My Asus P5K Pro won't boot.
- When I connect the power
- Powerled on mainboard lights up normally. (doesn't flash, just turns on)
- When I press the power button;
- fans spin up
- powerleds on the front do NOT light up (normally they would)
- no beeps
- no screen output
I have managed to boot up a few times after taking out mainboard battery and clearing CMOS RAM. It looked like each time when I changed a random settings in the BIOS (like boot order, or time) I would get the same problem again.
But now I can't get it to boot up, even after clearing CMOS RAM.
I have tried to replace the mainboard battery with a new one, did not help.
Has anyone experienced this before? Any ideas are greatly appreciated!
UPDATE: I don't feel it has anything to do with the power supply. Disconnecting HDD, DVD, USB etc. did not change anything. Also, after clearing CMOS RAM, I have been able to work on this computer for a few days with all devices attached.
UPDATE: I have also tried to remove graphics card and memory, still no beeps.
UPDATE: FIXED: Swapping out the PSU seemed to do the trick, allthough seeing the circumstances this didn't seem likely. After swapping back to the old one, PC didn't work again.
Let's see if it holds up.
