text: how to format hard drive of millenium computer that was upgraded to xp home.? i've formatted computers with win 98 with no problem by going to restart in dos. that doesn't seem available in xp. music, games, dvd, etc. seem to erratically temporarily stop and move slowly. could this be virus activity. i have enough memory. you need not format your entire drive just to fix the problem you're encountering. it seems that you need to update all your media drivers, that is, sound and video codecs in order for winxp to recognize fully your hardware. try to get these from update.microsoft.com, or use the driver cds which came with your pc and/or hardware components. in order to format a drive on which winxp is installed, you'll have to go into your computer setup by pressing f2 when booting up, then configuring your rom to boot from the cd drive. then when you put in your winxp cd, and restart the pc, it should restart in winxp setup mode and allow you to partition then format your drive.
