That information is a little thin to base any opinion on, care to provide us with a little more information, like the make and model of your rig, the make and model of the RAM that you are trying to use.
If your using a module that's only 128MB I'm guessing that you are using an older computer, like PC100 OR PC133?
normally BSOD (blue screen of death), relates to a graphics card or a RAM issue, so please can you tell us the make and type of RAM you have please!
(i have experienced many BSOD, too many to count! :D)
