I am running a K75SA with a 1200 ghz Athlon T-Bird processor booting into WinXP. It ran stabily for two months with one Micron 128 MB of DDR266 module. I replaced that with a Micron 256 MB DDR226 module and encountered a problems. When I arrive at the WinXP login screen and type in my password... my computer suddenly reboots while I am typing or when i press enter... or when I move my mouse. For a second before it reboots I see Windows flash an error message but its impossible for me to read a word of it because there it reboots too fast. When I reseat the RAM the problem temporarily disappears for a few boots. I heard a fvew months earlier there was a noted isue with this RAM module. Please advise.
