So for the past couple hours, I had been smelling the burning plastic/electrical fire smell. I kept going around my room, checking my laptop, my lamp, the fan I have running, etc, and couldn't figure out where the smell was coming from. Last hour, my desktop computer froze 3 times, and subsequently, I had to shut it off and restart it. While I was doing work. The 3rd time I just gave it a couple minutes since I figured it may be slow, and then it went to a blue screen. No, not the BSOD, since it was a solid blue screen, that flashed and moved between several shades of blue. After checking a possibly faulty connection (which is not the case, but I had to check) between my computer and my monitor, I shut it all off. I then checked the desktop computer itself, and traced the burning smell to the power supply, the large box at the top of the computer right where I plug the power cord into. The thought has come to my mind that something may have shorted out. Thoughts?
