hello
my laptop runs some good graphics games at medium-high settings, but it only happens for the first time i open the laptop and run a game
after i close the game, and restart it after sometime, i experience heavy performance slowdown(even if i adjust the graphics settings and play with the lowest possible settings)

i checked the fan and its performing normally, air is going in and out like it should, fan is clean...laptop is not getting overheat either.
i use tune up utilities and my HDD space and registry etc stuff are all okay, what could be the issue?

thanks.
