    It sounds like either a faulty psu or mobo problem.

    Try another psu first and see if that helps.

    possible solutiuons to "no power up"

    12v 4 pin ATX connector is not plugged into mobo, this would make the unit not boot and not beep. and have consequently no video

    ram is lose, but normally it should beep several times to inform you of this. if not beeping then all i can assume is its the PSU

    video card is lose, but again it should beep saying its lose

    try another PSU, and check your main 24pin power connector and 4 pin 12v connectors are firmly in and around the right way

    i have tried to change the PSU but still no luck would it be the motherboard?

    if its still not posting properly, then next parts to check are CPU and ram. if those dont fix it, then by process of elimination, yes it is the mobo.

    If it says something like no signal or sync , it means the monitor isnt at the appropriate resolution.(800 x 600..etc)
    That happenned with my cousins computer because he changed the settings to a setting his monitor couldnt handle. Try using another display on your pc , try using one of the ctr monitors since those have a better time with different display resolutions. If you use the faulty pc with a diiferent monitor , and it works, try changing the display options to a setting which the monitor that isnt working can handle.

    Try the monitor on another computer to see if the monitor has a few "broken" wires inside the system, After my monitor fell on the floor it had a few wires break inside and couldnt work so I had to get a new one

    Also I agree with howard, It might be a PSU problem... Tell us the specs of your computer and the volts / watts of your PSU ( Powersupply )

    Hope I helped :)
