If you don't have an onboard display to plug into, open your PC, pull the CMOS battery for 30s, and plug it back in. This will reset all your settings to factory defaults.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Many fancy motherboards have a button to reset these settings as well. Often the bios settings are referred to as CMOS settings as well.
Yeah, but it's almost pointless to give an "if, then, elsif, elsif" scenario if just removing the battery does the same thing, and all motherboards have a battery for the CMOS.
the batteries are being soldered onto the motherboard now-a-days
Never seen that, and I build with hundreds of variants from all the big manufacturers. Haven't seen that once in a PC, Laptop, or SFF.
i last saw it the last time i was a system admin tasked w spec-ing out hardware for our offices in austin, ft. lauderdale, denver, and inland empire and i remember being surprised at how much worse they were than the thinkpads i had grown accustomed to supporting as front line tech in mountain view 10 years before that.
and now w that in mind: it would have been circa 2015 so the landscape should have changed by now; maybe they reversed course like they did the rubycon capacitors that caused the capacitor plague 15ish years ago.
You buy such a thing with Club Z points?
i though that was just a canadian thing
Do this one op, nice and simple. It's a smooth, shiny circle about the size of a US quarter somewhere on the surface of your motherboard and should pop right off
Try plugging your monitor in a motherboard port instead of the GPU ports.
Note this only works if your CPU has on-board graphics like most Intel chips (non KF variant) or AMD's G series processors.
Or the Mobo has on-board graphics... is that still a thing?
No, integrated grapics now means in the CPU
try the pulling CMOS battery thing (you also need to disconnect power btw), if it doesn't work there should be a CMOS RESET jumper on your motherboard, try shorting that.
Thanks, that helped. I also used the chance to finally clean up the inside of my pc a bit
If you disabled the GPU in the UEFI you'll have to re-enable it in the UEFI.
Pretty sure bro's monitor is plugged into his gpu, cpu/mobo may or may not do video
Don’t you have to start up the pc in bios mode like holding f2 f8 or f10 and change it from there? I’d reinstall the bios from the manufacturers website to default
