OK, so my computer was working fine one day but then it just decided not to work. My computer was on but there was no video. So i got a new video card still the screen was black. Nothing! My power supply was making a wierd noise so i thought that it gave to much power to the motherboard and fried it. So i got a new motherboard. So that came in and i threw out the old one and hooked up the new and i still had the same problem. No video. So i put in a new video card again with the new motherboard and still nothing. So i thought that the only thing it could be is that the cpu broke. I was wrong again. I got a new cpu and i still have the same problem. So now i got a new power supply, motherboard, videocard, CPU, and my computer is acting the same way it has with everything in the old. It powers up, hard drives work, fans work, everything works, but on my monitor, all i see it a blank screen. I even checked it with another monitor. NOW WHAT IS THE PROBLEM!!! I am out of ideas. Anything would help. PLEASE!!!!!!!!!!!!
