So, I built a new computer a few months ago and am having some problems running 3D games. Normal operation (web browsing, videos, etc) seems to be OK. What happens is that I start a game, and after running for about 20-30 minutes, the computer just freezes completely - no error message, no restart, no mouse or keyboard input possible, etc. This has happened with Crysis, Call of Juarez: Bound in Blood, and even older games like NWN2 or even Far Cry. I end up having to hard reset to fix things. I would guess that the problem has something to do with my video subsystem since the computer is fine during non-gaming use.
Specs are as follows:
Phenom II x3 720 BE (stock 2.8 GHz)
ASUS M4A78T-E mainboard
Mugen II heatsink
4GB G.Skill DDR3 1333
2x Radeon HD 4850 512 MB
WD Caviar Black 1TB
Silverstone Element 500W PSU
Lian-Li PC-7B case
Windows 7 x64 Professional
Latest (9.10, 10/22/09) Catalyst drivers
I imagine some people might think the PSU is not beefy enough but I'm not sure that's it - it's a quality unit. See a pretty comprehensive review here: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=13.
Heat might be an issue but the case does have 120mm fans at the front and back, in addition to 2 120mm fans strapped to the heatsink (in push/pull config).
Anybody have any thoughts/suggestions?
