My second system is a P4 desktop. It was working fine, no symptoms of any problems - then yesturday it would start briefly and then completly shut down after about 5 seconds. No POST beeps at all, just shuts itself down.
Here's what I've done:
Switched the PSU with a known good one, same problem.
Removed video card and all RAM, unpluged power from all drives - same problem.
Is there anything besides an overheating CPU that can cause this? Both fans spinup at startup without problem.
All ideas welcome.
More aboutsystem starts shuts seconds later
Could be MB but definitely sounds more like the CPU.
How would I go about confirming the CPU (without having a replacement to use)?
