So i just got my PC back from being fixed (cpu cooler broke) and now first time plugging it back in, it won't detect on either monitor that anything is there, it also won't detect my keyboard and mouse plugged into the back too as they won't light up, was wondering if anyone might know what this issue could be?

I've tried plugging both monitors into GPU and motherboard slots, and my mouse into my front USBs but that doesn't light up either, i looked to see if there's a loose cable unplugged but couldn't see any and then made sure to push everything in that i could incase it was slightly unplugged, not sure what to do if anyone could help that would be great

May sound dumb but have you checked the psu switch is on?

Resetting CMOS

:one: Shut down your PC and unplug the power cord from the wall.
:two: Locate the CMOS battery (see the image below). On some motherboards, you may have to remove the graphics card in order to access it.
:three: Remove the CMOS battery from the motherboard by pressing down on the clip and pulling the battery out.
:four: Hold down the case power button for three seconds while your PC is unplugged.
:five: Install the CMOS battery back into the motherboard and plug the power cord back into the wall.
:six: Plug in and turn on your PC.
