Fixing my motherboard.
So, my son and I updated an old Dell Vostro 460 computer with a marginally better video card and some extra RAM a couple years back so he could play Subnautica, and we were very excited that we got the game working, but then after a year a year or so, it just stopped. First I replaced the CPU, after doing a jumper test on it and it failed, but when I installed the new one, and turned it on, the fan would turn for a second, then stop, then turn again, then stop. I tried removing each component one by one to see if any of them were creating the problem, and nothing changed. I was obsessing. I scanned over the motherboard a few times with a magnifying glass, and I finally found something that looks like a damaged component, but I don’t know how to figure out what it is. I am not a computer guy, but I want to try to replace this component on my own with my very old soldering skills. Assuming this is the component that has caused the computer to stop working, how do I figure out what it is and where to get it? I know this is a very old and weak computer, but now it’s personal. I posted a close-up picture I found of the same motherboard online and and put an arrow pointing at it, and then a pic of my motherboard with an arrow to show where it is. It’s supposed to be a solid black square, but on my computer, it looks like the black plastic has partly disintegrated and there is exposed, coiled wire. With the magnifying glass, I think there is a 49 beside the component. If I could upload a pic, I would. I’d love some wisdom. Thanks!
