Hi Howard, This is another message just after I posted the previous one. Everything seemed to be working fine for about 15 minutes and then when I was trying to do things which previously made the hardrive to spin, the computer crashed. I couldn't read everything on the blue screen but it was something about conflict of memory with BIOS. I turned the computer off manually and restarted with only 1GB RAM and for safety reason removed all the changes. Well, if there is anything I am missing please let me know but I would probably continue to work with the spinning hardrive rather than being scarred from what can happen next. Thank you very much. Danny
