Computer unstable with two gpu's?

ROG STRIX Z390-E GAMING Motherboard

Updated Bios

 

I have my program / computer crashing narrowed down to two gpu's in use at the same time. So either my motherboard or bios is causing my issues

 

One gpu works fine. PCIE cables are good. Drivers good. Bios updated. 1000W power supply should be sufficient.

 

Has anyone had their computer run bad after adding a second gpu? Is it an issue with this MOBO? Halp!

 

Thank you!

1000W PSU means nothing without more detailed information. What PSU is this? What GPUs? Any risers or other adapters being used?

I do not have any risers or adapters being used. One of the blue screen errors fixes was to "reseat the hardware". Possible the lower PCI slot is busted perhaps.. I think I'm pretty sure I have it narrowed down to the bios or motherboard not liking two gpus.. regardless of whether they are both rtx or not. Plus I did update the bois so I'm assuming it has to be the motherboard / PCI slot

 

Basically it crashes programs or freezes the computer under any difficult load with two GPU's. One gpu handles much more, however two gpu's still have better render times in a light load scene.. A heavy scene crashes with two gpu's.. Really tough road narrowing it down as far as I did and was hoping some poor sap had experienced similar issues
