My friend recently unplugged his PC to rearrange his room and then plugged it in an hour later and it did not turn on at all. I came over to his house to check it out and tried all the basic things like different outlets and all sorts of things like that. Then I took out his GPU, still didnt work. No lights or not even the slightest bit of sound comes from anywhere in the PC. I have dealt with issues similar to this before and tried everything I tried then and it still didn’t work. I just don’t understand how it could work and then not work when plugged back in like an hour later. He did not open the case or touch anything inside at all. Anyone please recommend me ideas as to what it may be. One thing I did notice about his PC is that it is dusty as hell. I’m not sure this has to do with the issue since it has been that way for a while but I do know dust can affect it. Anything to help please let me know. Thanks.
