Once its rebooted it seems to fail to even reboot correctly…starts as if it's going to power on then shuts down as if there isn't enough power to get it going. Then cycles round like this…PC will eventually boot after a number of attempts but is then problematic until I switch off for a while.

I have tested running 512mb … 1gig, 2 gig and 3 gig memory….The only other things I can think of is a graphics card issue or over heating?

I am thinking a power supply issue here but don’t have any spares to test this…before I buy a new one can anyone suggest anything I can try to diagnose this a little better?

it's most likely a heat issue.. Fans are not working properly and computers are smart enough to shut down to avoid overheating. If it's a memory issue you should see the bsod..
