Did you upgrade just the CPU or did you upgrade the mobo as well? If you didn't upgrade the mobo, I presume it ran fine with whatever K7 CPU you had on there before. If you did upgrade the mobo.... What chipset is the CPU running on? Are you overclocking? If your motherboard is an Abit, there's a good chance that may be at the root of the problems....Abits aren't known for their stability especially with the Via chipsets for K7 CPUs. Abits usually lead the pack with RMAs. I only ask these questions b/c I've found most Athlon stability problems have more to do with the chipset/particular mobo the CPU is resting on than Intel CPUs. Of course, that's just my gut feeling. > -----Original Message----- > From: tclug-list-admin at mn-linux.org > [mailto:tclug-list-admin at mn-linux.org]On Behalf Of Jay Kline > Anyone have any hints on this?
