Windows 7: Various BSOD messages that occur usually while gaming but not always

Hello. I've been experiencing a wide array of BSOD error for the last several weeks. I am running Windows 7 64-bit and I have an XP 32bit machine that runs in VMWare. Both get BSOD errors. I have removed the video card and used the onboard video and still get the errors. I have also tested various ram sticks in different channels with errors and run Memtest without errors so I have eliminated the RAM sticks as the cause. Checkdisk has found no errors. I've done virus scans with AVG, Malwarebytes and Combofix with no errors. I have also run CCleaner.



I sometimes get display adapter recoveries before BSOD crashes but not always. Errors have occurred while playing Skyrim, DDO online, coming out of sleep mode, browsing in Firefox. Sometimes my machine struggles to start up. All random though sometimes the crashes can be replicated in certain spots in various games.

Any help is appreciated. Thank you

This is actually a bit crazy.
When was the last time you did a full virus scan?
It may be about that time.
Malwarebytes : Malwarebytes Anti-Malware removes malware including viruses, spyware, worms and trojans, plus it protects your computer

Only reason I'm suggesting that is because the memory dumps I'm reading here are all over the place.
It also never hurts to snooze your active antivirus (you seem to be using AVG) when running the games to make sure it isn't causing issues by blocking things it shouldn't be.

I saw nothing in the dumps about the adapter resets, because those are app hangs, not full crashes.

The 5 dumps I went through blamed everything from the system classpnp driver, to memory corruption (generally either bad driver or bad memory at work from those)

Anyhow since this is apparently happening in the VM as well. I think checking the memory may not be out of the question.
RAM - Test with Memtest86+

Thanks for your response. I actually switched from Avira to AVG after I first started getting BSOD errors. I've since run a full scan a few times with AVG with no results. I have also run Memtest86+ for around 5 cycles with no errors. Any other ideas? I'm wondering if it's a bad power supply or MOBO.

I forgot to mention that I have also upgraded my video drivers and the bios since the crashes started.

Here's the thing, every single crash dump is different, and I'm not sorting a pattern yet.
If you get any new minidump files (c:\windows\minidump
Please zip them and attach to new post.
Of course it never hurts to make sure there's nothing sitting under optional in windows update that may have an effect as well.

Well I thought everything was good after I reinstalled windows 7 on a different hard drive but the BSODs have returned and are still random. Any ideas are appreciated. Thank you.

I ran memtest again last night and there were no errors after 7 passes. I'm thinking it may either be the psu or mobo.
