  1. My monitor and computer shuts down after approx. 20 minutes. I have narrowed down the problem to the digital cable; if I unhook that cable, the computer will stay on. Once I hook in the digital cable to the video card, the computer shuts down after approx. 20 minutes. Help, please.

    Get into the power/ display settings and reapply them. What Operating System are you running?

    OS is Windows XP

    I have re-applied the display settings several times via Windows....not bios.

    I have narrowed this down to the DVI cable. Computer will boot and stay on, but as soon as I hook up the DVI cable, it shuts down within 1-3 minutes.

    Can you try using another DVI cable?

    Yes. I will try that next.

    I hooked up the monitor to an older computer, using a VGA cable.....and it worked fine without shutting down after 2 hours.

    So, a new DVI cable might do the trick. Thanks.

    New DVI cable doesn't help.....still shuts down.

    New video card doesn't help.....still shuts down.

    Any suggestions? Thanks.

    Nope....it is apparently not the PSU.

    What next?
