I found 2 issues with my new zenith extreme:
1. When I use Displayport in my graphic card, I can start my pc 1 first time only, after I shutdown and power up again my screen is always black. I have to unplug power cord, replug it then I can start my pc again (but only the first time after pluging power cord).
2. In Bios setting, when I change "ErP ready" to enable (to turn off power of USB ports after shutting down), the fan's led light will be always off even when cpu is on.
