I bought this pc just over three months ago.  All of the sudden it showed a blue screen and then an error "Boot Device not found. Hard Disk - (3FO).  I went to YouTube to find solution but none helped.  Unfortunately this was a 3 month warranty item.  I constantly buy computers for my business. This time i wanted to try a mini pc.  Unfortunately the product this company sells is bad.  I will not use this company again.  Big mistake.
