So I was playing a game (Diablo 3) and then all of a sudden I hear a loud pop, it made me jump I'll admit, but there was no smoke afterwards from anywhere in my computer but there was a faint smell that was off, hard to explain though it did smell SORT OF like something had burned but I don't know, I'm unsure on that one. So I try to see where the smell was coming from but it's impossible to tell because inside the case near my GPU, the smell is there and then the same smell inside the power supply though they're both not strong smells, it's a faint smell and they both smell more like dust rather than a burning smell.
My computer is not stuttering or chugging at all so that is another plus, maybe I was hearing a pop from somewhere else in my room? I'm not sure but I don't want to risk that. My computer still works 2 days later and over the course of those two days, every boot up has been just fine with no problems, same load time and all, I'm browsing the web as usual but I have not started up any sort of game, be it Diablo, Aion, Star Wars, Starcraft, WoW etc. because I'm worried I might make it MUCH worse. Any way to tell for sure where the pop came from? Is this a serious issue I should be really careful about?
