I have a HP DV6-6002sa laptop. The motherboard failed after one of the chips burnt out. I replaced the motherboard with one that had a slightly better graphics card onboard.

Strangely, the laptop shows up two different GPUs: AMD Radeon HD 6650M and ATI Mobility Radeon HD4200 series.

I presumed this was because the old drivers were still there. So, I did a full reinstall (Windows 7 Home Premium) but the [problem persists.

The laptop works absolutely fine although I get the occassional AMD notification.

What is causing this? Why are two different GPU's showing up? The processor, an AMD Phenom II P960 quad does not contain a onboard GPU? How can I stop this? Will this affect the running of the graphics or any other element? Has anyone else come across this before?
 
What do you mean by "full reinstall"? Did you do a "clean" install, deleting the existing partition and recreating a new partition to install the OS on? If not, I'd start there.

What is the model number of the new board? As a starting point I'd try running display driver uninstaller and then reinstalling the newest version of the device driver after a reboot.

Since I am unsure as to which is the new graphics adapter I included links to the most current drivers for both chipsets.
