Here's the quick of it: Perfectly working PC Desktop, I go on vacation for a week, return home and it no longer starts at all.
1. Pushing the power button has no effect on the machine at all. None. Zero. Zip. No fans, no spinning HDs, no LEDs light up.
2. At the advice of a friend, I disconnected the PSU connector to the mobo, and then shorted the green/black wires with a paperclip. I turned on the PSU power switch and voila, the fans spun up. The CD-ROM light did not go on however, and the eject button had no effect, but I assume it's not supposed to? Please note that I left everything plugged in exactly as it was when I did this test; all I did was unplug the connection to the motherboard.
3. I then tried to short the power switch pins, again with a paperclip, and nothing happened.
Any help here? It seems to me as if the motherboard is dead. But the fact that the CD-ROM didn't have any power when I shorted the PSU makes me wonder if the PSU isn't supplying enough power to the rest of the machine?
It's really frustrating to me to have a machine that is working perfectly fine, and then to come back to find it dead for no apparent reason. Cursed machines. Here are the specs in case they're relevant:
AMD Opteron 165 - OCed to 2.6ghz
DFI Lanparty UT NForce4 Ultra-D
XFX GeForce 7800 GT PCI Express 256MB
Antech 3800B
400W SmartPower 2.0 ATX12V v2.0 (Came with the case)
OCZ 2GB Platinum
74GB Raptor
300GB Seagate SATA 16mb
Thanks in advance for any help.
*Additional Info:
A couple of things I forgot.
4. The amber/yellow light on the motherboard is on.
5. After plugging everything back in and turning on the switch to the PSU, the green power light on my case goes on and stays on. The power switch and reset switch still have no effect, but the green power light stays on. It only goes off if I toggle the PSU switch. Anyone ever seen this kind of behavior before or know what it means?
