it stay's normal for a while on 75-79 degrees but the game lags and the clock drops at the same temperature after a while
after closing the game clock goes to 1800 MHz and stays there and temperature goes to 60-70

Definitely sounds like a cooling issue the maximum temperature for the chip is 63C see
so when it reaches the mid 70s in throttles it down to stop it dying. You need to either try reseating the CPU cooler or upgrade it.

Sorry I got them mixed up I cann't find the max temp for the TK-55 but I think the problem is the same. Being a laptop I suggest you try taking the keyboard out and blowing as much dust out of all the fans you can and check they are all spinning. You could try running it with the keyboard out as this improves the coolng.

i opened my laptop a lot and cleaned the fan and the whole laptop is dust free

To prove if its a heat issue or not you could run prime 95 and see if the CPU throttles down or not.

hi, i found something intresting today

i downloaded a MMORPG calles : ACE ONLINE but it works alright no clock going down and smooth gameplay so far
but when i go back to Battlefield the clock goes to 759 again i noticed when i get to 759 MHz the CPU stays that way for 1-10 min and then the GPU temp goes to 85-90 Celsius after the CPU pops back to normal the GPU gets back to 80 Celsius

please tell me what to do

It still sounds like a heat issue to me so try the prime 95 option and see what happens.
