Hi, I have a strange problem. New build with 500 watt PSU (Arctic). Would POST at first but then would not, no error beeps and no video. CPU and case fans spin, power to the DVD drive.
Tried a 2nd hand 350 watt PSU (Magna) and the system would POST and I was able to install Vista.
I tried the Arctic PSU in a friends PC and it would POST and boot without any problems.
I retried the new PSU in the new PC, this time outside the case and it still would not POST.
Refitted the 2nd hand PSU and would POST and boot and seems stable.
Anybody got any idea what the problem could be
