it could well be that the GPU is faulty, but there's some other things
you have connected both pcie psu cables and not just one right? if so, try different pcie psu cables. one of the cable connectors might be faulty and resulting in not enough power getting to the GPU
the original BSOD might have left something iffy in windows. unfortunately, the only way to know for sure would be a fresh windows re-install
other option is... do you have access to another PC you could try the GPU in?
Thanks for the quick response
I have tried using other PCI-E power cables, didn't change anything
If I reset windows and keep my files would that maybe work?
I have a friend coming down later, will try the GPU in his PC and post results then
