Ok. I apreciate all your advices.. most of all telling me to replace hardware. I will try to ... starting changing memory. I have to tell you that I love Linux, but sometimes I lose my temper with it. I have dual boot ( RH and Win98 ) and my Win98 is much more stable than RH. They use the same hardware for 3 years (or more), and RH is the only one that hangs ! Strange because it suppose be Win98... :-))) Thanks again -- Psyche-list mailing list Psyche-list@redhat.com https://listman.redhat.com/mailman/listinfo/psyche-list
