Could be faulty RAM or a bad driver amongst other possibilities.<br />
I use WhoCrashed (<a href="http://www.resplendence.com/whocrashed" rel="ugc">http://www.resplendence.com/whocrashed</a>) to analyse a BSOD. It sometimes points you directly to the problem driver.<br />
You could also try doing a System Restore to a point prior to when the BSOD's started.

Stop 0x50 &quot;PAGE_FAULT_IN_NONPAGED_AR<wbr />EA&quot;, and always a result of a faulty driver. Details require the Minidump, as said above.
