Now I need your support its been a awhile that I don't update my drivers, but here is the deal, I have HD 4670M that M stands for mobile.
No the new catalyst drivers don't work, they are only for desktops. I have tried to search newer drivers from the ATI site to no avail.
My OS is windows vista 32 bit
To whoever gets this I can offer a reward of 300.000 internet points!
