I have a DELL Vostro 410 running VISTA with an ATI RADEON graphics card part# 7120036300G installed. The computer also has on on board VGA port which was not being used. The graphics card has 3 ports on it. I have attached 3 photos showing the front, ports and back of the graphics card. The computer was previously using another monitor using the DVI port on the graphics card. This worked fine. I changed the monitor [for personal reasons] to one that used the VGA port, which as explained above was not on the card, but on board. When the computer was started, it came up with an error while in the boot stages indicating F1 to continue, F2 to enter setup. Under one of the settings it showed that the computer was using the PCI for video. I changed this to onboard, hoping that it would now recognize the monitor plugged into the onboard VGA port. But the error appeared again. I then went into the Control Panel and brought up the card in device manager and disabled it, thinking that now it would have to see the VGA port. Of course this was not the case. Now the computer boots to a black screen with a box saying out of frequency. I removed the card and started the computer and got the same error. I tried another monitor and got the same error. I took a similar ATI card out of another computer I have and installed it and got the same error. When I boot the computer, I can hear the Windows welcome tune indicating that it was at a login screen, but all I had was a black screen and the error out of frequency. I tried to access the menu on the monitor, but it would not appear. Finally, in a moment of probable stupidity, I reset the bios back to default settings. This didn't appear to affect the computer good or bad.
How do I gain access back to this computer?
