Heres the deal. The other day I went into my setting and told the computer to start shutting down my monitor after 30 min. As soon as I woke up the next morning I went to move my mouse and the computer wouldnt wake up. I pressed the keyboard and all to and nothing would happen (the monitor remained black and saying "no video". I actually turned my computer completly off and rebooted, but the monitor still didnt show anything. I could here windows boot music in the speakers but never could get the monitor to show anything. Well, I got a new computer (not because the problem) and completly forgot about my problem i was having. Well, my computer did the same thing last night and I couldnt get the monitor to show anything. I even rebooted and got nothing. I finally shut the computer down and waited several hours. Then when I turned it back on the monitor "worked". I know its not a monitor issue so Im not worried about that. But does anyone have any idea what is happening. I am using the same video card that was out of my old computer (nvidia fx5900xt). Im running windows xp on a athlon xp 3200 with 1 gig of pc3200 ram. 450watt power supply, and am not pushing the supply. Any ideas? its almost like the video card wont wake up when I tell the computer to do so, Even after a reboot!
