It's the stock for whatever the computer he has (some where in the specs)

Are you sure this isnt speedstepping? (its downclocked before and then it raises to the full clock when needed) which would make a lot more sense. If its true overclocking, disable it in the BIOS.

How do you disable over clocking in the BIOS? He doesn't ever overclock, right when he installed Windows 7 it would auto overclock.

what is it overclocking to, and what is the original clock? I still dont think this is overclocking by default.

I think this is the computer. And these are the specs.

If the above is correct then I don't see how the OS can OC the CPU.

Doesn't the motherboard have to allow an OS to overclock the CPU?

Also it states here something about lock-ups and restarts when playing large 3D games. It says that the computer is installed with 3GB so I doubt thats the problem. If he's using the onboard GPU then I reckon a new PCIE GPU and a PSU will overcome this.

I'm fairly sure it's speedstepping and your friend is just very confused about it. The difference is that instead of overclocking when you need it, speedstepping underclocks when you don't need the cpu at full clock.

MW2 is a very intense game and it, with the 4800 graphics card and the cpu at full clock overdraws the power supply, causing a reboot.

That's my best guess, but I cannot confirm until I know what graphics card and PSU it has.

He doesn't want to risk going in the BIOS and messing things up.

There's not a whole lot you can mess up on an OEM computer...
