Along with the black screens, I'm also having problems with the USB ports. My wireless mouse (using a USB dongle) randomly will stop working. I have to either unplug/plug it back in, or completely restart my computer. One time, the mouse stopped working so I tried a wired mouse and it worked for 5 seconds then stopped...had to restart. This happens regularly. Any thoughts on what the issue is?
Got a tip for us?
