My computer boots fine again. The problems that are gone are: - The CMOS settings now seem to persist from one reboot to the next, where at least the minimum fan speed setting would change on me and cause an alarm to sound. - The system makes it all the way through the BIOS power up tests and all the way to a login prompt, whereas before it would stop at POST code 37, a DMA test. The things I did, which might have had some affect are - Replace CMOS battery, cleared, and reprogrammed the CMOS. - Removed a 9GB SCSI hard drive. It wasn't being used anymore, and I'd intended to remove it anyway. The first thing that got my system to boot was to take a SCSI tape drive and CD drive off of the power supply. I wanted to keep those in the system, so I removed a hard drive from the supply's load and reattached the drives I wanted to keep. The system still boots fine. I used my BIOS system monitor to examine all temperatures, voltages and fan speeds in the system. All look OK. Thanks all..... -- PLEASE post a SUMMARY of the answer(s) to your question(s)!
