In my opinion...none of you know how to update Mobility drivers. That is the problem. You can not update the Mobility (laptop) drivers without updating the Intel drivers first. If you don't have Intel drivers, then you have on-board AMD graphics and the installation has to be done a certain way. There are so many similar posts...and you read none of them?
Instaling/uninstalling graphics drivers
NOTE! Certain laptop configurations are not compatible with AMD's Mobility Catalyst™ Driver.
AMD provides graphics drivers for most laptop brands and models for the Mobility Radeon™ HD series of graphics cards.
If the AMD Mobility Radeon Driver Verification tool reports that the hardware is incompatible, then the notebook manufacturer is the exclusive provider of the graphics drivers for your notebook. (GPU-28041)
Sony, Toshiba, and Panasonic will not accept generic drivers. Get drivers from manufacturers support site.
Laptops with 'switchable' graphics must use manufacturer supplied drivers.
Did you try to roll back the drivers in 'device manager'to the ones that worked?
Did you do a system restore to a point before you messed up the drivers?
Did you install the graphics drivers furnished by your laptop manufacturer for your model laptop...from their support/driver section?
Do you know what dual/switchable graphics are?
As far as the different version numbers....the m200 series cards are all re-branded ....as Levono, or Google, tells you. So when you use 'generic' drivers, you get the generic name.
