CPU overclocking causes 3D games to crash frequently

Q: My computer uses the P4 Celeron 1. 7GHz CPU, the GeForce 2 MX400 graphics card (display core and video memory have carried out a small amount of overclocking), running Office and other software normal, why run "back to the German headquarters" and other games when the frequent crash?

Ttboy: Part of the video card in order to save costs, heat dissipation is poor, that is, not in the display of core and memory to install the cooling device. Run a large 3D game, the graphics card needs to work hard, the calorific value increases, plus you to the graphics card has a certain amplitude of overclocking, calorific value continues to increase, so when these calories can not be distributed in time, will lead to the graphics screen rupture or even panic. You can install the thermal device for the graphics card, this can not only avoid the above problem also can enhance the video card overclocking ability, TT's Pure copper video card radiator is a good choice.
