If occasionally access to the system, or can enter the safe mode (F8), first reinstall the video card driver, and then to clean up the gold finger, generally can be resolved. If the system cannot go in, is very likely the memory damage, often occurs Huaping phenomenon in the chaotic character of the system is started, it must be replaced or memory card.The temperature is too high, the graphics card fan is not good, or the case of wind is not good, resulting in high temperature, high summer temperatures, this situation is seen; to touch the memory chip temperature, check the graphics card fan is stopped.
