I'm not totally sure if this is a video card problem but I'm at a lost for what else could be causing this. Specs: MB - ASUS P5N72-T Premium LGA 775 NVIDIA nForce 780i SLI ATX Intel VC - XFX GeForce 9800 GX2 1GB Power - Antec TPQ-850 850W Processor - Intel Core 2 Quad Q9300 Yorkfield 2.5GHz LGA 775 95W Quad-Core OS - Windows 7 Ultimate 64 bit At first my monitor just wouldn't come on until the windows login screen came up. It would stay off all the way through the booting process. I didn't mess with it because I've had so many problems in the past I was just tired of ****ing with it especially if it was still working. Lately, in the middle of videos the monitor would unexpectedly shut off, this last time the entire computer seemed to shut down in the middle of a video. Now I can't get the monitor to turn back on, even at the login screen. Any idea as to why this is happening?
