When starting the computer on the motherboard, the cpu, dram, vga, boot indicator lights up one by one. But at the end, when the computer starts, the boot indicator does not turn off. The screen works, I can go into the bios, but that's all I can do. After the gigabyte inscription I can either go to the bios or the computer reboots, and so on and so on. I think the cd drive is broken.
