    Does the hard drive come on?

    Use a multimeter on the connection the goes from the PSU to the motherboard and see what you get, it could be the PSU that is knackered.

    But then you could be right with your diagnosis if the PSU is ok.

    the psu is ok because there is power to the motherboard i dont know if there is power to the hard drive but even without the hard drive you would still get something come up on the screen right?
    all the fans etc are going but the monitor is getting no signal from the pc.

    first up.. disconnect EVERYTHING from the motherboard and start over.. reseat the memory and processor and if there is a VGA card reseat that too and boot up with just that. If you say the mobo is getting power (im assumuing the mobo lights light up?) then it still could be the the PSU or the mobo so the next thing is if u have a spare PSU try it because i seen PSU's light up mobo lights but they dont have enough power to boot up the PC!:dry

    You have no beep codes? First thing I would do is try a diffrent monitor and plugs that come with the second monitor.

    It happens with me sometimes with certain games with copy protection. I fix it by resetting my bios. Simple as that really. :blink

    no unfortunately there are no beep codes, zimbo i have tried everything you mentioned except for swapping the psu, i have an old pc which i took over to swap some parts in and out but mine is so old that nothing is compatible all different connections etc.
    How do you reset the bios?
