no display!

[starbuck]

Parent's PC wouldn't boot the other day(they've got an xp2200 on an nf7-s board). The error code suggested it was overheating. Reset the cmos and it stopped doing it.

Had a look at the case and there was a lot of water in the bottom of it and the connections on the back(for graphics card, usb slots etc) looked a bit green which meant that water had got to them(nothing on the main motherboard, just the usb connections and the graphics card).

I cleared it all up and left it to dry completely. Got a new DVI cable as old one looked a bit green on the connections.

Strange thing is, pc is turned on and beeps once which suggests bios check is ok but the 15" advent tft screen shows no signal.

Tried their PC on my 20" dell monitor and display comes on immediately and it boots up normally.
Thought this then meant it was the monitor. Plugged the monitor onto my system and the monitor showed my display straight away.

I'm now lost as to where to go as they both work separately of each other but won't work together, even though they used to before. I need serious help.

Check the pins on the graphics card?

edit: eeh nm. if your monitor works on their PC, I dunno.

[starbuck]

yeah, they're fine as pc worked when hooked up to my own monitor

[smargh]

Try resetting the BIOS to failsafe defaults. I'm not sure under what circumstances this would lead to it working, but it's worth a try.

Also remove and re-insert the graphics card just. Probably won't do anything, but anything is worth trying.

[starbuck]

tried that, still same prob.

[peterb]

Are you using the same cable for both tests?

[starbuck]

yep.

[starbuck]

still no joy, can't think why they both work separately but not together.

[Dreaming]

is the graphics card automatically trying to set a high refresh or something that's out of range?

[starbuck]

can't even see the post screen

[Jay]

how did water get inside??

[starbuck]

still not figured that out. nothing nearby to let water get to it.

[Dreaming]

Yea, on the monitor though, is it just blank like no signal is plugged in, or does it say 'out of range'? It's a really weird issue, that's the only thing I can think of, if the GPU is trying to run outside of monitor specifications. Just out of curiosity is the system watercooled? Or did it just get watered? lol

[starbuck]

the monitor shows no signal(although as I said, when U plugged into my own PC, it worked immediately).

System isn't water cooled, it looks like water got in the back and went down to the bottom of the case, so it missed the mobo completely only getting some of the ports on the back slightly.
