My relatively new laptop (2 months old) isn't detecting my graphics card that game with it, a Radeon HD 6470M. When I originally had it I was able to play games, mainly league of legends, on the highest settings. then the graphics slowed down substantially and recently i found that in my device manager, the radeon hd card that used to be listed isn't there anymore.

so far i have tried installing several amd applications that i thought might help and tried to install the drivers for the card but it wouldn't allow me to since the computer can't detect the card. any suggestions?

also here are the specs to my computer

The fact that your device manager shows only Intel graphics seems to indicate either:

1: The Radeon Graphics are turned off - check for a key combination or BIOS option to disable/enable the ATI GPU. This might have a name that indicates a low-power or long battery life mode. I know some Toshiba models do have a key combination to do this. HP documentation I've found seems to have little information about BIOS settings or low-power modes.

2: the Radeon Graphics have failed. As caperdog suggests, this would require service attention.
