I booted up my PC for the first time this morning, I have an ASUS Prime A320M-K motherboard, and I had a BIOS setup on my monitor. For some reason I was messing around with the settings and configurations and since that happened, my PC restarted but the BIOS screen never came on. All I get on my monitor now is 'no video available'. I have tried disconnecting all the cables related to the problem, removed the little lithium battery from the motherboard, waited 30 minutes for a supposed "CMOS Reset", and im getting nothing. What is the problem? Is it my graphics card? or the fact that I changed an unknown setting which has cause my PC to not function at all?
