This computer was great in the beginning. The Operating System.,webpages,and programs loads fast. I am starting to get no disk errors. Today I had left the computer for 5 mins. The blue screen of death appeared.  I was pleased with the performance of the computer. Now I am contemplating returning it. This computer is not booting up right away . I have to turn it off then turn it on again. Before it will start up.This is a update. It lasted a year. Programs are starting to freeze. I have to push ESC 5 or 6 times before the program unfreeze. When my computer work. It works well. Every now and then on startup my computer won't go to the log on screen. And I have to shut it down. And restart it to get the log on screen. This computer has a bad disk. I am getting a no disk found error. It lasted a year.
