[quotemsg=16098197,0,331249]is it a new build??? if it a newer gpu see if there a bios update for the mb to rule out a bios bug. check inside the pci slot for bent pins or dirt. [/quotemsg]
The gpu is a gt 530, and nothing is in the pci slot and I tried 2 different slots.
Specs of the build it doesn't work in:
evga gold 750w psu
amd fx 9590 cpu
Gigabyte GA-990FXA-UD3 ATX AM3+ Motherboard
seagate 250gb hdd
1x8 ddr3 ram
zalman z5 case
