My pc keeps crashing/Re-booting itself whilst im playing games. this has only started happening recently and only on certain games (silent hunter 3, toca race driver 2, battlefield 2) my system meets the minimum spec requirements of these games tho. i have geforce fx5200 graphics card, 2.19ghz amd processor, 512ram and loads of free hd space, running windows xp. could anyone help please.

does it crash doing anything else or just on games?

just on these particular games.

is your memory close to the min spec of the games ? have you got a stick of memory that's starting to fail

2 of the games minimum spec is 512 which is what i have but the other game is recomended 512 but can run on a minimum of 256, and its this one that crashes most. sometimes before a crash the sound goes funny too which is weird. for instance if there is speech the voice goes really deep and slow but the graphics remain fine then will just reboot.
