I am having a very annoying intermittent issue with an older PC not powering up. The machine failed and would not power up. The power switch did absolutely nothing. Thinking this may be a PSU issue, I hooked up a known good unit and the PC powered up and ran perfectly. Just to be thorough, I hooked up the old power supply and tried to power up the system. The system came up and ran as it should.
I returned the PC to service where it lasted about a week. The system locked up and would not respond to any inputs from either the mouse or KB. It would not reset or power off using the switch on the case either. Once I pulled the AC, the machine then refused to start back up. The odd thing is, once I pulled the 20 pin and the 4 pin power cables and reseated them, the machine powered back up.
I am leaning towards either a thermal problem with the CPU or MB or perhaps a bad cap on the MB. A quick visual scan didn't reveal any leaking or swollen caps. Just wanting to get some extra input before beginning to replace parts.
Specs on the system are:
MB: Intel D845WN
CPU: Intel P4 (not sure of the speed)
PSU: EMACS 300W AX2-5300FB-S2(V)
System built: 12/28/2001
Thanks in advance for any help that's provided.
