are you overclocked any ?
what mother board you using ??

has TF2 ever run for over an hour on ure current setup ?

Whenever you begin to have performance problems, you need to set some performance monitors to watch your PC. Are you running Vista or XP? Vista has some great internal monitoring tools. XP not so much. But there are 3rd party tools too.
