Hi
Recently i've upgraded my OS to windows 8 Pro.
Since then, when i open an app or a new internet tab that requires some effort either from shockwave plugin or gpu processes, i notice a cpu spike that lasts for 3-9 seconds.
Those spikes increase the cpu temperature of 50ºC to 70ºC.
But when the spike is over, temperature gets back to it's usual (50ºC).
I've tried almost everything i read, but so far, nothing has solved the problem. I tried the clean boot, safe mode (network option checked), enabled manual windows updates, scheduled maintenance to a specific hour, disabled an option that allows atheros controller to turn off the device when the laptop is idle.
My drivers are all up to date, so i dont really know what's happening, thus i would sincerely appreciate your help.
Aditional Info:
Toshiba Satellite L755 - PSK2YE (cpu - i5 - 2.30 GHz / RAM - 4 GB / 64 bits)
PS: Three months ago i sent my laptop for a toshiba center to clean up the vent.
I use Balanced energy mode, but the same problem happens when i use the high performance one.
However in power saver mode there are no spikes at all. I used to see the same behavior when i reduced the maximum processor state to 95%.
