I was able to restart it this evening, the pc stayed on a whole 5 minutes before it blackout again

I looked at the system event log, the only thing it displays is the amount of memory changes from instaling and uninstaling the ram to test it

I was able to run the ram test without it blacking out, i ran all the standard and extended tests, "no erors have been found"

I turned of fast boot, i dont see anything in the setup for the beep code

i have windows xp so there is no "step by step confirmation"
