Ok, I recently got a computer off of my grandpas rental trailers porch. 2 actually. Together, they had everthing needed to run. Today, I finally plugged it up and found that it had an unactivated XP on it. I took my OEM Dell XP OS and it said that I had to activate it withing 30 days. Not knowing it was OEM, I tried and the phone machine said they didn't recognize it. Now, I would like to know if I could obtain it for really cheap, or free? Also, would it run ok due to the fact that the computer has 256MB Ram, with a Geforce Mx400 (Microsoft)? Graphics Card? I am afraid that to much ram could cause glitches, etc.
