Having a little BSOD trouble with VIDEO_TDR_FAILURES that I'd be grateful to enlist some help with.
The crashes occur around 5-15 minutes sometimes after I resume from an S3 sleep and, one time, after I rebooted the machine with the reset button following one of these crashes, but otherwise never from a clean startup from which I can happily game for hours without issue. After the resume from S3 sleep, they can occur while I'm gaming or just web browsing; sometimes everything is fine. They started a little over a month ago (as you'll see from the attached minidump files), roughly around the time that I installed a beta driver for my GPU provided by NVidia (but this may be unrelated). I cleaned this driver off my machine and reverted to an earlier one but the problem wasn't solved. I updated my video BIOS but that didn't help either, so I got used to shutting down my computer cleanly each night for a while until NVidia released a new WHQL driver for my GPU. I installed this and everything seemed to be fine... until yesterday when the problem started up again. I can't identify any obvious reason for everything springing back to life now.
I had a glance through the memory dumps that were generated but couldn't find anything terribly useful (although I'm not terribly experienced with kernel-mode debugging; most of my WinDbg experience is with SOS for .NET applications).
Aside from the driver and BIOS updates described above, here are some other things I've looked at that haven't helped:
-Ran a MemTest: everything looks OK (not that surprised since everything works from a clean startup).
-Disabled/disconnected the two pieces of hardware I was most suspicious about: a Cambridge Audio DACMagic DAC attached by USB (mostly only suspicious because my usage patterns might roughly fit in with the crashes); and a Creative WebCam that is running drivers from 2005 that were made for the x64 version of Windows XP (although these have been working absolutely fine for me for years).
-Ran the system with verifier.exe. No forced verifier BSODs and I didn't see any useful extra information in the one crash that happened while it was running (see 062014-28672-01.dmp).
-Checked out temperatures (although seems unlikely for same reasons as MemTest). Everything looks good.
-Turned off PCI Express link power saving in Windows. No effect.
Here's some system information as requested (although I guess you'll find some of it in the attached files too):
-Windows 7 x64. It is a retail version cleanly installed to a new SSD several months back.
-Age of system varies from component to component. The newest component is the SSD which is only a few months old. GPU is 2 years old. CPU/motherboard/RAM are a little under 5 years old. PSU is 7.5 years old. Floppy disk drive is 22 years old ;-) (yes, really!)
-CPU is i7 860. GPU is NVidia GTX 670. Motherboard is Gigabyte P55-UD3R. PSU is Antec NeoHE 500W. As you probably guessed by now, this is a custom build desktop.
Any guidance offered is much appreciated!
