Need A New PC

I know that my pc is still working. The problem is, sometimes it is acting very weird like the different characters that appears when I type a certain key on the keyboard. Not only that, last night as I was shutting it down, it took forever to process. I waited and waited until around 20 minutes, it was still not shutting down, I already pushed the off button. I know that my pc is already antique. I got a new netbook but I still love this old one. I guess, I need a a new one again early next year. I need to ask first my financier...wink! Hope you had a great day today!
