That means that the PC is not starting, probably a bad motherboard , bad PSU o a different hardware fault.

Let me know if the computer has power.

    If the computer has no power at all then it is a faulty PSU.

    If the computer starts up but you have no signat, Try first unplugging the power cable from computer for five minutes.

    If that does not work , then it is an hardware fault, either the motherboard, or another hardware part is faulty,

    The technician will try first removing one of the RAM modules, and start the motherboard with a minimal set of devices (no drives etc.) only CPU, FAN, 1 module RAM, PSU, and if you want switch connection on MB.

    Troubleshooting may be complicated, try unplugging first.

    The problem is clearly in the computer not starting up at all or the power is unplugged.

    if all cables are correctly and the computer is getting power, and the computer doesn't turn on, The problem maybe a broken power switch, bad motherboard or powersupply.

    If you open the computer, check the small wires going into the front panel and that they are connected to the motherboard, Next I would suggest to try another powersupply and possibly get the current powersupply tested with another motherboard.

    IF the current powersupply works and the computer wont turn on even with a new powersupply the issue is in the motherboard.

    test the powersupply first and report back and we can continue.

CPU ON WITH NO SIGNAL TO MONITOR


Make sure your monitor has power and that the VGA cord or USB cord is properly connected. If your monitor has power (power light is on), disconnect the VGA or USB cord from it, but leave the power on. This will tell you if the monitor is working as it shold display a message like self check or no signal detected and then proceed to display a screen saver. If not then I'd suspect your monitor. If the monitor is ok, then try a different cable between your computer and the monitor. If that fails, then your video card may be defective.

alot of motherboards use shared memory for display meaning that if the memory cards lose connection no video.
take memory cards out of the computer and clean the gold contacts with pencil eraser and try rebooting the computer to see if you get video if not try 1 memory card at a time to see if there is a bad stick of ram causing it not to show video.

When you say "When I turn on the computer the monitor acts like it is getting no power", do you mean the light on monitor doesn't come on or it does and it states it has "No Signal"? If it says no signal then it is receiving power just no signal from computer. What kind of connection is it? Digital(white) or analog(blue)? Is the keyboard wireless or is it PS/2?

If the keyboard isn't wireless and you're plugging the monitor in correctly I would say it's a power supply issue. Try changing the outlet you're using and/or bypass the surge protector to plug directly into wall.
