My computer has been having issues recently about the monitor turning off when I'm using it or gaming on it, and now the monitor just does not show anything. When I turn it on, the monitor is blank and the LEDs on my keyboard dont turn on. The power button also stops working, So to turn it off I have to unplug the computer. I had replaced the video card and the problems with the monitor turning off still happened. I tried running it with different RAM sticks, but that did not work. my specs are:
Radeon HD 7950 3 gb
Corsair Builder 600W 80+ Bronze Certified ATX Power Supply
Intel Core i5-4670K 3.4GHz Quad-Core Processor
ASRock z87 pro3 motherboard

I think the motherboard might be the problem, but I have seen on other threads that the PSU might be the problem as well. Any help is greatly appreciated as this is very frustrating.

Hi

Problem could be power switch, motherboard or psu or something else

If over clocking cpu or ram or graphics re set to default and see if this changes things

If your PC has a reset switch as well as power switch you could swap them over and see if that makes any difference (same type of switch used even if visible buttons differ)

I assume there is a output for the integrated graphics on the motherboard so try removing graphics card and operating on integrated graphics
This rules out many high resolution games though .

Without access to spare parts difficult to diagnose what is wrong
