Answer 1

Your Comp is most probably overheating, let is rest for a day or 2 and then try again. and if you still have same problem, then change the power supplier.  

Answer 2

Its not POSTing Power On Self Test ,does the keyboard lights flash..? does it beep many times...? I would pull the bios battery out and clear ,then put it back in and try again.During that half a minute try to put the install disk into the tray and retry...check your wiring and any memory sticks and make sure everything is proper....good luck and remember persistance pays off...

Answer 3

either a power supply, on board video, or it is overheating

i bet it is the on board video is shot.  Easiest fix is to replace the motherboard or call for a rma if it is still under warranty
