hi i got this new pc for a friend couple of days ago. i got the parts and assembled it myself and got it runnin' cool and clear. but when i tried to install an antivirus, it took all administrative privilages from me! so i installed a new version of win xp sp2 . this time this dvd-ram didn't recognize a minus dvd! which it did before the crash. i have never ran into something like this all my life!
