graphics driver changing

ok heres the thing......... The other day i updated my graphics card driver to the latest one offered for my graphics card of the lenovo website. I downloaded and installed the driver but when i tried to play age of empires 2 an error message came up saying "please make sure ur display driver is compatible with (some program that i cant remember)". So i rolled back the driver to my previous driver, but then all these error messages came up saying "rundll32 has stopped workin and will now close". I read some other threads and people were saying that this is cause by some files left behind from the newer graphics driver which i had uninstalled. So i read up on it and downloaded the program "driver sweeper" to remove the excess files. I ticked the display drriver and display chipset folders (as instructed from another nbr member) and removed all the files, but some were left behind. I booted my computer up in safe mode (as instructed from download page of the program) to completely removed all of files from the driver i uninstalled. I did this, restarted my computer and then tried to launch world of warcraft a whole heap of error messages came up saying "please make sure you graphics driver is connected". So i went to control panel and searched for a new driver for my graphics card (just incase it was different from the one that had started all this trouble). It found one a driver and installed it, world of warcraft now workd fine, but that error message came up again when i tried to load age of empires 2 again "please make sure ur display driver is compatible with (some program that i cant remember)". Now when i go into control panel and look at my graphics card driver, i am unable to click on the "rollback driver" button as it is greyed out.




can anybody help me
