Hey guys im new the the forums and decided to make my first post. Recently I bought a computer (Windows8 Pre Installed) so i decided to downgrade back to windows7 because honestly who wants windows 8 lol. Anyway i was able to play games like League Of Legends and Amnesia and others but after going to windows7 ive been getting driver errors and display errors. I stayed up all night downloaded all my drivers and display stuff and everything seemed to be working fine but for some reason i can't play the games i used to because of my graphics card. Now I have 0.0MB Of Video Memory and not sure why. here are some of my specs

Your Win8 PC might have had AMD drivers already installed. When you installed Win7, did you install any AMD drivers?

If you didn't install AMD drivers, you should go to their website and download the drivers needed for your AMD video chipset: Link

Hello OP, need more specifics on the errors you are getting, please.

Be verbose on those.

What Windows 7 was installed, you had a full retail version available? [pirated OS: bad]

If given Windows 8 on a new PC, I would now advise keeping it, it can be made to look almost like 7 with free utilities.
[Going backwards can be troublesome finding all drivers, plus 8 is supposedly optimized, running 5%+ better than 7 on same hardware.]

The one matching laptop I found, had 7 on it, and not exactly a powerhouse computer, Toshiba playing model #'n games, so many so many C855D models for different markets I guess, all $350-$400 price range mostly.

This it?
