EDIT: So after trying out the GPU that causes the BSOD, i got immediately it again.
First after starting up rig, my rig freezed up, and had to PSU restart, then second time i got a BSOD - System Service Exception
So i guess i'm fucked and its a faulty GPU, right ?
yup most likey i had this on two of my rigs, had to
pull the trash gpus out
