I built this computer five years ago. It's in a very large tower, liquid cooled.
Recently, the liquid reservoir developed a slow leak. (I have a new one on order).
The other day, I was moving the case around to get some air bubbles back into the reservoir, and I lost my grip and the tower slammed over sideways. Since I was holding the reservoir with one hand, I yanked the power cable out of the back in case any liquid dripped on the board. Then I saw that a few tiny drops had shaken onto the board here and there. I left the computer alone for a couple of days to make sure it was completely dry. I also ran a blower over it for a couple of seconds.
So finally i decided to give it a try. When I turned the power on, all the board lights lit up, the ones that are supposed to anyway. So far so good.
I noticed the lights on the tower did not come on, including the panel lights and the cooling system. It's like the case was getting no power. I started looking for connection problems.The first thing I noticed was that the Q-connector was no longer seated correctly. That's the little harness connector where all the individual panel connectors plug in, and then it connects them all at once to the board. Some of the Q-connector's pins were bent, I suppose when the tower went over and I tried to stop it. I took off the Q-connector and plugged the individual connectors into their respective pins, but no difference. I removed the video card (the only card not integrated) and all RAM to see if I could even get a beep, but no beep. I took out the hard drive connection, USB connections, and the audio cable, so basically just the power cables going to the board. There's the big single harness and two smaller harnesses that all connect to the board.
The board has a power button and a reset button. They are lit up but do nothing.
I took the connectors off the power switch pins and bridged them with a screwdriver. Still nothing.
There are several little rubber push buttons on the board. One for example switches for BIOS1 and BIOS2, another for CMOS reset, one on overclocking,etc. When pressed, all of these appear to function by making various small LEDs light up on the board in response. There are four small LED warning lights for VGA, CPU, etc. but these are not lit up.
I removed the other side of the tower cover to look at the IC board of the tower. All the connector harnesses have clips and they all seem to be snugly plugged in.
I think that's it. Don't know what the next move is. I don't have any equipment to test the PSU or the CPU, and I don't know what else I can do to check the motherboard. Before I disconnected the external speakers, turning the PSU button off resulted in a kind of loud static pop each time.
What's the next step? I'd hate to replace the board if it's a simple fix, and I'd really hate to replace the board and find out the PSU had gone bad.
Thanks all.
