New PC Windows 7 freezes on start up

Hello,
Ive just recieved my pc, its windows 7. Started it up and seemed to run ok, installed set point 4.72 for vista just for the mouse mx510, on the logitech forums they all said that it was ok for windows 7. About 20mins after everything froze up, I rebooted & now it freezes on the start up logo screen. The repair option I couldnt see if it done anything as it froze on that too. Got it started, uninstalled set point restarted as promted, froze on restart, couldnt get past start up screen so I started in safe mode set point is still there, tried to uninstall & its saying you cant uninstall & got an error code, looked it up and a fix was system restore, tried that & froze on the restart for that too.. Overall the pc was only on for about an hour & a half from when I got it, so Im unsure if its a faulty PC or something to do with set point. I have the recovery disc, would that be an option? I dont want to ring the help line incase they blame the set point drivers.
Thanks for any help in advance

 

Thanks very much for your help, we took it back to factory settings, updated windows, restarted & got the freeze up again. Phoned them & told them the "basics" & they are going to replace it. With how quick it happened yesterday & with installing set point it really threw us what was the best & safest option. So again, thanks for your advice.
