Game Freezing. Hardware Problem?

Question

I have a problem that someone may be able to help me with.
My Specs:
MSI P45 Platinum
Intel E7400 2.8Ghz
MSI R4650 1GB
2GB RAM
I have bought Call of Duty Modern Warfare 2 and every now and again it freezes and all that I can do is restart. This has also happened in other games and is rather frustrating when you have almost completed something.
I have a suspicion that it is a hardware problem because I have Dual Core Center and it tells me that my FSB is 134Mhz, my Vcore is at 1.24V and the numbers are purple. I'm guessing purple means that it is not normal and my FSB didn't used to be that low. I have tried changing both of them but it just crashes my PC and I have to restart. I have little knowledge of overclocking so I have little idea of what I'm doing  . If you could help that would be great. Thanks

Your mem V couldn't have been too high. Kingston's 1066 max rating on that mem is at 2,2V. Your memory's JEDEC standard's should include the DDR2-800 at 1,8V. This you have never confirmed, as we requested you previously to supply your CPU-Z SPD tab screenshot. Thus your memory can operate safely according to the manufacturer at 1,8~2,2V.
Safely does not necessarily mean stable.
Almost any (high quality) DDR2-800 chip with a heat spreader is able to operate at 2.1-2.2V
Now a less known thing: if you raise the voltage above 1.9V, they tend to run faster (and they become unstable at 800MHz).
Above 2.0V, you have two options:
1) to change the FSB/DRAM multiplier and to make them run faster (5-5-5-15 at 933-1066MHz)
2) to lower the timings (4-4-4-12 at 800MHz) and to make them with faster access.
Both operations are faulty, because you'll get 2 cents performance boost and 200 bucks troubles. 
Now coming back to DDR2-800 chips, the best match is a voltage of 1.85 (anything between 1.80 and 1.90).
p.s.
The above statements are also true for DDR3 and 1.5V
