Quick, complex question

[KhakiHat]

SO, recently I helped a friend finish a PC build and now it has me stumped.

 

After everything was installed, the PC seemed to be working fine until a few hours it had been turned on. It has some how developed a few issues the longer it was turned on.

To boot the PC for some reason the boot process would halt at an error menu, not detecting any sort of keyboard or mouse and to get past this, you had to swap the keyboard USB location to another port and it would boot past that screen and start detecting the device. That was the first large, strange issue I had noticed. A day goes by and then the PC boots, but then a few minutes after the PC is on, it black screens, shuts off and then tries to restart itself, though only to a black screen.

 

Also I should mention my friend somehow let a drink condensate near the PC allowing water droplets to get inside the fan grate. A large measure of droplets landed directly on GPU. I had to take it apart to complete dry up the water, using q-tips and patience, removing the shield from the top of the GPU, drying underneath and inside the PCI port. After this water incident, the PC was returned to it's former working condition of oddly working USB ports. 

 

The PC is now stuck in a perpetual motion of either booting to a black screen or booting with the strange USB trick, staying on for a few minutes only to shut off trying to restart itself with another black screen.

All drivers are up to date. I haven't tried flashing the bios but have tried removing the bios battery to no helpful avail. 

 

Anyone have any thoughts on what could be causing this? Faulty motherboard(Likely), water damage, overheating(?), suggested reinstall of windows 10?

Accidentally posted the topic without finishing typing, it's been updated ':P

 

I tested the GPU on another known to be working motherboard, outside of the USB issue, I know the main black screen issue stems from the GPU. Hopefully an RMA works out.
