My sapphire radeon x1950 pro has two power in puts

The video processor in this card has failed. Nothing you can do, the card is dead, replace it.

Get a new Video card, Your Radeon x1950 has meeted the end of it's life cycle. Once of the capicitor is damaged. You can repair the card if you know how to solder and weld other then that, it is cheaper to get a graphic card these days.

For this card you will utilize the ATI Catalyst Suite:

To obtain this siftware, visit the ATI website by click here http://game.amd.com/us-en/drivers_catalyst.aspx

Select the Full Catalyst Software Suite by clicking on your Operating System.

After you have downloaded the software, foloow the instrctions to install.

Try updating the drivers first. http://game.amd.com/us-en/drivers_catalyst.aspx . First uninstall the previous drivers and software. Reboot, and install new drivers from the website provided. If you continue to get the red screen it is more than likely a dying video card, which you will need to replace.

its very much likely that your VC is already malfunctioning...

What i recommend is take the card out your computer and see if it boots up.....if it does boot up then you know for sure that its the card or not...if it is the card it will all depend on what sha happened to it...if it has been struck by lightening then you household insurance should cover it to be replaced if you have household cover....but if it has just started that for no reason take it to the people you have baught it from so they can do a check on the card...please feel free to get hold of me if you need assistance

make sure the driver you download is for VISTA not XP

try an earlier model of the driver see if it works OK
