    Hi,

    I've been having this problem on and off for a long time and it's now reached the point of being a major hassle.

    For months when I turn my PC on the system boots but the monitor does not turn on. When I turn it on manually it says on screen that there is no video signal. I press reset on the system and it boots. All is well PC runs fine all day.

    Now however the PC starts up, I get about 4 post beeps and the monitor wont boot. Now it can take me 10 -15 mins to get the system up. Pressing reset no longer does the trick. I've found if I turn it on and leave it for a few mins then turn it off and on again it usually boots. It's almost like it needs time to warm up?

    Any ideas?

    I've got a NVIDIA TNT card, 1GB AMD Athlon, 512 RAM, Tiny Computer.

    The thing that bugs me the most is when it does boot up, the PC is fine? if somethings damaged then why does it work at all?

    Cheers

    Neil

    Hi gromit77
    Try leaving the monitor switched on overnight after you shut down the pc next time.

    Hi.

    I can't :( if the PC isn't on and you turn the monitor on, it says No Signal and turns off

    I think the beeps you hear are those that tell you the main board does not detect a video card and/or monitor. I've seen this before and the only solution I've seen is to replace the video card. If that doesn't fix it, my experience has been that the main board is bad.

    But, before I would throw the main board out the back door, I would do further diagnostics. I would swap out parts like the RAM, disconnect the CD drive and any other IDE devices. If you don't have any extra RAM to swap out with, look and see if you have two or more RAM chips. If you are lucky, you can remove one a a time to diagnose a possible bad one. Remove all unessential add-in cards, etc. If the problem continues, then you are probably down to the board being the culprit.

    Keeping in line with the video card possibly being bad, you may want to try reseating the video card before you write it off as bad. Take it out, then put it back in. Try to boot, and see what you get.
