could be - getting rid of dust is never a bad idea you could also run it up with the side off and double check all the fans are actually going round (sometimes the bearings go), and double check things like the CPU heatsink is seated properly on the cpu if that ain't it, then it could be something software-ish - but if it's 10 minutes whatever the game (no matter how long your PC's been on for previously) then it sounds like it's a runnning under load / heat problem |
