Thanks for your reply.
I've run Verifier and have had 2 more BSODs, dump file attached
I've pasted WinDbg info below which seems to suggest it's either my Hauppage TV pci card which is at fault or the Intel 82579V Gigabit driver, I have the latest drivers for both installed:

N bytes of memory was allocated and more than N bytes are being referenced.
This cannot be protected by try-except.
When possible, the guilty driver's name (Unicode string) is printed on
the bugcheck screen and saved in KiBugCheckDriver.
Arguments:
Arg1: fffff98008cc3003, memory referenced
Arg2: 0000000000000001, value 0 = read operation, 1 = write operation
Arg3: fffff8800648358d, if non-zero, the address which referenced memory.

An expected clock interrupt was not received on a secondary processor in an
MP system within the allocated interval. This indicates that the specified
processor is hung and not processing interrupts.
Arguments:
Arg1: 0000000000000019, Clock interrupt time out interval in nominal clock ticks.
Arg2: 0000000000000000, 0.
Arg3: fffff88002f65180, The PRCB address of the hung processor.

I've also been running some stress testing but haven't had a crash as a result of it.
Thanks.
