My computer had a problem for almost half month, the problem was that the computer will automatically shut down by itself. At the beginning, it seldom shut down like several times per week. But from last Saturday, the computer would shut down only after I boot the computer, I can’t use it.
I suspected that my computer’s mother board had problem. Later on, I learnt from Internet that the power supply case will cause such problem if it is not good enough.
I checked newegg.com.cn and decided to buy a Hangjia LW-8388s, which is designed for small servers, power case. I called Huang Zhong Ping at Wednesday and he delivered me a new power case at Thursday. Huang charged me RMB 400 instead of RMB 288 list price at newegg.com.cn.
The new power supply works well, and the noisy is much lower than before.
