BSOD when GPU under load

[BigManWithSmallPockets]

Hey all, recently built a new computer and am already experiencing major issues.  I wanted to stress test the system for stability reasons, so I started with furmark.  After a few minutes my computer would blue screen, the screen would flash it so I couldn't see the error code, then the monitors would just be black while my computer ran.  If I tried to restart immediately after the BSOD it would flash a VGA error on my motherboard.  It wouldn't do this on my old 2070 and only on my 3090 TI. I also swapped CPU and RAM and the problem persists.  I plug my GPU into a friends computer with my same power supply and it ran furmark for 20 minutes no issues.  My friends motherboard is a B450 while mine is a B550. Could it be an issue with PCIE Gen 4 or just my motherboard in general? I plan on RMAing the board anyway, but would it even fix my issue? 

Thanks.

The BSoD crashdumps should be written to the C:\windows\minidump (IIRC) folder, upload them here, I'll look through them and see what's going on
