To Begin: Computer Specs Dell XPS 400 Specifications: (http://support.dell.com/support/edoc...0/sm/specs.htm ) Radeon HD 4800 I am visiting a friend in west virginia and he purchased a 1gb stick of ram with the incorrect pins that could fit his mother board. I removed his elder ram stick ( as all of his 4 slots were full with 512 MB sticks ) and noticed it was the wrong size. I reinserted the original RAM . I loaded windows and windows no longer was showing 2 gigs of ram ( the starting point of RAM available ) and now only shows 1.5 GB , which indicates ( obviously ) that the computer is not detecting the RAM stick i removed and reinserted. I tripple checked that it is in right and I just cannot figure out why it is acting like this. I am in desperation to fix the issue because now I have slowed down the person I am visiting's computer ( as his Windows XP takes up 1600-1800 MB of ram in casual use ; so now it is freezing ). If someone could give me several routes to advice, please do so. I will be checking the forum frequently as I am trying to fix this as soon as possible.
