Out of nowhere my wireless mouse froze on my second monitor. About 10 seconds later, both monitors shut off. The cpu shows the power light is on and the fan is blowing. I tried rebooting and detaching the monitors and plugging back in. Same thing. Batteries should on mouse should be fine. It gives a blinking notification if running out. None of that fixed anything. When i hit the power button on the front of the cpu nothing happens. Any advice?
