I was on my computer writing a paper using Microsoft Word and looking for information on the internet when my computer screen went blue and showed a 'stop error'.  THis is the third stop error that I've recieved, but this code and the parameters were different than the rest.  Please help! 

I search microsoft help for my specific stop error and all the parameters, but that did not help. 

Error looked liked this:  Page_fault_in_nonpaged_area

Stop:  0x00000050 (0xFFFFFFD9, 0X00000001, 0X8054954C, 0X00000000)
