I have been having an issue with my Dell laptop. The CPU you will throttle down from 2400MHz to 750 MHZ, usually while playing games or while Firefox is running with many open tabs. I have the most recent bios (A34) and the issue persists. Reading about others having the same issue with this model (google "E6400 throttlegate" for some intersting information), I thought there would be a straight forward fix.




The ususal reccomendation is to update to the latest BIOS to remedy the issue but, as I've done that, I'm not sure what steps to take next. 3rd party apps are acceptable. Thank you in advance.

when it goes down, are you experiencing any performance issues when it does so? many laptops will throttle down the CPUs when theyre not using all the necessary power-it maybe possible the game simply using using it to the full potential.
