Some games crash some games don't???

[r34l1ty7]

Really wierd one - been plaging me to DEATH...any help appreciated.

Some games crash some don't

Ones that DON'T:

Team Fortress II, Batman Arkham Asylum, FEAR 2, Unreal Tournament III

Ones that DO - normally 30mins to an 1hr in some games:

Street Fighter IV, Dawn of War II, World of Warcraft, Civilisation IV, Red Alert.

I'm completely dumbfounded but can anyone see any reason what the difference is in these games or know where to look to find out why this is happening..

Cheers,

Al
