Windows 11 boot loop
Hello, I tried to turn my PC on and it just kept turning on and off without showing any display, this is an old PC that's been working fine. I tried to access the BiOS but it wouldn't let me. I saw online that taking the ram out and putting it back in solves the issue. I tried that, the machine stayed on but the display was not showing up. Somehow it reverted back to the boot loop. As I was looking for the CMOS battery (which I still cannot find), I saw that there is a red light on my motherboard, the light is for VGA. Is my PC toast?
