I am glad to tell you guys I fixed my computer on my own! As everyone knows I am a computer idiot. I only use my computer to work, study, watch movie and so on. When my computer was in trouble, I have no idea to fix it and I always go to the maintenance center. It costed my money and time. So I did some research. Compared with a lot of software, the SmartPCFixer is the best. It is the easiest and safest one!
