i just build my first new PC. but my graphic card (GeForce GTX550 Ti Direct CU Top) did not detected by my OS. I cannot see it n the device manager.
I had try re-install my OS. I had try disable the on-board graphic in device manager. I had try update my BIOS revision. All cannot work!!!!:-(
For one thing strange is that i try to change the primary display in BIOS from auto to PCIE and save it before exit. But when i re-login again to BIOS. It show back the setting to Auto. cannot understan why.
Anyone please help me to sovle my problem...
