Dear USER,
I own a successful computer repair business. I may be of some assitance to your issue.
Here are the instructions:
1.) Leave the Radeon xPress 1150 in place. You can either select not to use this, or use double-display features.
2.) Now, turn of your PC.
3.) Install the PowerColor Radeon X1650.
4.) Plug your PC into the OLD DISPLAY ADAPTER.
5.) Once you login and get to your desktop, right-click and choose Properties where their is no icons.
6.) When the display properties comes up, choose the 'Settings' tab. This is where you will see two boxes, once saying '1' and one saying '2'. Select '2' (or 1 depending on which is the correct adapter) by clicking on the '2' in the box.
7.) Down towards the Cancel and OK buttons, it says 'Use this device as my primary monitor' and it should be unselected. Now, go ahead and select it and choose 'Apply'.
8.) Now, you must unplug your display from your old video adapter, and plug it into the new one. Video will then reappear.
I hope this helped your dilema. E-mail cline_tech@yahoo.com for more help, or if this solution worked for you!
Sincerely,
CLINE Tech Primary Technician
