BSOD Caused by Driver ntoskrnl.exe

Having seen other help from this forum I thought I'd post my problem and see if you guys could help me out.

I just built my girlfriend's PC a few days ago, all was well but now a BSOD appears randomly, so after using BlueScreenView on the dump files it all originates from one driver.

The PC in questions specs are almost identical to my own (minus the 1TB HDD and her MOBO is the Rev 3.1 version of the same MOBO).

I've attached a copy of the dump files to this post if that helps anyone.
I've already tried chkdsk which gave no errors.

Thanks in advance

Sorry to hear about the BSODs. Please follow the instructions below:

This happened again today, out of the 5 time in the past few days 3 of the errors were MEMORY_MANAGEMENT. I've attached the latest minidump in accordance with BSOD forum rules
