My laptop is a TOSHIBA (dynabook) : satellite A660
motherboard: Toshiba NWQAA
CPU: intel core i7 740qm 2000MHZ clarksfield
GP: nvidia Geforce gts 350m (3D)
it came from japan .
it's running with an original japanese windows 7 home premium and a french language interface
the problem that it's cpu overheats quickly, about 65 degree at startup and when i run some requiring graphism apps or videos it's temperature rises at 100 degree and it shuts down itself. i opened it and i cleaned it's cooling fun system and the heatsink but the problem is still persists knowing that the battery's autonomy is weak(25min) i changed it with a new original battery but i have the same problem ....please help me what i have to do
