Almost ruined a $600 motherboard because of bad advice

Some guy on a Facebook group told me to use isopropyl alcohol on a live board to find a short. Said it would bubble where the heat was. Tried it on a Gigabyte Z790 board last Tuesday. Almost started a fire. Short was actually a cracked capacitor near the CPU socket. Don't trust random advice from people who can't spell capacitor.

and that's exactly the kind of thing that makes me nervous about DIY advice. My buddy @the_felix had a similar scare with a motherboard a few years back. Some guy in a forum told him to use lighter fluid to clean off thermal paste. Said it evaporates fast and leaves no residue. Well, he did it, and the whole board started smoking when he powered it on. Turns out lighter fluid leaves a thin film that conducts electricity when it gets hot. Fried his whole build. He still jokes about it, but that was a $400 lesson. The moral is, if someone's advice sounds too wild or they can't spell basic computer parts, just walk away.

Did you at least get a cool story out of it? I once tried to fix a monitor with a butter knife because some guy on YouTube said it would work for prying off the bezel. Ended up slicing through a ribbon cable and turning a simple backlight fix into a full e-waste situation. At least your board didn't catch fire, so that's a win in my book. The real lesson here is to never trust advice from someone who calls a capacitor a "capasiter" or whatever.
