System is powering up, but no display whatsoever. No blinks/power on the keyboard. CPU, LAN Card, GPU are all up and running.
Beep - This feature was somehow disabled to fix the power button on Cabinet coolermaster CM-690.
The onboard lan card got bad and use to cause BSOD on Windows XP and numerous problems on Windows 7. So it was disabled and PCI Lan is in use. So after installing the LAN Card(Yesterday) the system booted up pretty well and both Windows XP and 7 ran pretty fine with no problems at all.
Now in the morning its refusing to wake up. It got started once but just after the initial boot screen, it went dead again(no power in keyboard, monitor but CPU, GPU and LAN were all on.
I am guessing maybe the Motherboard is the problem, or well there can be some issue with the start button.
Any ideas? Thanks.
EDIT: NO POST or OS Boot screens.
UPDATE: Came back from office couple of hours ago and the system is backup and running fine for 3 hours now. I think the PSU is bad. If there was problem with MOBO the system wouldn't have started.
