just unpacked a clean computer. (computer was well packed). called seller Tech Mart LLC for help. they were busy and did not call back. luckily i figured out what to do.wireless mouse, wifi, external hard drive, and printer installed automatically. downloaded open office to get a good free writing program. wifi was extremely slow so i added a tp-link dongle (1300ac) which helped a lot. computer is still a little slow but that's compared to my chromebook which has much less overhead.will write back later if and when problems crop up.
