Hello. I use a IBM thinkpad laptop with windows XP, and for about 3 months, I've noticed something strange going on with my computer.

The link below shows the "normal" status of the computer.

However, the 2nd "2.00 ghz" suddenly drops to 798 mhz (sometimes lower) at random intervals, usually 3-5 minutes after I turn on my laptop and happens continuously. It will go back up and then go back down.
I don't think heat is the issue, because around 3 minutes after start up, these spikes occur but the computer doesn't appear to be overheating.

When i watch videos or play games, I notice intense lag and the video either freezes and the game lags very bad.

If anyone could help me with this problem, I would greatly appreciate it.

I think, it's Intel SpeedStep in action: http://en.wikipedia.org/wiki/SpeedStep

I see, so I read it a bit and it says that going to power options and then changing the scheme to home/desk will turn it off.
Should I do that?

It also says, "The SpeedStep settings for power schemes, either built-in or custom, cannot be modified from the control panel's GUI, but can be modified using the POWERCFG.EXE command-line utility"
Is there anything needed to change?

No, leave it alone.
It's useful feature, which prolongs your CPU life. It doesn't have to work hard all the time, if a hard work is not needed.

Hmm, interestingly enough, when I set the power scheme to Home/desk, there are no random spikes while watching a video or playing something. I suppose it fixed the problem...might be coincidence...but thank you.
