re: Mandrake 9.2
Just a thought, since Mandrake is complaining of a possible hardware error...
Maybe you've got some bad RAM somewhere?
I'm not sure how much RAM you have but if you've got enough to spare you might try each memory module individually...or, if you've got a willing friend, try his/her RAM in your machine.
I've heard that bad RAM can be kind of weird like this. That is, another OS may run happily forever with it but when an OS (or a program) tries to use the bad RAM in just the "wrong" way it will cause errors.
