I posted a question about this same computer previously. I thought this problem was solved but not so. We have a dual Pentium 4 HP 4000 with a Seagate SCSI drive. The computer began to lock up and sometimes allow reboot and sometimes not because it would recognize the hard drive sometimes and sometimes not. From the answers to last question I posted I thought we had it fixed. However, shortly after, problem began again. The machine is running Windows 2000 server. When it began to lock up again, it would give message that event log was full. I made some changes to the way it was logging which seemed to prevent the logging error message but the machine would still lock up after a period of operation of less than one day. I have obtained another SCSI drive and am now trying to install and boot from that drive to see if my problem is in the old drive or with some other part of the machine. I have removed the other drive and connected the new drive. I attempted to load Windows 2000 Server on the new drive by booting from CD. During setup process, I pushed F6 and loaded the SCSI driver and Windows proceeded to load until point of first reboot during installation process. After the reboot, the computer could not seem to find the new drive to continue installation and failed to boot. This computer has built in SCSI controller, but I have very little SCSI experience and am not sure how to configure all aspects. I currently have the drive set to ID 1 by use of jumpers. I did not know if it needed to be set to 0. Any help on any of the above issues would be appreciated. I need to get this machine back up and running or at least determine why it will not run. Also, I would like to know how to disable the lengthy RAM test at boot up. I have enabled the Quick Boot option in the Phoenix BIOS but test still runs.
