I have a 2 1/2 year old ASUS Sabertooth X58. It does get through POST.
i hear a single beep when the Boot Up LED turns ON which typically indicates succesful POST.
There is display on the screen and I can enter the BIOS menu. But cant get beyond that.
PC keeps restarting. Replaced PSU with new one and also made sure HDD is fine on another PC. Tried all combinations of the 2 RAM sticks. Reset BIOS. Still no change. Beginning to feel something is wrong with MOBO or CPU, but no component failure signal during POST.
Kindly help me out.
