No signal in monitor after reboot (error code 02)

Hello,

After rebooting my computer there is no signal in my monitor. I've checked the monitor and the cables and both seems to work fine. The Q-Code LED in my motherboard (PRIME TRX40-PRO) shows error code 02, which according to the manual means "AP initialization before microcode loading), bu I'm not sure if both issues are related. I've also tried to use antoher monitor, but the "no signal" problem persists. 

Thank you

yeah seems your motherboard indicates you a problem preventing you from booting, i don't know about the message but this is what has to be checked
