I have been following this thread since the mem=nopentium did not completely solve my problem afterall. I went to the ftp site with the fix and downloaded it. Actually I could not download it from the main site and had to search for a mirror for it. Anyway it downloaded a textfile. I am just a newbie with no programming skills, so I have no idea what to do with it. I would love to fix this instability problem as soon as possible. Could anyone help me with this? Thanks for all of the help. It is too bad that there is such a problem between Linux and amd. Will this be resolved with mandrake 9? Sincerely, Marcia
