GPU usage fluctuations

I am getting huge drops in gpu usage in Crysis every 1-2 minutes, then it recovers in about 1 minute and continues this cycle.

Afterburner shows that my vram is not being maxed out (only ~750mb/1gb gtx 460).
It also shows that the gpu usage drops from 99% to ~30%.

Could my cpu be bottlenecking it? I can't find an OSD for cpu usage that I can use in games. I wouldn't think a PII x4 at 3.4ghz would bottleneck a gtx 460, unless the motherboard is cutting the voltage/frequency.

It is just odd how it started doing this today...

Yesterday I was playing at Very High on everything with about 30fps, playable, and had none of these drops.

I'm going to install warhead, after all, it's better optimized.

1. It happens randomly, tons of action or just walking around looking for ammo with 0 NPCs onscreen.
2. I'm not running at max settings. I'm running all "High" except physics@Medium and shadow quality@medium.

I don't think you understand. At every setting, all the way down to minimum, this gpu usage drop occurs. It doesn't matter, I will be at 100+fps on minimum, then it will drop to 4fps, with usage at <10%

Update:
This happens in every single game I own, crysis, warhead, men of war, l4d, insurgency.

Everything, no matter what the quality settings are at. What the f***, this is pissing me off beyond belief.

Yes I used driver sweeper and a reg cleaner before installing this and most recent drivers.

I found out what's causing it, but I can't stop it...
My cpu is underclocking itself to 800Mhz randomly. Cool 'n quiet is disabled in bios.

Idk wtf to do to stop this, it is way past ridiculous at this point.

I enabled, yes ENABLED cool n quiet and no longer have frequency fluctuations in any of my games.

I don't know how backward this situation can get.

To hell with it, at least I can play now.
