Your system has no paging file or file is too small...

I have a client who has a Dell Dimension 2100 system with
Windows XP Home installed. Son does extensive downloads
of music and programs and system was infected with
W32.HLLP.Handy which completely filled the hard drive (40
gb). Norton Antivirus 2003 was installed, the system
cleaned and all seemed well but the client then reported
an error on startup that "your system has no paging file
or the paging file is too small..."

When you start Windows XP it goes normally to the logon
screen (they have 3 users) when you click a user to logon
you hear one low beep, there is visible access to the
hard drive which then stops and the profile does not load
until you do Ctrl-Alt-Del after which it immediately
loads but generates the page file error message. After
logging in to the 1st user by this method you can then
switch between users without problem

Any suggestions to correct this problem are appreciated.
If we go into the page file settings through My Computer
we also get an error message when we try to access the
advanced tab that the file is in a temporary location...

Any help is appreciated.
