I have 7 identical systems. all with identical MoBo's SCSI hard drives and RAM. One machine reboots frequently with 5.3 where with 4.9 it "never" rebooted. 6 machines are fine. 1 reboots. I changed memory sticks. (which incidentally always pass an extensive memory test). I even changed the power supply on the computer. The last thing I am going to change is the MoBo. Perhaps it has some timing issue discovered only with 5.3. Luckily when I needed 7 MoBos, I purchased 8 and have a spare. This is mystery, because as I said, 4.9 worked fine on this machine. regards, Jim
