Hi guys i got a intermittent issue with Black screen/artefacts on boot.
It happens about 50% of the time and only when booting up the desktop (no issues when doing anything else)

Pc will display the motherboard splash then either just black screen or display random brightly coloured lines, all fans and other lights (mouse, keyboard) are on when it happens.

I've reseated the ram and gpu, updated drivers and bios and reinstalled windows.

I'm guessing it is booting to windows as if I remove the dp cable from the monitor or gpu and put it back sometimes it will display windows login screen and let me carry on with no issue.
