PC crashing when trying to boot

[Nertballs]

i just completed a new build yesterday, and windows was working perfect. it did a few big updates today, and since it's going through the load screen, but then just crashing out (no blue screen just blank)
i tried rolling back, no good, tested memory there was no issue, reset bios, still nothing. it had been running which is bugging me!
i tried to reinstall it, but it's doing the same!! please help!
