Asus B250 Issue - changed a BIOS setting now won't show BIOS screen

[hashyhashy]

Hey all

I'm building a new rig and had the BIOS on the monitor, changed one setting, saved and restarted and now all I get is "No Signal" displayed on the monitor.  Everything appears to power on, CPU fan spins, ethernet port lights are on etc, but I just get no signal to the monitor.

I've tested different USB ports, different HDMI ports, etc. but I can't get the BIOS screen to show to reverse the setting.  The setting I changed was "enable CSM" - was looking for the option to boot from USB (to run SMOS).

Running latest firmware (1001), intel processor, ddr4 ram etc.

Anyone know what to do?  It's driving me nuts lol.

Cheers in advance

Did you tried clearing cmos and see if issue is gone?

No I didn't know about it til you said, I will try it if you think it will help.  Will that reset everything, back to default settings?  Unfortunately I am away from my rig right now and can't test it but thanks for the suggestion

Clearing  CMOS will send you back to default factory BIOS settings.
