problem installing games

[dtl]

Can anyone help me?
I cant install any new games on my pc.
It wont recognise games that have not been installed.
Both CD-rw and DVD-rw drives will not recognise any new game disc, they will however recognise all current (old) games and dvds etc even if I uninstall the assosciated software and try to install an 'old' game, it works.
Its as if recently my account setting on XP has become limited, they are all however set to administrator level.
This I have changed to and from a few times, to no avail.
Any ideas?
PS I have since tried restoring my settings, via acessories, to an earlier date, but this doesnt appear to help either.

Please please help!!!!

All my drives will recognise and install old games, they will not see the new games.
