What do you mean how? I installed it with a cd. It has been about 6 months since I reinstalled everything. I did not experience this problem until recently--a week to be exact. The newest addition is the PC Power & Cooling 750 silencer power supply I added yesterday. I upgraded because my previous PSU was giving me problems--fan was making noise, my raid drives were not getting the needed power, and it broke my raid about 9 months ago, also before I upgraded, only 2 of the four raid drives was getting power.
When I did the reinstall I unplugged everything. Installed OS, SP2, Drivers for video and Audio, Firewall, AV software (AVG), Commonly used software (Office, DVD Decryptor, DVD Shrink, Firefox,Nero, Picasa, Roxio copy convert, and iTunes. I always try to do it in this order.
