Recently I have built a prototype system (RH7.2)(2.4.19)(Duron 1300)(MSI KT3 Ultra2)(250MB DDR SDRAM)(30gig Maxtor 7200 HD)(TNT2 PCI Video Card)(D-Link Lan cards). I had the same type of failure that your having and it was driving me nuts. My servers are in a 19" rack cabinet out in the garage. As you can imagine during the hot summer months the servers take a beating out there. However I do run every type of cooler gadget I can get my hands on...even HD coolers. Believe it or not they work great out there inspite of the heat. In my case I had to determine if the CPU was locking up, or if the MB, or something else was overheating. I ran a heat test on the DURON 1300. I put a variable powersupply on the CPU fan and slowly starved it for air to see if I could duplicate the problem that I was having. The Duron 1300 locked up at 60 degrees C. Even on the hottest days I was not exceeding a CPU temperature of 50 degrees C max. To make a long story short, my problem was due to a motherboard failure. I traced it down by using some component cooler. I replaced the MB .... problem solved. I don't know about the Athlon processor but the Duron runs extremely hot. The run of the mill CPU cooler down at the computer store just will not cut it. I am running a copper heatsink CPU cooler now with a high speed fan, heat pipes, silver grease, etc. Even on the hottest days I don't exceed around 42 degrees C. It would be interesting to know what temperature your CPU is running at! I bet that the Athlon would lock up at 60 degrees C. If you have a good CPU cooler that would be almost impossible to accomplish inside your house with the AC on. Good Luck, Bill KJ6EO
