hmm... everytime i've seen psu problems, it's all or nothing. Meaning you wouldn't even boot up. Also 500w is more than enough for your setup.... i doubt you use 1/2 of that... so I doubt it was pushed very hard. Sounds like your fan broke on your vid card. i'd bet on it. But I always lose bets so idk. Easy to check though just have the case open when it's on and take a look.
