My pc |E2200 2,2GHZ 4 GB ddr2 ram, Nvidia 210| i think is capable of playing
cs 1.6 and Counter strike Nexon Zombies
at a decent fps lol. But my CPU usage is 100% idle i opened up cs 1,6 it played decent with lagg spikes and CSNZ went in 5 fps. But today i discovered my e2200 was runing 1# Core 95°C and 2# Core 92°C. There is no termal paste on the CPU and the fan is not correctly installed on the CPU (only 2 pins are attached to the mb) How do i run CSNZ on good FPS? Will it run good the game if i apply termal paste and install a new fan?
