Hello everyone.
When someone googles for the GUID code of this error, this is the first topic that comes up.
I've found my solution and thought this is a good place to share it, since this topic is the first source of solutions to hundreds of future searchers. Even if the last post is 160 days ago.
I've tried most of the tips here to no avail. Then I did two things at once; disabled overdrive in ATI control center, and changed my RAM settings to from "Turbo" to "Standard" in my Gigabyte BIOS. (there is standard, turbo and extreme).
I have no idea why it was set as Turbo. Maybe they just didn't want it to look like "slow-standard-turbo", so they changed it to "standard-turbo-extreme".
My specs:
Intel i7 860
Gigabyte GA-P55M-UD2 P55
Transcend 2GB DDR3 1333Mhz
Radeon 5770 1GB
Anyway I knew that the crash occurred whenever I set uTorrent to download a big file over night. Not once did it survive the 24h mark, always crashed before that.
So after these last 2 changes, I set it to download 80 gigs - so it would download for about 18 hours straight at full speed - and it's been running for 28 hours so far.
