    When i try and boot desktop up the fans start and lights come on etc. however the screen dosn't display anything. I have changed the screen and the graphics card.
    I also noticed that the keyboard is not noticing as when i press numlock no light changes. Any advice you can give? :)

    Let me guess, you just turned your power off from the mains? XD

    Turn your machine on, let it boot. Give it 2 mins to get to the desktop. When it's at that point (you can't see) do this:

    Hit the 'windows' key (windows logo on keyboard)
    Press the UP arrow ONCE
    Press Enter/Return
    Press the RIGHT key TWICE.
    Press Enter/Return
    Let the machine reboot, monitor should kick in.

    This happens with older machines (like mine xD) and it usually fixes it. Is great.

    Also aye, most PSUs will work :)

    few things to try

    try removing the ram boot the system leave it for a about 30 secs power off then reinstall the ram (common problem with some abit and asus mobo's)

    check the graphics card is in place correctly (best bet is to remove is, check for dust build up on slot and on the card(check the fan if it has one spins freely)

    you said you have change screen im assuming you have check the cable too.

    if the have on board graphics (if its an older board this is more lighty) make sure its disabled

    cant help any more with out system specs

    I tried removing the ram, removing the graphics card also and blowing dust rom them.
    I was not able to try a new monitor cable though i doubt this is the problem.

    I tested the monitor on a seperate computer and so it is not a problem with the monitor.
    The psu seems fine has the HDD spins etc.

    I'm presuming that there are no beep codes when it starts up.

    If so it will most likely be the motherboard itself :mad:

    did you reboot the system with the ram out ?
    famous last words would never count it out
    even with a knack psu some of the rails might work hence some of the gear might power up, but the wattage/voltage could be screwed

    or maybe theres no case speaker :)
