No signal on monitor
So, I just step up my pc and everything. Everything light in my pc, all the fans are running, but the keyboard, mouse and the monitor are not working…… any ideas?????
It sounds like the PC is not passing POST (power on self test)
What are the RAM specs?
Try connecting a system speaker to the motherboard to check for any beep codes on startup.
On Asus motherboards:
No beep from the speaker check that the CPU and memory are installed correctly and there's no oxidation on the connection parts. If there is any oxidation, try to wipe the oxidized part with an eraser. If it still cannot be turned on properly, clean it with contact cleaner and re-install.
1 long beep followed by two short beeps indicates a memory problem. Check that the memory is correctly installed.
1 long beep followed by three short beeps indicates a graphics card problem. If the graphic card needs an extra power supply, ensure graphic card has the power connected to it.
Here’s an image taken from p.1-15 of the user manualthat shows where the speaker connect to on the motherboard. There is also an image that shows the kind of speaker that you can connect to the header pins

There could be a problem with your graphics card. Make sure all the cables are connected to the moniter properly then restart your pc.
