I have a friend that has a Compaq Pres. 3100 desktop running an AMD processor, Windows XP Home Edit. 5.1.2600 SP2 Build 2600. We uninstalled some un-important programs and the computer would not finish starting up. It did the Compaq screen then the Windows start up screen then a VERY fast blue screen and started all over again. We started it in safe mode & went back to a date when it as fine and it's back to normal. We did this twice - the uninstalling of some programs with the same result. The programs weren't anything that he even used so I don't get that part. THEN, I installed Microsoft Office XP and the computer doesn't list it in the programs list. It is however in the 'add & remove programs' list. Any suggestions??
