Random but similiar game hangs

[TheMarshmallowBear]

I've upgraded to a new PC like two weeks ago, and noticed that despite everything running fine on max details on Direct X 11 (yay for WIndows 7). The game tends to freeze, forcing me to reset my PC manually.

I have
Windows & Home Premium 64-bit
Six-Core Processor (3.3 GHz, but can be overclocked to 3.6)
8 GB of Ram
Direct X 11
and AMD Radeon HD 6700 Series

Everything is set on high and gotta admit that there's a small graphical glitch where Pillaged objects as well as certain terrain items do not eem to bother rendering (they remain invisible). IN fact, Pillaged objects have no smoke coming from them.

Note - It appears the freezing is computer related.. unless Civ 5 and Sims 3 are secretly working together.
