[SOLVED] black screen of death

[Rover Mark]

Recently completed my first build, went well, thanks to lots of lurking on this site.
yesterday, son was playing with his VR Occulus and the screen filled with white blocks and froze.

Tried rebooting. all i can get is the MSI Bios page, then it enters a problem, repair cycle that appears to be win 10, blue screen, win10 like fonts and buttons.

nothing seems to get me past the WIN 10 or MSI try to fix stuff.

on my device management, it gives me error 43 on my graphics card.

really a noob at this .

build info
MSI MPG x570 Gaming Plus MOBO
Nividia GEFORCE RTX 2060 Super
AMD Ryzon 3600 CPU
Samsung 970 EVO SSD
T Force Vulcan Z DDR4 16G
PSU Corsair RM650
WIN10 64bit

i am at a loss of what to do at this point.

remove and reseat the GPU. Make sure power cables are firmly attached. reboot. Your HD may be corrupt so you may need to chkdsk for errors. Try resetting the cmos on your mobo
