[Zezima]

Yea so hi , remember my last topic about my freezing PC from "heat" so yeh now i found that its not from heat , cuz was doing some testing..Its becouse like my PC is weak , so when i play some game , sometimes my NOD32 antvirus will update and it will couse huge lag to my and my PC starts to freeze , then that shit starts that it freezes every 4 secs , and freeze goes up to 0.9 sec...Now i know that the problem is when my PC will lag from the lagy place in samp or somewhere it will start that shit...Eny suggestion what can i might do to get rid of it ?Like try opening my CPU and do something ? Unplug something and watch why this is happening ? Someone Plez
