has a problem. When Verifier identifies a Windows system driver or file as the problem, it is usually because something else is causing a conflict. The driver, nvhda64v.sys, blamed in the bugcheck 7E dumps is nVidia audio chipset driver. It is up to date. The dumps showing bugcheck 7E indicate memory corruption.

I suggest you try to eliminate potential sources of conflict as a way to begin your troubleshooting.

1. Download and install Microsoft Security Essentials: MSE is superior to Windows Defender, runs smoothly with Win7 and offers superior protection vs Defender. Installing MSE will turn off Defender. I do not know if Defender is causing a conflict; but I do know that MSE usually runs very nicely with Win 7.

2. I find two outdated drivers with the potential to cause conflicts, memory corruption and BSOD's. Try to update these drivers through the links provided. If there is no update dated July 13, 2009 or later, uninstall the software/hardware these drivers are associated with.
BS_I2cIo.sys Mon Jun 16 02:45:18 2008 - BIOSTAR I2C I/O driver
Found in BIOSTAR BIOS Flash Utility. BIOSTAR :: Download.

GizmoDrv.SYS Sun May 18 01:24:02 2008 - Gizmo Project - Arainia Solutions. Gizmo Central -- Get help, make suggestions, report bugs.
3. For troubleshooting purposes, uninstall your MosChip PCI parallel/serial port card since it was blamed in two Driver Verifier enabled dumps. You can always reinstall it once you know your system is stable. If you start having problems after you reinstall it, you will know it is one of the causes.

4. When you say you recently scanned your RAM, what did you use to scan it and how many passes? Most of us here recommend Memtest86 and run it for a minimum of seven passes. Here is a good tutorial on Memtest86: RAM - Test with Memtest86+. If you did not use Memtest, follow the instructions in the tutorial and test your RAM. Post back with the results.

Take these four steps and let's see if your system is more stable. If after following these steps you get another BSOD, upload the dump and enable Driver Verifier again following the instructions in this tutorial: Driver Verifier - Enable and Disable. Let Verifier run for about 36 hours. Upload any and all Verifier enabled dumps.

This is a very common bugcheck.  Usually the exception address pinpoints
the driver/function that caused the problem.  Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003.  This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG.  This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG.  This will let us see why this breakpoint is
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff80003222fb2, The address that the exception occurred at

Windows 7 Ultimate 64-bit

Thanks, CarlTR6, for your reply.

I've uninstalled the Gizmo virtual CDROM software, and I'll be removing the MosChip parallel card shortly. The Biostar thing was a BIOS flashing utility, so I installed their two BIOS patches that I'd not yet installed and uninstalled the flasher. Since I installed the flasher as a result of the BSOD, I doubt it was the problem, and the flashes I installed didn't seem to relate to it...but it doesn't hurt to try.

I actually was using MSE, but uninstalled it because it was causing really terrible performance, and because I thought it might be part of the cause of the BSODs. I'm pretty hesitant to install it again since it made my computer basically unusable. I'll do some scans with some other software, though, to make sure I'm not infected. I do think that the poor performance is related to the BSODs, but I don't know how yet.

With regard to the performance problems, I think it's worth noting that I recently upgraded my video card from a Nvidia 9800GTX to a GTX560 Ti, but in most games the performance seems to be about the same, even though the new card is MUCH better than the old one. In Arcania, I expected to be able to crank up everything from Medium to High, but even on Medium with this new card, the game is choppy. The Windows performance analyzer seems to switch back and forth from thinking my video performance is about 7.6 in both areas to 1.0. Like I said, I'm almost certain that the performance problems are related to the BSODs.

I'll work on what you said and talk to you later.


Edit: I just ran the performance index again, and it said that it couldn't measure my CPU performance. It was giving me this error about the hard drive when I had MSE installed.

It is unusual for MSE to cause a problem on Win 7; but it is not unheard of. Keep going and enable Driver Verifier.

BSOD fixed! Other problems remain.

OK. I've had Verifier running for several days now, after removing the parallel card, and have not gotten any BSODs! I've turned off verifier. Thanks very much for your help with this!

My new quad-core CPU (Q8400) has finally arrived after about a month of waiting, and I've installed it, but my PC is still running depressingly slowly! I've re-run the Windows performance evaluation on my PC, and gotten higher numbers, but the hard drive section is giving me this:

Caution: Based on the results of the WinSAT Disk assessment, your system drive may have slower response times under some workloads. Performance results will depend on the specific applications used and the amount of memory available. If your experience is satisfactory, no action is needed.
Indeed, whenever I do anything at all that requires a lot of activity from the HD, everything slows to a crawl. For example, just opening a Google search link in a new tab in Firefox 4 often takes a minute or more when I'm running defrag or copying files. This is driving me crazy, although not as much as the initial BSOD problem. My HD rates at 5.9 on the Windows 7 scale, and is my lowest score. (Everything else is 7.2 or higher.) Any suggestions on how to fix this? Do you need me to provide any more information?

Thanks, DeanP. If only my old, reliable HP laser printer (LaserJet 5P) didn't require a parallel port! The motherboard has headers for a parallel port, and they don't seem to be crashing the system, so I'm going to try getting a backplate to connect those headers to the printer. I've tried out USB-parallel adapters, but had mixed results...and I'm a bit old fashioned when it comes to PC ports. (I still think that motherboards should include PS/2 ports, even if I'm not using them at present!) :-D

I have an update regarding the slow hard drive performance and high IO wait.

I've discovered that the 750GB SATA2 drive I was using for my Windows installation was faulty. I've since replaced it with a new 1TB SATA2 drive, and the performance problems are a thing of the past. :-) I've also since replaced my 1-year-old power supply, which I think had caused several hardware failures, including my motherboard, video card, and (possibly) hard drive. This HD failure was a bit odd, since it didn't show any bad sectors, even in its SMART logs, for quite some time after the performance had degraded. Finally, bad sectors began to crop up, and when I removed the drive, it had found around 100 of them (and replaced them with reserved sectors).

I've also re-installed MS Security Essentials, and it's working great.

Thanks again for all your help, everybody. I hope this information helps somebody else at some point.


P.S. How can I mark this thread as "SOLVED"?
