BSOD Windows 7 Ultimate x64

[Oldzz]

Hey all, recently a friend of mine installed an OEM copy of Windows 7 x64 on my MSI GX740 laptop. This is not the original install, as 64bit home premium came factory installed.

My system is only about a year old and the specs are as follows:

Intel i7-720QM 1.6ghz
ATI Radeon 5870 1GB DDR5
4gb DDR3 Ram
500GB HDD

Since the recent install, I've been experiencing regular bluescreens with the error code:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033

Additional information about the problem:
BCCode: 1a
BCP1: 0000000000041287
BCP2: 0000000000000018
BCP3: 0000000000000000
BCP4: 0000000000000000
OS Version: 6_1_7600
Service Pack: 0_0
Product: 256_1

Any help would be GREATLY appreciated, attached are the relevant dump and performance files.

Thank you!
