I bought the computer as a station dedicated to remote work.  After a few day’s of being setup and being untouched, and previously working, it would not boot up.  All I heard was a series of 4 beeps; I communicated with the seller, who provided instructions for me to test the ram out individually.  That did not work, so I returned the item.  Now the seller is claiming I caused the damage (after following his instructions) and that the machine is destroyed and unusable.  In my opinion, this seller is unethical and I will not ever purchase any items from this store.
