No screen / Black screen

[A Gamer]

Soo, sometimes my system startup with black screen / no screen. I have to hold the power button and then the system startup with screen. This doesn't happen often but it still make me question.

The even log:
Kernel-power ID: 41
After that it said: unexpected system shutdown

Kernel 41 might mean my system is without power for that moment but i am certain that is not it.
My computer runs fine at heavy moments. I did run memtest and other heavy benchamarks.
This only happens when i shutdown my computer and has never happend when my computer was running.

Hope someone can help me.

If you stress tested your cpu, gpu and memory and still found nothing, then something is happening with your boot sequence. You could try repairing the boot record:

You could also run a general system check like so:

You don't have any usb drives or anything plugged in into one of your usb ports right?

check that you have the newest 1d bios. the 1c has video card bug fixes. in the bios under primany display set it to peg/pci not auto. see if the error stops.

Repairing the boot record fixed it.
