Do you have another computer to test your parts? How long was it running before it shut off? What were the temps like before it shut off? On a new system it could be anything, are all the parts brand new? So when you hit the power button it does nothing, or do the fans spin and no boot? If you hit the button and it does nothing, the power supply might have died. You might try resetting the cmos by moving the jumper, then back again and try to boot. Post back with some info. Mike
