I recently built it, it was working fine until yesterday it freezed, then I tried to turn it on again, the monitor would display: no signal. Have tried removing the ram and also plugging again the gpu. I also put the cpu again and applied thermal compound again, for a moment that worked. Today I got up and tried to turn it on, it was the same situation. My mobo has dual bios, so I changed to the backup bios, it worked. When using the main bios, the leds mark the cpu as the problem, I wanna know if there is some way to revert that, since I would like to use the main bios, to have the other one as a backup. Thanks in advance!
