Hi all,
I was having a problem where the screen was randomly freezing up within about a minute of bootup. I replaced the heatsink and PS and everything seemed to work ok. Now after the PC has been on for a while it seems to just either shut off or restart

. If it shuts off I have to wait a while and play with the on\off switch on the Ps for a while before it will boot again. I am running an athlon 900 with a cooler master heatsink\Fan and a 400w ps I checked the temp of the processor and it was 45c the system temp was 33c. Does this sound like a bad ps or heat sink not doing its job?
Thanks,
Jutah
