I got a cyberpower pre-built a week ago, it worked for a few days without issue. All of sudden it has stopped working. It turns on, lights up and fans spin, but monitor, keyboard, and mouse don't work at all, it's like there'a no signal at all coming from the pc, i've tried different usb ports and monitor inputs with no luck. Any ideas on what is causing this how to fix it?
