UPDATE 4-7-2017: About 2 weeks ago I called customer service, left a woman my phone Number she said someone would call me back I have not talked to any one yet!. After this unit froze up on me 2 or 3 times and the videos card must have been bad because the screen would jump down when trying to use it. So I just now thru it out the door with the rest of the trash. This one I bought from Blair and the other one I bought for a friend was not from Blair. So now i have to buy another AND IT WANT BE FROM BLAIR.Just now installed it, works good faster than my old one, It was cheaper to buy this computer with windows 10 on it than to update to my older computer to windows 10.  I just want to buy more memory sticks to max out the memory It has 2 more slots just can found the right type, don't want to buy wrong kind any help on this? I will update review later.
