Kernel data inpage error

Hello,

Recently my computer has been blue-screening every so often producing the following error (from system logs). It's a Kernel in-page data error.

Fault bucket 0x7a_0, type 0
Event Name: BlueScreen
Response: http://wer.microsoft.com/responses/r...e-383fb2d35be5
Cab Id: 097855bf-4c1c-49aa-bdde-383fb2d35be5

I have followed all of the instructions given by Microsoft (reinstalling drivers, chkdsk, eventually re-freshing windows etc) but it still happens every so often.

My system is:
