So almost two months ago I bought this system:
Intel i7 950 @ 3.06ghz
Thermaltake Contac-29 CPU cooler
Coolermaster GX650W PSU
GIGABYTE ATI 5850 1GB
GIGABYTE X58A-UD3R Motherboard
6GB (3x2GB) 1600mhz G-Skill DDR3 RAM
In all respects it is fine, it runs at good temps, takes overclocks like a champ, produces quality framerates - though in some games and with some internet flash players I will consistently get crashes the cause of which I cannot determine.
The crash is always the same in game, though I have gotten twice now whilst the computer was idling and not in use - the screen freezes up and a sound is produced which sounds something like a BZZZZZZ, a constant buzz (like a rapid beeping which almost blends to one sound) which will continue until I turn the machine off. It however does not happen in all games, so far it has only really been prevalent in Call of Duty 4 and Medal of Honor - which is peculiar because Black Ops and Bad Company 2 do not crash in the same fashion, even though they run on the same engines.
When using in-browser flash players (youtube etc) I will occasionally get an error telling me that the "video driver has stopped responding and has recovered" - the screen will flash black for a second and the flash video I had open will be a solid shade of green. I'm pretty sure this same thing is happening when in-game, though in that instance it is enough to crash the system.
The problem does not however seem to be my 5850, I chucked in my 4670 and got the same crash in Call of Duty 4 after about the right amount of time (usually between 10-30 minutes, though sometimes sooner). I'd never had problems with the 4670 before.
I've tried different PCI-E slots, different drivers, different BIOS's, with and without CPU/GPU overclocks, different fan-speeds, anything and everything I've thought of. All my drivers are up to date for on-board peripherals (audio etc).
After many hours of intense googling I have yet to find the source of the problem. I really want to get this fixed, so if anybody can help me with this I will make you my wife/husband and love you for eternity etc etc.
