    I upgraded my PC got a new graphics card, new ram and a new power supply. I switched everything out and I get no signal on my monitor and when switching to my on board card I get no signal as well. Fans and systems powers on my monitor shows no signal and goes back to black screen.

    I need help I don't know what do to do. image.jpg image.jpg

    I'd start by removing the sand box from the computer, that's way too dirty to allow the computer to run properly. That heat sink is filthy and will cause the CPU to overheat and throttle down performance or even shut down. A can of compressed air will fix that.

    Aside from that you don't have the 4 pin power connector for the CPU and that absolutely needs to be connected.

    The video card may also have power connectors near the back that need to be connected.

    It's a power cable from your power supply that must be plugged into your motherboard. It's the beige square plug with 4 sections at the top right hand of the motherboard. There will be a matching cable coming from the power supply that needs to be plugged in there.

    Looks like you may have unplugged a SATA cable or power cable from your hard drive.

    Let's see another photo of this area inside the case.

    Unless the cooling fan unit was removed first, it's pretty difficult to remove ALL of the dust and debris from the processor's heat sink unit.
