6850 Radeon Hd not detecting

[Temuulen]

Hi, i am new to this forum and today i bought a Radeon 6850 for my hp pavilion. I installed the card into my computer and the fans are working and its turned on, but the computer says unable to detect? what do i do

Have you installed the current GPU driver?
Did you allow the BIOS to choose the GPU?

I am not sure what u mean by gpu driver, but i did try changing the bios video output. I tried installing but it automatically installs the drivers for my old video card radeon 3200. Im not sure what i have to do to make it detect the 6850

GPU... GRAPHICS PROCESSING UNIT...

In other words the graphics cards drivers.


You need to Uninstall the old Radeon 3200 Drivers first, from with in Windows. Helps to use a Driver cleaner program to uninstall the old drivers.

Something like Driver Sweeper works fine.

Phyxion.net - Driver Sweeper

Install that, run it, and Uninstall the Radeon Display Drivers, and Catalyst Control Panel first.

Shut down windows after it uninstalls it.


Before you do that though, Download the latest Radeon Drivers for your version of Windows.

(Windows XP? Windows Vista? Windows 7? 32-bit or 64-bit?)

AMD Graphics Drivers & Software – Download the latest drivers for your graphics products

Save the drivers to the desktop, or a folder where you can find them easy enough.

After you do that, then follow the steps above for uninstalling the old drivers.



Shut off PC.

Install new Video card.


Connect power supply to Video card.


Connect Monitor to New Video card (Not onboard video output)


Make sure you didn't jar or tug any other cables in the case loose, or any other components. Turn the PC on.


Boot into Windows. Windows may need to install and run its Default VGA Drivers first, let it do so.

once those are loaded, then find where you saved the latest AMD Radeon Drivers & software.

Install the new drivers, let windows reboot if necessary, and then load windows again, with the new drivers, it should detect the new video card, load with the new drivers, and load windows, and you should be on your way.
