I’ll be straight with it. I’m a smoker, I smoke inside, I have a PC that is also inside. I want to clean my PC thoroughly to buy it a few more years. I know about the q tip method, and the compressed air, and general methods of cleaning out gunk and junk from PC parts. But this boy is way too gunked up for a regular cleaning. So, I reckon, the easiest way to clean it is to dunk the dirtiest parts in a bath of isopropyl alcohol. I was considering acetone at first, but it’s way too strong of a solvent, and alcohol should be better at dissolving organic residues. Is this a good idea?
I hereby submit this query to the council, and await judgement.


Thanks! The whole PC had a time (when its age was ~20 years) where it still booted, but with reset BIOS settings, followed by a time where it doesn’t boot up anymore. So I believe the most likely thing is that it leaked and caused damage. Retro computing community thinks that the most likely cause is battery damage.
Here is the exact model from someone else: https://theretroweb.com/motherboards/s/msi-3121-v3
Battery (top-left) already removed, but it shows that this one has leaked before as well. When you look closely, you see battery residue on the nearby 8-bit ISA (?), so it must have leaked a lot at some point and been cleaned up. Unfortunately, it came with a notorious Ni-Cd Battery; even for its time not the best.
You’re welcome! Wow I forgot about those batteries, they were the worst! That’s an awesome board. I hope you are able to repair it.
