I have been using an Athlon 700 on an AsusTech K7M motherboard for about a year. I have 512 MB PC133 SDRAM. I am overclocking at 800Mhz. (This board is great for tweaking overclocking settings.) I have two main hard drives. I normally run WinMe and can't remember the last crash, or if I ever had one. When I pop in the other hard drive it boots Windows 2000 Pro. On occasion, half way through boot-up I get a blue screen indicating a page-fault and suggesting I disable BIOS shadowing. I just reboot and it comes up OK. I have never had a crash yet on Win 2000 but have only used it for about 4 months.
