Vista x64 random BSOD

Was wondering if anyone can help me with my sister's computer. She has been getting the dreaded BSOD at random although when i've been over there and try to download and install some windows updates it pretty much does it every time. The information it gives me in the report is below. Can anyone shed a light on the cause of the problem. She is running Vista Home x64 and has 4GB RAM if this helps. Thanks.
