i am having trouble when my computer is running it keeps freezing sometimes after about 15-25 mins or longer and i have to restart it to get it going again i have tried doing a fresh install of windows 7 but it still persists can anybody point me in the right direction as to what may be causing this to happen i have run a diagnostics program which checked the cpu, the hard drive the dvd re-writer and the ram memory and they all passed as ok so i would appreciate anybody pointing me in the right direction yours peterdee.

Does Graphics have its own Fan? I would say Graphics is the Problem You could try Going to Control Panel/Display and try turning down Graphics Acceleration with the Slider under Troubleshooting tab
