There are a series of Q-LEDs top right of the MB just above the 24pin plug. Do any of them light up and stay lit.
They consist of Boot, CPU, VGA and DRAM which light up then go out if all is OK.
Report that before we move on?

None of them light up

None of them light up

You may then have a corrupt Bios or a cold boot bug.
Try clearing CMOS and if not successful then flash your Bios to latest version using your rear IO panel and a USB.
I can help further if you need to Flash your Bios.
Are you able to access Bios?

I have cleared CMOS but haven’t tried bios flashing it yet
I’m not able to access the bios although my motherboard has a bios reset button on it

There are a few other things that can be a cause of your problem however I doubt that to be the issue cause of the age of your system. They are a failing or dead CMOS battery or failing PSU.

Flash the Bios to Ver: 1004. and the Bios Renamer tool which will rename the file to RB550FGW.CAP.
Download the file from ASUS support to your system then use the renamer.
Transfer the renamed file to a USB that is formatted to FAT32 single partition and no other files on the USB.

Power down your system so there is only power to the MB and insert the USB into the correct USB port in the rear IO panel. press the Flash button till it begins to flash and let it load. Takes a few mins and if it stops and flash button is continuously lit then something is wrong.

Refer to page 2-12 of your MB Manual should you be unsure about anything which also shows the correct usb port to use for flashback.
