Hey guys, I've just decided to start using Ubuntu again, first I'll give you my problems(s):

I'm dual booting along side windows 7 (I used wubi)

My computer is dead slow running ubuntu, which is strange since I have 4gb of ram with (I believe) a 2.1ghz processor (64 bit).

I tried playing some games to see if they would be slow too, and they are, so I thought this might be a driver problem, I've gone into driver settings and it says "no propriety drivers are in use on this system" also there are no drivers available to download, it's just a blank space.(I don't know what drivers I need either)

I don't know all that much about Linux, only used it briefly before, now I'm in a bit of a pickle.

Any help would be amazing, thanks for your time.
