Hey yesterday I was on my PC for a while. I went downstairs for a second and when I came back, it was off. I unplugged, then replugged it back in, and the green light came on, but it didn't start up. I smelled a wierd smell from it as I looked inside to see what's wrong. I took the main connecter from the power supply, and took it off of the motherboard, and the green light shut off; I put it back on, and it came back on, but still didn't start. What do you suppose is wrong with it? Any help is appreciated.
