I was gonna play a game, started it while on Skype with friend.

Suddenly the screen went all black and the monitor light went orange, while I smelt something burning.
I turned it off, wait a while and tried to turn it back on, it went all good, made it till the Windows 7 Welcome or whatever it says, right before desktop loading and then it went black.
Can't turn the PC on since.

Can you tell me what's the problem? Thanks
