Will not boot!!! Tags: Motherboards Computer Boot Last response: January 17, 2010 8:44 PM in Motherboards Share blackdeath187 January 17, 2010 8:34:08 PM This was an older computer..One day computer just shut off by itself. Could not get it to power up?? Switched power supplies to a different one and this is where the craziness began. If the computer has been sitting for a few hours it will start to boot up for about 20 seconds then just power off completely. A quick restart will now only boot for 10 seconds.... maybe then again just shuts down completely? I am thinking an electrical issue? But where? MB?? i have removed every connected peripheral but doesn't change anything? Any Ideas? Thanks...Oh I have tried different HD but still does the same exact thing.
