BSOD in in 3D accelerated apps(WoW, HoN) 0x0000007E

jwigum · 29 Aug 2011

Hey all,

I'm seeing BSOD on a home built machine. It appears to only be happening in 3D accelerated gaming apps, like World of Warcraft(litch and cata), along with Heroes of Newerth.

We've reinstalled graphics drivers, reinstalled Windows, swapped a motherboard, etc.
We've done a memory test, but I can't recall the exact parameters

- x64
- Home built with Windows 7 Pro OEM
- OEM
- September of 2010
- OS reinstalled in April - May

Pretty sure I've got all the logs from the Posting Instructions, but do let me know if I've missed anything!

What was the result?
RAM - Test with Memtest86+

Your dumps blame memory corruption

It's been some time, but I believe it was a triple pass of memtest with 6GB of RAM installed. No errors were found.

Then do a GPU Test

We've run several GPU and GPU memoryf tests in OCCT, with no errors(or logs, but I think that's expected behavior if there aren't any errors).

There have been a couple rapid blue screens recently, sourcing dxgkrnl.sys and dxgmms1.sys. I'll gather those, but I'm going to run through the extensive system memory test found here as well:
RAM - Test with Memtest86+

I agree that there seems to be something funny going on with memory in this system...
