I've been trying to fix this problem with no success. I can get the CD ROM to open when I boot up the computer, but when I get to the main screen after start up it seems to have lost its power. Im wondering if this problem is being caused by the PSU. I will get random re starts that seem to have been happening more frequently. The PSU is 600w and came with my case, and I have heard that the case PSU can be quite crappy most of the time. System Specs AMD 64 X2 Dual 4600 2 gig RAM 7600 G Force Video Card I also have a portable (external) WD HD hooked up which I know is draining some power. Anyways any help would be nice, thanks.
