I have a big problem.  My son appaerntly has a virus on his Dimension  4700 desktop.  We get a warning message from McAfee that the ciomputer is not protected by when I try to fix it I can't get to the McAfee site on his computer.  IE says page not available.  I tried some other virus and registry clean up software without success.  Long story short -I want to format the C: drive and re-install the WIndows XP.  I tried to find out how to do that in the on-line manuals = no luck.  looked all over the Dell web site = no luck.  Called tech support and they REFUSE to tell me where to find it unless I pay them $100 even though they siad it is on the Dell website.  UNFREAKINBELIEVABLE.  Can some point me to where I can find these instructions or tell me how to do it?  Needless to say when my son goes to college in the fall he will not be carrying a Dell laptop with him after this treatment. Thanks, Gary
