BSOD when playing (any) games. [BCC code 117]

Hey,

So I recently got a new computer and every now and then when I run games the computer basically freezes. (The display shuts off, the sound loops, and I have to shut it off) I have a Lenovo Thinkcentre 7522J4U, here are the specs:

OS: Windows 7 Ultimate x86
CPU: Pentium Dual Core E5300 @ 2.60 GHz
Memory: 2 GB
Video Card:Intel G41 Express Chipset @ 782 MB Shared RAM

And here are the error details:

Problem Signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033
Additional info:
BCP1: 84F96510
BCP2: 8E041980
BCP3: 00000000
BCP4: 00000000
OS Version: 6_1_7600
Service Pack: 0_0

Any help will be appreciated.
So far it has done this in the following games: Modern Warfare 3, Doom 3, Call of Duty 4,

Thanks again.
