I have an HP lap top with Windows XP professional and for some crazy reason, periodically when I check the system icon it says the processor is .8 ghz instead of the 1.8 ghz which it truly is. Sometimes it is 1.56 or some such. I haven't really noticed if that's related to any system problems but some times certain programs (games) process much slower then usual. This is strange and a relatively new occurance. I'm wondering what might be causing it, how it's detrimental, and how to correct it. Thanks a lot.
