This PC when purchased claimed to be compatible to to Windows 7, It never was. I was unable to read any of my saved files, and whenever I attempted to write and save a document, it would jumble all the words, rendering it unreadable. It kept sending me messages to purchase more software which was ridiculously expensive. I did my best to deal with this piece of garbage, until one day it crashed and the screen turned black! I was unable to reboot or use it again. I had a technician look at it, and he told be it was useless. This is the worse item I ever purchased from Amazon! I will never purchase any computers from Amazon again. I paid a lot of money for a piece of junk. I expect a full refund.  I have not been able to communicate with anyone concerning this problem. That is unacceptable! I have never experienced this difficulty with any computers purchased in the past? I expect better service. Please respond and explain
