This refurbished PC/Monitor were received on 10/28/2020.  They had a 90 day warranty.  The desktop was slow from the beginning , but now it just keeps turning off for no reason and takes forever to turn back on and then turns off again.  The monitor also shuts down except for a message that goes across the screen non-stop.  I have reached out several times to the company via email and phone for help but to no avail.  Certainly one would hope for more than 5 months on an HP desktop and a Dell monitor.  Disgusted!!!
