I received the desktop computer about a week ago and after opening it booted up fine but I discovered it was supplied with a very poor wifi adapter interms of a speed. I left computer running for couple of days but didn't use it actively and today when I checked I found out the display is gone, I tried to reboot and re-plug and everything but the display doesn't showup.I need to return it and get a refund immediately.Update 1: They sent a replacement computer, it worked for 1 hours and stopped with a blue screen. Now it doesn't show any display on monitor even after powering off and on again. Same behavior like the previous desktop they had sent.
