Hello, turning to the toms hardware community to help me with my nearly 4 old build.Never had any issues with this build over the years until about a year perhaps a year and a half ago I had a very small amount of water drip into my case from above while it was on, I took everything apart to dry including dissembling my gpu and let it dry for at least a week.

fast foward a week, I decided to put the build back together fresh paste on the gpu and cpu no luck on getting it to fire up so I let it sit for about another month before trying to boot it up again and strangely enough it fired right up and has given me 0 issues up until a few weeks ago it started gradually before now getting worse, It wont boot to bios constantly I have to sit there and restart it over and over again and pray its going to boot into bios when it finally does it always gives me the 'american microtrends error screen' I have to reset my clock n all that jazz to get back online, this happened randomily before it started not booting to bios display at all. now it happens everytime I manage to get it to display.

At times when my computers completely off my led keyboard will stay lit up, when the spill happened I think it was mostly into my cpu heatsink n maybe sprayed out from the fan n there was a few wet spots here n there on my motherboard but nothing else appeared to have any water on them.

I really want to believe I just need a new motherboard which is no big deal maybe my bios is all messed up? I've taken the cmos battery out n left it out for a while the machine is unplugged.
I've tried different ram configurations etc I use silverstone cable extensions for all my psu cables.
Now I just leave my computer on to avoid having to go through rebooting my computer 30 times to get it to actually display, I've tried taking my gpu out and plugging in hdmi to my mobo still the same issue.

anyways thanks anyone who takes the time to read this jumbled mess.
specs:
Asus z97 sabertooth mark 2 board
i7 4790k
2x 8gb corsair hyperx 1866 ram sticks
evga 980 sc acx 2.0
evga supernova 850w psu

With water damage anything the water touched can be damaged. The extent of the damage varies from accident to accident. When I spilled coffee on my desk and into my PC, only my video card was destroyed and the motherboard survived. What I would do is take the RAM, video card, and hard drives out of the PC and test them on another PC to see if they work. If you do not have access to another PC I would have a shop test your parts for you. If they all work I would go ahead and purchase a new motherboard. The CPU is possibly just fine.
