Operating System: Microsoft Windows 10 (64-bit)
I was experimenting with a 2nd video card on my recently purchased Z420. The video card was acting flaky so I went into the BIOS, and changed only one setting that pertained to "Video". Of course I stupidly saved it.
Now, the computer beeps 6 times (hinting at the video issue), but never shows the screen. I went back to the original Video Card, with no different results.
I'm told I should be able to "flash" the bios, which I agree. However, with the screens unusable, then I need to create a bootable flash drive. I have a flash drive with nothing on it.
If I use "run" on the .exe, it never gives me the option to create a bootable USB Drive.
So I am either doing something wrong, on the bios download, or stupidly I am going about this the wrong way altogether (maybe I should not flash the bios). I read some posts about clearing the CMOS but am hesitant to do so, because it either works, or completely screws up the motherboard.
Any other ideas?

by chance was that "one" option the compute one? in other words did you enable the compute option for that pci-e slot?
if you did and did not do it to any other slots you can recover by inserting a video card in any other slot
if you changed it in all pci-e slots, then you are up the creek so to speak, until/unless someone writes up how to blindly press the nessary keys on the keyboard to reset the compute option
doing a bios reset/cmos reset will not help as this setting persists and can only be changed back by manually changing the bios option
you have also learned a major lesson, don't play/change settings or jumpers you do not fully understand,......take the time to read up and learn what they do first
i have comented on what the compute option in the z series workstation does several times, use this forums search function to locate the posts
if not a compute option setting, then a cmos reset may resolve your problems. i strongly advise not to try a bios flash while you do not have a visable display since a bad or incomplete bios update will leave you with another issue namely a corupted bios besides the display issue
