Had 2 times power went out on me while on pc, first the soundcard got fried and the second time I do not know what happened? Its an older P2 450Mhz 300WTS ATX, now I go to turn pc on and it will go and start up but if I shut it down or re-start it it will not go, I can hear and feel action in harddrive for a couple seconds and then dead, nothing. Wait a few days and start it up and it goes until I re-start or turn pc off. Thought it was dead or dying PSU got a new one and it was not that, so now I am wondering if it is the mainboard or the processor that is dying? Some1 got a way for me to check which it is? thanks for any info on this!!
