I just finished building my pc. I installed windows with no problem. The problem starts when I insert a cd into the cd drive. Everything is fine for a few seconds and it will read the disc and show the icon in the "MY COMPUTER" window. But every time I access the cd and you hear it start to spin up the computer will reboot itself. Then it will continue to reboot everytime it reads the cd before loading the O/S. This happens with ever disc I use and with multiple drives. I checked the inter temp and it is running at 40 degrees. Which doesn't seem hot at all.. So what else could it be? A power supply issue? A problem with the installation of windows? Any suggestions would be much appreciated.
