Im using a HD radeon 6850
This has not been working at all and today is my first day of Overclocking so i was wondering if maybe the fact that i have MSI afterburner installed if thats interfering please help!
Is that no valid device found refering to the video card? the MSI Afterburner is a software program designed to help you to overclock the GPU so it shouldn't be interfering with the overclock. Do a shut down and the start up again to see if that will correct the message your getting.
