You sold me a computer with a bad operating system on it. For the first few weeks that I had this PC I kept getting a blue screen with a message saying the PC had run into a problem and needed to do an update. It stopped doing that until last week when it did it again. The real problem happened yesterday when the blue screen message came up again. This time whatever that update was, it screwed up my PC. A message came up saying the update could not be completed because there were missing files on my PC. There is now something constantly trying to run in the background and the regular programming is interfered with. The PC is unusable in this condition. I tried to restore the PC operating system and was unable to do so because there are missing files. Upon further investigation, I discovered that what was put on this PC was Windows 7 which was then upgraded to Windows 10. So whoever loaded the operating system on this PC did a very poor job and I was sold a computer with a bad operating system. Now I'm stuck with a useless computer that I paid a little over $300 for because there is no way I can fix this. I am a disabled man who can barely walk. My computer is about the only thing I have to keep myself occupied and now I don't even have that. I had to borrow my neighbor's laptop to send you this message. I barely had this computer for 5 months and now it is dead and useless. I would have to call this a very, very bad experience.
