Dell Demensions Windows XP 1 Gig ram Due to a nasty virus I could not get rid of, and I messed up my system trying to get rid of it, I did a clean install of XP. Problem #1: I am now trying to install my modem driver using the wizard, but when it gets to where I choose a com port, none are showing and the "next" button is blanked out. According to a Microsoft article, it is because all ports are in use and I need to disable one to make room for the modem. Problem is, I can't figure out what is using them. Where can I go to check and see what is on each port and how do I disable one? Problem #2: When I go to My Computer, it is showing 5 USB drives (???) and my 2 CD/DVD drives are showing as "J' and "I". I have disabled all the USB drives (is that ok?) and have gone into the drive manager to change one of the letters of the CD/DVD drive to the correct letter; however, the 2nd CD drive is not showing in the in the drive manager. It is a working drive and shows up in the device manager. What now? Thank you in advance for any help!
