CPU keeps dropping in frequency

[Switch84]

I have a AMD Althon 64 3500+ which normally runs at 2.19ghz. However, if i play Counterstrike source the frequency will drop to 984Mhz. I have never noticed this before until yesturday. I have Formatted the HDD and Reinstalled windows and received no joy.

Any ideas what might be causing this? Its Kinda puzzling me.

Many Thanks

Chris

I forgot to add, its a compaq/hp computer, so the bios is their own 'software'. There arent many controls in the bios that I can play with. and I havent seen an option called Cool and Quiet.

Just had a look at the bios and there isnt much to choose from in terms of options.

System 35 c/ 95 f

Just had a few rounds on CS:S and owned, checked the cpu frequency and it was running at 2.2ghz.

Many Thanks for the input guys.
