Windows 7: Unknown cause BSOD 0x0000007E

My crash occurs at least once daily, seemingly without provocation. I do not game or tax my system, to my knowledge, beyond its capabilities. I use Photoshop and related imaging programs most often, with Outlook and Word following. This accounts for about 90% of my computing.

Running a program called "BlueScreenView", it hints that the file afd.sys is possibly responsible. My BSOD log file is attached. I would appreciate any help that might hint at the cause of this.

The only other symptom is that sometimes my computer CRAWLS at a snails pace. Occasionally it's because my scheduled backup is running, but often there is very little running, but yet I get several second pauses between typing characters, and very jumpy and delayed mouse movement. Not sure if this is connected somehow. I've run various malware scans and virus scans to no avail.

Thanks in advance for any help.

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Windows 7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

ZigZag: Thanks again for your help. I ran the MemTest this morning. By the way, the newer v4 did not run for some reason. I got the first opening screen, but then no action and no response from keyboard entries. So, I had to run the 3.? version. All checked okay. Getting ready to run verifier following your suggestions. Will report back. Meanwhile, it crashed again last night (I left it on all night). New BSOD report attached. Not sure if this adds any new useful information?

ZigZag: What do you mean by DMPS? Is that the results of my running the Verifier, or something else? Just want to make sure I give you everything you might need. Thanks.
Bob

ZigZag: As always, thanks for your ongoing help with this.
Well, I didn't crash all day yesterday, but finally last night my computer was once again brought to its knees. I'm hoping this latest report will bring me (you) a bit closer to getting this annoyance resolved. Attached is the latest BSOD report which I hope contains some new useful information. Let me know if you can help.

Thanks,
