I had a similar story. I set up a home pc for recording tv and hooked it up to the main entertainment system. I built it on a budget so it did it’s job but later on as we switched to more HD content it struggled occasionally.
I went off to college. My mom noticed the fan noise was increasing and found it distracting. She wrapped the pc in a couple of blankets to cut down on the noise. When I came home the thing was in danger of burning down the house and the video card had failed.
I am not sure if the following is true or one of those stories that gets recycled.
While I was working at Best Buy - the Geek squad told us a story of an older Lady who brought in a computer wrapped entirety in plastic saran wrap, to prevent the virus from escaping the computer and infecting people. She thought it was okay as she containing the virus and continued to use the computer before it turned off and didn't turn on again, which is whys she brought it in.
On the Pentium Overdrive! days, a guy came to my father's shop complaining that the computer wouldn't turn on. Turns out that he had installed the process in a different orientation "to see if it would go faster". Spoiler alert: it didn't.
Neither the CPU nor the motherboard failed (nor did the fancy overdrive socket). Once the CPU was installed correctly, it worked again.
My 'best' related Best Buy story (well, Future Shop a decade ago, but it is/was the same company) while working in the ConnectPro department (name for Geek Squad at Future Shop, all the same tools and procedures):
A person who had purchased a laptop a few hours prior came back into the store furious because the device shut off and wouldn't turn back on. I pressed the power button and it flashed indicating the battery was dead. I connected the laptop to power and told her it needed to be charged. She then threw a retail tantrum because the salesman had apparently told her it was wireless.
I think this really says more about a lack of basic science education in high school. People plug 1800W space heaters into $4 power strips and cause fires. I think by the time you graduate you should at least be able to understand that watts of electricity are the same thing as heat.
