I was browsing on my desktop PC yesterday and my computer suddenly shut off. So I try and start it back up and everything appears to be fine except that I can't get an image on the monitor. I know the monitor isn't the problem because I tried hooking up another one and I got the same problem. The video card seemed to be working fine when I opened the case so I don't think that's an issue. I'm thinking my motherboard just fried on me or something. Does this sound like a motherboard issue? Any way to tell for sure before I go buy another mobo?
