being upset There is a problem with my netbook. It always takes long time to shut down. My friend said it needs to be tuned up. I did it by installing tune-up utilities from internet. After tuning up, the new problems come to my netbook. The mobile partner is gone directly.. It was detected as a broken file. I uninstalled it, then I reinstalled. It's useless, also detected as virus in my modem. I can't use my modem right now. I think I need to repair it very soon. I am really upset *(╥﹏╥).
