BSOD randomly occuring during normal computer use

Hi everyone,

As of yesterday morning this computer I am typing from has started crashing to BSOD at (what seems to be) random at intervals from 2 minutes to 2 hours. My computer knowledge is limited and as such I am looking for any help on the matter. Attached are the files your sticky thread specifies.

Kind regards,

Jonathan

Oh, a little bit of perhaps relevant information; this PC is 5ish years old and originally had Windows XP installed. The W7 version I believe is full retail.

Regards
