I received the computer today and tried to get it up and running. I turn on the monitor, the keyboard and the mouse unfortunately I can't get past the welcome screen because the keyboard doesn't do anything and neither does the mouse. I'll keep watching and looking for more video tutorials to see if I'm doing something wrong.  If I can't find anything to help me fix this, then I'm stuck with useless crap and a waste of money. Just be careful when buying this used garbage.Update: The good news is that since I complained to the seller, they sent me a new keyboard and mouse and that fixed the problem, it's working now. However, I will not change the rating due to this unfortunate incident and bad experience. I think they should check their products before sending them to customers.
