Hello list, Been a loyal SuSE user for a couple years now and recently bought a used box with the intent to run it as a database server. The seller claims that it ran Linux flawlessly before he sold it to me. Well, after three complete reinstalls and one hard drive failure, I just cannot get it to stay up. The frustrating thing is that there are never any error messages when it goes down. Actually, it doesn't really go down, it just hangs. No network and no X. Reset doesn't work, holding in the power button for 10 seconds does though to restart it. What I've noticed is that it seems to happen more often than not when I am using my laptop to run a remote desktop on this box using VNC. About once or twice a day everything will stop and I'll have to go do the power button thing. Nothing interesting in /var/log/messages (or any /var/log file for that matter). Is there anything I can do to get more information? Here's what I know: Major software installed: cups, samba, nfs, mysql, postgresql, oracle (though I quit running it due to crashing thinking it was the problem), tomcat, and zope. Almost complete set of YOU patches installed except new kernel and glibc which may completely hose oracle. Previous installation with all YOU patches failed too. 512 MB memory, 1GB swap, system doesn't seem overworked. I stopped nearly all processes including cron and it still died once. I had a hard drive failure a while back so I installed on a new drive, then I put the old drive in as a slave (IDE) and zeroed it out. I don't have anything on it, but it is still on the IDE cable, could it be causing hardware problems? I also noticed that the video card fan is not always working. The box has three other fans though. Might try to replace the video card to see if that helps. Any other thoughts? Let me know what other information will help in diagnosing the problem... Thanks, Josh
