Suspected faulty power supply, want outside opinions.
Very recently (Two days ago, in fact), the newer of my two computers died. I was playing the Left 4 Dead 2 demo with one of my friends and it shut itself off. Repeated presses of the power button did nothing. After figuring out that it wasn't a power outage, I kneeled down next to it to inspect it and smelled smoke coming from inside of it. So, after going through my obligatory "OHSHITOHSHITOHSHITOHSHIT" moment, I opened it up and could find nothing wrong.
So, based on a review from the same Newegg page I ordered it from, I suspected that it was a faulty PSU. After speaking with my friends, one of them showed me that the same (Or, at least, a very similar) power supply was priced at $15 on Newegg, so I've not much reason to doubt them. I've ordered a new PSU and should have it in a few days.
However, I'm not an expert with hardware failures (Thank God), so I want some opinions from a third party. Did my computer turn into a brick because of a power supply failure or something else? I can see no damage to anything in the computer and the power supply was warm for several minutes after the failure. It still won't turn on, of course.
Edit: I'm still not going to get used to these forums' code. Links fixed.
