This is my first post here, i might missing some details. When i was doing things on my PC, my computer just suddenly froze, my cursor still can move around but cannot open or run any programs. After waiting for a short time i restart by PC then it put me to BIOS setting and i got stuck there. I tried methods like replug the HDD and SSD but nothing helps, i notice on my motherboard (it's a Gigabyte B360M Aorus Gaming 3) in the corner has 4 LED lights and the light stucks on the bottom right of those 4. I cannot find what cause to problem and what to do next.
