Hi all, So I was shutting down my computer today, and just as I hit the point where it was about to turn off, I had a blue spark come from the case (clear side so I saw it). I'm assuming that it was my PSu, but what do you think? Could it have fried my mobo too? I'll try a new psu as soon as the stores open tomorrow, but I really hope that it wasn't my motherboard too. Funnily enough, I was running windows and about to install gentoo. Guess microsoft didn't like that idea?
