Clock speed keeps lowering!

[NeedHelpASAP]

Hi, I've had an IBM thinkpad G41 Pentium IV 3.33 GHZ with 1.25 GB RAM for over a year now.
Usually it ran without a hitch. The VGA card blew out a year ago and I had it replaced. Ever since then, start-up has been so slow, but that's not why I'm here.
My question is this: Often the clock speed lowers from 3.32GHZ to 433MHZ.
Of course, this renders the computer very slow. When I open up the "Power Options", the power setting reads "Maximum System Performance" which it should, but the Clock Speed still reads 433 MHZ. Now once I restart the computer, the Clock Speed comes back to 3.32 GHZ. But then after a while, it drops back down to 433MHZ for no reason that I can tell.
Anyone have advice on how I can keep the clock speed stuck at 3.33GHZ?
Thanks guy

Don't know why that happens, must be a power saving feature. My Athlon does that as well, sometimes it's 800Mhz, and sometimes it's 2.21 Ghz.

I could say that your BIOS is messed, and the FSB setting isn't correct... But it's an IBM.

So it IS a power saving feature. It's called SpeedStep.

Talldude, yours is something like that too, it's called Cool'n'Quiet.
