Now that people are starting to fill their motherboard RAM slots to capacity
and RAM is getting faster this is a common problem. It's most likely not a
Vista problem but a motherboard problem. When I upgrade RAM now I always
remove the old RAM and install all the new RAM from the same manufacturer
purchased at the same time. It seems many motherboards are very sensitive to
RAM timings when fully populated. I've seen problems with RAM from the same
manufacturer, with the same part numbers, but purchased six months apart.
You can try playing with RAM settings in the BIOS. Try running the RAM at
the next lowest setting than it is rated for. I still think you will have
problems because of the different timings.
