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.
