When i had Redhat Linux 8 it reboots by itself. Now i have Redhat 9 and it does the same thing. I was running apt4update. I left it on over night because i had 51 files. I woke up this morning i get the login screen so logged in and enter my password. I ran apt4update again. I went out to the store this morning. I came back and it was at the login screen again so i say screw it. I just logged into Windows and i making this post. Has anyone ever had this problem before and knows how to fix it or had a similar problem?? If you do please reply back. Thanks guys.
