I just sold my gaming computer, and the person emailed me and told me that he turned it on, and 15 minutes later it shut off. When he tries turning it back on, it keeps turning off. When I shipped the computer, it was completely fine. My guess was maybe the CPU fan fell over so it's overheating? Any ideas? I told him to take a look. If it did fall off, would that hurt the CPU? Or should it still be fine? And if it did break, would the USPS insurance cover it do you think?
