I was watching expendables 2 (which is obviously the reason for the fails) when there was a loud sdjfswldfka;sf noise (kindof like a crackle as the sound cuts out unexpectedly), and everything froze. Si i powered it down by holding power button, left it a little while and attempted to turn it back on, only to get nothing showing on either monitor. They aren't receiving picture at all. I tried putting a different graphics card that we know works in my PC, and still same error. I put my graphics card in a different PC and it worked fine. The only thing I can think of is that it's the motherboard. Does anyone have any different opinions? If it is, it looks like I'm in the market for a new PC.
