    Hi all,

    Wondering if ye have any ideas/solutions for me. My screen won't recognise that the computers on, though the computer sounds like it's starting up it doesn't beep on start-up like normal.

    I have tried connecting the screen to another source and it works fine. Obviously this is a problem with the computer itself, but if I can't see a display I can't find out what's wrong.

    My computer only has Digital Outputs.

    Appreciate any help.
    Thanks!

    Try reseating the RAM modules, could be as simple as a dislodged RAM stick/or a faulty one, try booting off one or the other on its own if the reseating doesnt work

    When you say Digital outputs do you mean DVi (White connection) or do you have standard VGA (blue connection) or HDMI.

    Describe the Outputs on the PC are there more than one.

    If the motherboard has Video output, is there also a dedicated video card with more outputs.

    Post a pic if you can.

    The Monitor may also have different inputs, I have a monitor that accepts VGA / DVI / S-Video but you have to select the input type yourself, the button usually has an arrow pointing into a square.

    Could it be something like an overheating graphics card? I had a similar problem with an HDMI connection on a Radeon 4870, until I cleaned the crap out of it gave it a bit more ventilation.

    What version of windows, what graphics card, what make & model of monitor.

    If hearneys advice doesn't work...

    This seems a bit silly but... monitors these days are fairly complex things compared to the old days.
    Might be worth disconnecting the power for 15 seconds to reset it. Works with some Dell LCDs anyways when they get stuck in blank 'sleep' mode.

    I should explain further.
    I have the computer and the same monitor for about 2 years. This happened after I was using the computer and put it into sleep mode, when I pushed the enter key to start up again the computer sounded as if it was booting up properly but the screen didn't recognise it.

    The outputs are DVi. There are two of them and didn't seem to make any difference. To be honest I never have tried doing anything with the internal components and am a little reluctant to do it. Are there any precautions I should take?
