Z170 extreme 6 - Help

Roybr wrote: Hello, guys I need some help, after trying to disable vt-d on the bios and selecting the option save and exit on the bios, my computer rebooted with a black screen. It doesn't show anything, and everything else seems to be working fine. My mobo is a asrock z170 extreme 6. I've tried to clear the cmos but with no results. Any suggestions for the solution? Thanks in advance!

That makes no sense, I've disabled VT-d on my similar board, and it made no difference like you described.

The Primary Graphics Adapter option is just above the VT-d option, any chance you changed it?

What are you using for graphics?

How are you clearing the CMOS/BIOS?

What CPU are you using?

What BIOS version are you using?

So you mean you removed the board's battery, and moved the CMOS jumper into the Clear position?

If that is right, is the battery in the holder with the + side up? You must see the CR2302 on the battery.

Did you forget to move the CMOS jumper back to the normal position?

If you did this all correctly, you might want to try starting the PC from the backup BIOS.

That procedure is described on page 23 of your board's manual:



Be sure to read the instruction carefully and completely. If you can boot the PC with the backup BIOS, your main BIOS seems to be corrupted. You'll need to do the Secure Backup UEFI procedure if that is what happened. Check the BIOS LEDs with the PC connected to power and running to be sure what BIOS you are using.

I would also check if you moved the BIOS Selection jumper instead of the CMOS jumper. The BIOS Selection jumper is just below the two CMOS chips. The Clear CMOS jumper is below that jumper, at the very bottom of the board.
