Question Nothing will show on my screen

[Arcanite13]

My PC was working fine until last night. I turned it on today, it turns on but nothing will show on my monitor. It just says no signal. Also my keyboard won't light up but my mouse does which is weird.

It would be a great help if someone knows how to fix it.

EDIT: I have a very low end PC, here are the specs
CPU: 2.3Ghz Core 2 Duo
Ram: 4 1GB DDR3 sticks
GPU: ASUS ENGT GEFORCE GT 220
Storage: 250 GB

I hibernate my PC alot too.

Update your post to include full system hardware specs and OS.

Doublecheck that all cables and connections are fully and firmly in place.

Try another known working monitor on your PC.

Try your monitor on another known working PC. Determine if the problem follows the monitor or stays with your PC.

If the problem stays with your PC then try the using the motherboard's built in GPU (video) port if available.

However if other components are not working it could be a PSU problem. Do some testing to narrow things down.

I checked all the cables, they're all in place. My PC was somewhat dusty so I cleaned it off. Didn't work
