Are you referring to a Laptop?
If so, you have to download the Graphic drivers
from laptop manufacturer website!
Seeing your sig.system (why run that top-notch stuff on Windows 7 32bit?)
Love to find out reason, as I'm still on 32bit socket A!
Is it to do with gaming or some sort of compatibility with older progs?
(I'm waiting for updated USB 3.0 motherboards with SATA 600 & proper Wireless N chips(non draft'N') etc)
If you are having trouble with "XFX ATI HD 5750
- HAH, it's brand 'new' technology so you suffer the consequences!
(till they sort out the problems with the drivers etc)
