I had a lightning strike that took out most of my computers. It came through the ISP broadband coax and took out the ethernet ports and switches. My router is a old Dell running pfsense which I easily replaced the 4 port nic and was up and running with new switches. I was able to swap boards or put NIC's in all except one which is dead and cpu seems dead. And it may have affected other parts of the hardware, I dont know. Anyway:
I have a Asus Z170-K board that I picked up cheap, and it could be the problem, but I will explain.
The Z170-K now has my i7-6700K in it and seems too work except for a very annoying problem, it will not display BIOS or on boot up any output except VGA/RGB, Will not display on HDMI or DVI, however they will display if I boot up on the VGA/RGB output then switch the monitor over manually to HDMI or DVI.
Even when I set the monitor to default settings it will give me an error that says OUT OF RANGE plugged into the HDMI or DVI port on boot up. OUT OF RANGE means it cannot detect the type of signal or the signal is not compatible.
I have tried it on two different monitors and two TV's, same results.
I reloaded latest chipset and drivers.
Could the CPU have been compromised?
Is there a bios setting that I can check?
Thanks all!
