I'm a complete newbie at tech stuff so please be patient with me and tell me any additional information you need to help me.
I'm using Vista SP1 and I've recently noticed that the maximum frequency in the resource monitor flatlines at 54%. As I'm a bit of a gamer and have spent countless hours tweaking Vista in other respects, this is completely unacceptable to me. To make sure that it wasn't just resource monitor freaking out I installed several other applications including Everest and they tell me that my processor is clocked to about 998 MHZ for both cores. It should be 1828 MHZ, according to Everest. Any time I've tried using Notebook Hardware Control to switch my max processor state to more than 5% it simply says 'Error changing the processor state'.
*I'm using Vista SP1 with a Mobile Dualcore Intel Core2 Duo T5550, 1.83 GHZ.
*My chipset according to Everest is an Intel Crestline-GM GM965
*On booting, the BIOS menu gives me two options: A. Low Frequency, and B. dynamic processing. Choosing Low Frequency makes no difference. I have not found any other options in my BIOS relating to the processor.
*Again, according to Everest, my CPU power is 997.6 MHZ at an FSB of 166.3 MHZ and a multiplier of 6.
*When I go into vista power options, the option that says something like, 'when CPU starts to heat up, A. Turn down the CPU B. Turn up the fan' is no longer there. Also in vista power options, changing the max and min processor frequencies makes no difference, as my maximum frequency stays at 54%.
*My fan is running fine, but my temperature stays around 56 degrees Celsius so it seems like it runs pretty quiet generally.
*I have done a complete reinstall using Vista lite, disabling many different programs, disabled many services including system restore, and generally tweaking the computer to death. I've also repeatedly run CCleaner, Startup Inspector, and I've defragged the HDD, page file, and registry(I can not verify whether or not the reinstall was the exact point at which this problem occurred. I know that when I first got the computer it was loaded with all sorts of OEM crap, which prompted me to buy a new Vista CD, which I promptly used with Vista lite. I feel like I had this problem at least once before reinstalling though).
