No picture on monitors

  1. HI all,

    I'm having problems with my PC.

    When I switched it on a couple of days ago, I only got video through to one of my 2 monitors. After a crash, I rebooted and got no video on either monitor, however, I left the PC running. About 4 or 5 hours later, the monitor flashed up the start screen on one monitor and I got the windows is configuring updates message. It rebooted a couple of times, and on one occasion It started displaying on both monitors. While these updates were sorting themselves out, we had a power cut. I now have no picture on either monitor.

    I started the PC up again after the power cut, and I could access shared folders across the network, so the PC was working, just not displaying video. Now, I can't even access those shared folders.

    Any suggestions on how I go forward from here? The obvious suspect I guess is the graphics card, but I had a similar problem with a PC a few years ago, and that turned out to be a problem with memory

    Thanks
    John

    What I would do in your situation:

    IF I have monitor working in BIOS, then try bootable RAM test, memtest86.com. Run overnight.

    IF NOT, try another GPU.

    Once I have a basic working system (using different GPU or one less stick of RAM, etc), MAKE BACKUP and make a recovery disk.

    Then check for error reports: Device Manager and Event Viewer (google for 'how to').

    Let us know how it goes for you.
