So I came home from work sat down powered on my laptop and it instantly restarted afterwards my rtx 3070 wasn’t detected anymore so I went into the bios and in chipset changed it to direct graphics and boom black screen 

I’ve tried to reset the bios blindly by pressing del repeatedly then f3 enter and then f4 enter 

external monitor 

disconnecting the cmos battery and waiting a few minutes 

reseating the ram 

and holding the power button for 15-30 seconds pressing f4 

nothing worked and I can’t find any way to contact support since my warranty ran out a few months ago
