2 Monitors
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.

in response to ded9, u are so right. In a sequence of steps, I plugged the cables to each outlet in the pci card. Monitor 1 worked fine, but not Monitor 2. Of all things I overlooked the power supply, Monitor 1 had full supply, but Monitor 2 was on standby. After hitting all the buttons on the monitor 2 it still failed to come to full supply. Then I plugged the power cable to another outlet on the same UPS, still the same result. After sleeping over it, I tried changing to a different power supply, and voiila, the power came back in full force. And that was the problem. Now both monitors work. Thank u to everyone for your inputs.
thank u everyone.
Thank you jegajothy, the PSU I would have considered only when adding a video card to an OEM system, but since a monitor uses an external power source I had not factored into the equation that all were connected to a UPS.
And that had lowered the power outage!!
That is a new one and will add that to my knowledgbase.
Thank you for sharing it
Good to see you resolved it too
All the best Merete

I tried a system restore to a day back, and when the problem still continued, I tried a restore a couple of days back, and it still does not display the 2nd monitor.
A check on the control panel under Display says that it did not detect the 2nd monitor. I tried switching the ports too, and the result was the same.
Can this be that the ATI graphics card dropped dead on me? If this is so, can u please suggest a good graphics card that is compatible with my Dell Vostro 220, 64 bit, windows 7 prof. Thank u for your inputs.
