Windows 7: BSOD 0xA0000001 whilst gaming

Hi all,
I'm getting regular BSODs whilst gaming and occasionally whilst running other applications, with the code 0xA0000001. I have listed my specs and attached the ZIP file as requested by the forum. I'm running an overclocked system (4.8Ghz), but I've taken it off to see if it's the source of the BSODs and that doesn't help. I've used DriverMax to update my drivers. If you could help me that would be great.
Cheers
