xp apparently not recognizing ram

[L J Morrison]

I have 1 Gig ram installed, the Bios recognizes it, on
start up it show up, however, the windows system
information shows only 512 mb.
This is affecting performance. I have already run
msconfig, and taken out all non essential startup items.
Need help.
Thanks
