my new desktop The old one has accompanied for almost 7 years, which I brought in ZhongGuanCun electronic market when I just started my postgraduate study. Recently there always came out some wield sounds when I switched on my desktop, and one of my college roommate also gave me advice that I should change for a new one. He told me that I could spend less money to get the performance improved to a large extent. So at the time of price war on e-business, I selected some componnets of the desktop to DIY a new desktop on my own. Frankly speaking, I almost forgot how to build the whole computer cause the last self-assembled desktop was made about 10 years ago. At that time, the personal PC was still not so popular as today. 80% of my classmates bought the computer and assembled on his own. The conjuction of the components and connection of the cable is almost the same as before, but the interfaces become more and more various, there is even no interface for my old CD-ROM. And the installment of the operation system can be done by a USB instead of the compact disc. Right now, all the building blocks are ready except the hard disk, because when I was about to buy new HD, the price had increased, I felt very uncomfortable. This is the normal phychological phenomena. So excited to get my new desktop ready but still do not know when can be ready. A little frustrated, still need to download the win7 OS from the Internet. Hopefully all this could be done by the end of this week.
