Hamluis, as you know, I've been treating this as a hardware problem. However, Everything in my system has repeatedly tested good under a number of diagnostic utilities. This problem just appeared one day about a week after I replaced a memory stick that tested bad. The new one worked fine and tested fine. All was well for a week or ten days. As a precaution, I have ordered a new power supply in case there is a voltage fluctuation. I am currently having to turn the power on and off a number of times (two, three or even four) to get the system to boot up. It seems to run fine as long as I am working, surfing etc. Once It becomes inactive (for a random number of minutes) it may reboot itself or go into a type of hibernation (with all fans running). Screensaver only works sometimes and even then, it will go into a sleep mode. When this happens, I have to do a hard reboot in order to start back up. Windows has worked fine for quite a while, so as Chewy suggested, it could have been an update that fouled things up. I have kind of suspected BIOS problems for a few days, but am not well versed in the setups. Your article helped, but It's a socket 370 board and the last bios updat was in 2000.
