Have you made sure the display cable from monitor is plugged into the back of the graphics card and not behind the motherboard?

Also try reseating all the power cables to the motherboard and graphics card.

Hi @rianthelion ,

Have you got a speaker connected to the motherboard?

If not connect a speaker to the motherboard's speaker header pins and check if there are any beeps on startup

JFP2 connector :

pin 1 Speaker -ve

pin 2 Buzzer +ve

pin 3 Buzzer -ve

pin 4 Speaker +ve

What type of keyboard is connected PS/2 or USB?

Hi @rianthelion ,

Try disconnecting/removing all except PSU, RAM, keyboard and monitor from the motherboard, i.e. barebones PC - no HDD, no ODD no GPU card etc and check if you get display and can get into BIOS OK.

Found the problem! The motherboard don't have support for 9th gen Intel prossesor you need to update bios first. Buying a cheap celeron so I can uptate bios. Thanks for your help!
