Sudden framerate drops

[Guest]

Hey,
Ive had this problem for a while now. I play any game, it runs fine, then
after 30 - 40mins the framrate drops to about 10-15 fps and stays there,
untill i completely restart the comp. Any ideas?
All drivers up to date, defragged many times, no virus\spyware, all
background programs including AV closed etc. Only exception is that the SiS
AGP drivers are only compatible up to XP - there arent any Vista ones...but
to my knowledge that doesnt tend to cause such problems?
Incidently the problem occured shortly after changing from an ATI to NVIDIA
card...but i have thoroughly whiped ATI drivers off... :/

Could be the video card is overheating after playing for some time.
