Why is my computer not showing BIOS?
If the motherboard or the CPU’s power connector is plugged in wrong or faulty, you won’t be able to boot to BIOS. The motherboard has a 24-pin connector, so make sure it’s plugged tightly in the right place, and there are no signs of damage on the cable itself. The CPU usually has an eight-pin connector in a 4+4 shape.
