Hello everybody, i have been looking around the support knowledge base at SuSE i am almost convinced that the reason why the system reboots unwantedly without no apparent reason is a BIOS or hardware issue. The are some lines in the system log that to a newbie like me dont look good at all, here they are: Aug 2 20:28:20 linux kernel: VFS: Disk change detected on device fd(2,0) Aug 2 20:28:23 linux modprobe: modprobe: Can't locate module block-major-80 Aug 2 20:28:23 linux last message repeated 15 times Aug 2 20:28:23 linux modprobe: modprobe: Can't locate module block-major-104 Aug 2 20:28:24 linux last message repeated 15 times Aug 2 20:28:24 linux modprobe: modprobe: Can't locate module block-major-105 Aug 2 20:28:24 linux last message repeated 15 times Aug 2 20:28:24 linux modprobe: modprobe: Can't locate module block-major-106 Aug 2 20:28:25 linux last message repeated 15 times Aug 2 20:28:25 linux modprobe: modprobe: Can't locate module block-major-107 Aug 2 20:28:27 linux kernel: VFS: Disk change detected on device ide1(22,0) Aug 2 20:28:27 linux kernel: VFS: Disk change detected on device ide1(22,64) I think its more of a hardware issue my PC is a: CPU: PIII 1.0 Ghz Mainboard: Gigabyte GA-6VXE7+ RAM: 512 MB SDRAM HD: hda (win 98 SE)= Seagate 80Gb ST380021A hdb (linux)= Seagate 40 Gb ST340014A Graphic card: Nvidia GeForce 3 Ti 500 Sound card: Soundblaster live 1024 NIC: SMC 1244TX So, my question is how would you go around looking for hints as to what is going on? and please if you can point out the problem i would very much appreciate it. All the best, Gabriel
