Optimal method for sanitizing a motherboard (to address a potential short-circuit issue)
I've checked the setup and everything seems fine. The dust buildup is likely causing intermittent issues. You can spray the contact cleaner generously on the board, including the PCI-E slots, and let it dry. Alternatively, use a cotton swab dipped in alcohol to clean the affected areas. This should help identify any shorts.
Household dust mainly consists of dead skin that doesn’t conduct electricity. I’d suggest reattaching components or giving each connection a proper shake. For older hardware, adding a fresh CMOS battery could also help.
Varies by maker, but earlier models often needed a functional battery to start. I’ve noticed this on most original equipment. A few were only a few years old, so it might not be the main issue unless you're using a non-OEM setup. It’s something that can usually be resolved with a quick adjustment.
They last approximately ten years when your computer is linked to a power source providing 5V standby power, which replaces the battery to maintain CMOS settings and keeps the battery idle. In storage, it lasts two to three years at most. A battery is inexpensive; just replace it when needed. To clean the motherboard, use isopropyl alcohol—any concentration works, but ensure it reaches around 97% purity before wiping. Place the board in a plastic container and thoroughly soak it in alcohol, shaking it well. You can also gently brush surfaces afterward. After a short period, remove the board and let it dry in a warm area; the remaining alcohol will evaporate quickly. If the alcohol is below about 97%, wait until the residual water evaporates, which usually takes around 30% of the drying time.
Hey guys, just a quick update: I tried again after just blowing the dust off and it worked. Although I found out the problem wasn't the dust nor the battery, it was the GPU not being fully slotted into the board. I have it on top of a piece of fairly sturdy foam (for height) so when I slotted the GPU, it flexed a bit and didn't go all the way in. I figured it out because I tried slotting it again but this time I put my other hand under the foam/board for extra support and then the system turned on just fine
