Lately I have performed a format and clean installation of my laptop. I have reinstalled all of my required drivers. For some reason while I am playing, about 5minutes of normal performance the game starts to increase in lag until it comes to almost a complete stop! When switch to my task manager the CPU has gone up to 100%. I have played these games without no problem at all before the format. Could it be a hardware problem or is a software? Anyone has experienced or solved this problem before.
CPU - Intel core i7 (2.8Ghz)

Thank you in advance
