I spilled coffee, no milk or sugar, through the top vent of my case. A fair amount maybe 1/4 - 1/3 of a cup. I switched off the PSU immediately, wiped everything down, and cleaned any visible residue with 91% alcohol. I left it for 2-3 days before reassembling. When the I flipped on the PSU it lit up, but when I went to power it on all of the fans and lights lit up and ran for 5-10 seconds before turning off. It's been like this for quite a while.
This weekend I gave it another crack. I disassembled everything, cleaned it all again, and rebuilt it out of the case making sure everything was done correctly (this was my first build and I'm not very experienced). I tried a different PCIE slot this time for my GPU, and this time everything powers and remains powered, but I still have no image.
I've tried running only one stick of RAM in case any of the ports are gunked up and tried multiple slots for my GPU. Same result, powers and remains powered, but no image.
I haven't tried disassembling the GPU itself, would that be my next step? If that fails, what is the most likely culprit to buy a replacement and test GPU, motherboard, both?
