Graphic problem please help:(

[imaverygdboi]

Im on a Pavilion dm4 ,Windows7 , i5 and ATI Mobility Radeon Premium Graphics which supports microsoft Directx11. Recently when i just rebooted my laptop, the resolution was extremely large. Trying to solve things, i right clicked my desktop and clicked screen resolution. I put it at the highest resolution but it was still the same. Than an error came up saying "No ATI graphics driver is installed or the ATI driver is not functioning properly. Please install the ATI driver appropriate for your ATI Hardware.I also can not adjust the brightness of the screen. I am at a loss of what to do. Please, please help me. Thanks in advance.Also when i do a factory restore it is still the same.

Reboot again and see if problem still exists. If not, will need the exact make and model of your laptop for the correct driver.
