Ok
Have set up the administrator account as above.
I can do all the admin type things through this login but cannot do it through my normal user account. I tried setting up a password for my original account but it makes no difference, how weird is this. I can do all I need but i have to switch accounts for admin rights, its doing my nut in. I knew i should have stuck with Vista, it may have been long winded but at least it did what it said on the tin.
Have checked for viruses etc, but nothing shows up. Problem now is that I have no idea when the problem started as i only noticed when i tried to install a game. Until then i had no problems with any installs????
HELP!!!!
