I went out and bought some parts so basically I have a new computer. I installed TES:Oblivion and CoD4 and when I tried to play them, after around 5 minutes to around 30 my computer would freeze and the music would loop, Ctrl+Alt+Dlt doesn't work and Alt+Esc doesn't work either, the only thing I can do is a manual reboot. Once I patched Oblivion it ran fine but I've updated CoD4 and it hasn't helped at all. I JUST updated my drivers today and CoD4 is still freezing(both SP and MP). Specs are as follows Windows Vista Home Premium nForce 680i LT sli GeForce 8800GT superclocked edition 512mb Intel Core2 Duo CPU E6750 2.66GHz Hitachi Deskstar 320GB SATA2 HDD 2x 1GB Buffalo RAM Enlight 650W ATX Power Supply ATX12V V2.2 20/24PIN 80PLUS Triple 12V Rails Active PFC 120MM Fan RoHS (SLI ready) as for temps CPU 28-34C HDD 27-30C SYS 26-30C (temps are only 30+ while running games so I doubt it is an overheating problem) I AM running these games on max settings with 1680x1050 and they ARE running perfectly fine with 60+ FPS........until it freezes anyways >_< So is this just a Vista problem or is it my actual computer?
