Hello, my brother recently got some components for a good price but now faces a problem.
After installing everything and plugging PC through HDMI its says no signal on monitor and can't get to BIOS.
Motherboard has 4 ez debug lights and goes through the 3 but the BOOT light stays on.
Both display and HDMI are tested to be good.
