My Asus monitor keeps saying VGA No signal and eveything is plugged in

[nate62]

So I recently bought a CPU cooler for my Asus desktop computer cause my old one broke. I plugged it in and everything else back and as soon as I turned on my PC, everything seemed to work, except my monitor. Every time I turn it on all it says is "VGA no signal" and then it goes to black and I have the VGA cables plugged in as well. I'm not sure what might cause this issue, if its my desktop computer, I've had for at least 6 years now or so or maybe something not plugged in correctly even though everything should be. If any one has any solutions or any ways to fix this please let me know thanks!

My Asus Desktop is a ASUS Desktop PC Essentio CM6730-06 Intel Core i5

Are you sure your computer works at all after the repair you did? A non-working PC will "output" same to the monitor.

Turn your PC, wait five minutes, and press CapsLock or NumLock buttons on the keyboard. Do the LEDs go on?
