My OS is win 7 Prof 64 bit and I use a Dell Vostro220. I have a ATI Radeo HD4600 Series pci card for my 2 monitors, and they were working fine for a long time. I had been doing some spring cleaning of uninstalling programs that I had never used using the Revo Unistller program and also I ran a check disk and also using CC Cleaner cleaned out the registry that ha broken links. Under Device Manager, Also defragmented the disk after all this maintenance. I see the card and it has no exclamation mark. After all this maintenance, now my 2nd monitor does not detect.
Under Control Panel under Monitors, I see that the 2nd display is not detected. I have not toiuched the original wires and the pc was never moved. But to make sure I unplugged and plugged the wires into the card again.
Can a guru help me fix this problem please. Thank u.
