power overheating HP desktop Pavilion P6361FR

[xantippe]

Hi!,

I installed for a HP Pavilion P6361FR Desktop dual boot Windows 7/LinuxMint13LTS for my family in Paris. (I Live in Holland)
Everything works fine exept the difference in powerconsumption.
The machine works silently under windows but under LinuxMint the power supply has to work constantly very hard. The system is not yet overheated but I think something has to be changed in the system.

Does someone know the reason of this problem. I heard something about missing the right graphics driver under Linux.

I can do some tests at the second half of february when Iḿ back in Paris for a week.

Thanks, xantippe
