One day my Computer just started making a 10 second repeatedly short beep, without stop, then after 10 seconds it's rebooting then doing the same thing over and over again.
 


Thanks, tried to switch the RAMs then it would start without any beep codes, but now my monitor just view "No signal" then "Entering sleep mode":

Didnt work with the single RAM.
It seems like nothing is working, while on, the USB aren't on, and seems like the monitors arent aswell.
