My computer started showing some problems like "could not read memory from"—– something it shows blue caption with white words saying win xp has stopped working due to some problem. Sometimes it does not boot properly close and starts many times. I tried to repair it with windows cd but few files were not copied saying these are corrupt. I formatted it and and installed fresh xp then I went to Microsoft site to updated. After downloading few files it restarted and again behaving as it was doing before I installed new Xp. My earlier xp installation worked for 9 months. Please help what to do. How to solve this. Is there free software that can repair Xp? What are the indications if RAM is not working properly
