I just built a new pc. IE: NEW Diablo II ATX tower, MSI K9VGM-V Motherboard, Hercules 500 Watt ATX Power Supply, Sony DVD-ROM, 1 GB Kingston ram, and AMD Athlon 64 processor. I installed a Maxtor 160GB Hdd. When I try to load windows it gets to the format process and immediately shuts down. CPU and internal temp is fine. HDD is not over heating and all my fans are running. I tried a smaller HDD. A Maxtor 40GB HDD and the same thing happened, I got to the format process and the system immediately shut down. It does not try to restart, but the power light blinks and I have to hold the power button in to completely shut the system down. I checked all my connections inside and out not problems there. PLEASE HELP Before I throw it out the window or pull out my hair.
