How To Clear CMOS (Reset BIOS) - The Easy Way

It's EASY and I will show you how to reset the BIOS and clear CMOS in ONE minute if you can no longer get into the BIOS (no POST, Black Screen, no display).

One note on turning off the system. If you are going for the battery removal, you want it to be completely off (and ideally disconnected, at this point you can also hold down the power button to get rid of any residual charge). If you are going for any other method, I never had a problem having the PSU connected to power, however, if you are going for any of the screwdriver shenanigans, make absolutely sure, you only touch those pins. You can actually kill the motherboard and possibly other components if you if you connect solder points.

If in doubt, find the manual

Some motherboards have a CLEAR CMOS button.
Some motherboards have two pins, others three.

From the bottom of my heart thank you. I was losing it trying to get my bios working again. All I had to do was find a button on the motherboard. Everything I tried previously was software related. I'm trying to install Mint on my computer and went into BIOS and turned off secure boot and fast boot then turned on legacy and suddenly the computer always turned up a black screen and no bios or menu options.

I suspect it was because it was only trying to load the mint program from my usb as I disabled loading windows but the bios override had windows listed as #1 so it should have loaded anyway if it couldn't load my usb. I've been trying to get it to recognize mint on the uefi and foolishly put it in a state where it couldn't load anything.

Do you know why it won't load my mint usb -uefi and always runs windows instead? I really want to try this operating system.

Look heres what I did after overclock made monitor go black and keyboard mouse stopped working
Bios reset by clear CMOS but pc wont start. I did this clear cmos by JBAT1 with screwdriver by placing screwdriver and linking 2 nodes.
Again pulled out battery according to YT.
Then moved my 2 rams on next tries, 4 slots so changed 1rst ram position then changed 2nd ram position then tried single ram.
Then at last changed first ram and out 2nd ram in original position at start and put screwdriver in JBAT1 but didnt connect 2 nodes.
I dont know if last step fixed it, my gpu losened and gave white motherboard light but it auto resolved.
Msi auto ram overclock did all this, overclocking wasnt this pain prev generations...

Any idea where to find cmos clearing pins or battery in a Toshiba satellite L55-B5276 (with DAOBL IM6FO motherboard)? I've been looking for a week and I've seen every video on the subject at least twice???

Bro I need help. Normally my monitor shows the display, but when I try to access BIOS settings or try to use Advanced Options to reset my PC or Repair, it shows "No Display Port." Also the same issue with the HDMI. Then, when I press the restart button, my PC restarts normally, and the display works again. I can't access my BIOS settings or use Advanced Options. What should I do? My BIOS is in UEFI mode. My display cable is connected to the GPU Display Port. One day, I used our Walton TV with my monitor's HDMI 2.1 cable, and the TV showed the BIOS display. However, it’s not working with my monitor. I can't find a solution on YouTube as well.

Bro i have b450m gaming gigabyte i have 4 pins how i do clr cmos

[Fxyebulous]

My computer stuck in BIOS after adding/installed RAM stick, and I am starting to lose hope.

[DocPrille]

I have a GIGABYTE A520M H and i cant find the switch or anything i tried taking out the battery for some time but that didnt work either i see a clr_cmos but i cant get it together with pins pls help theres nothing in the manual

[taburetca]

please make a video on the allowable voltages during overclocking, this is the most important information during overclocking, there is no such information anywhere on the Internet (at once in one place). degradation occurs due to temperatures, not voltages, so if a large number of people have a processor that does not burn out at some voltage, then this voltage is safe, you know my voltages.

[jikika]

i tried everything, I also started the computer without RAM and then restarted it, only that it still doesn't start, I'm trying any combination of RAM in my slots but it doesn't work, I have a b450m ds3h

[ckgaming]

I have the pins what do I do with the screwdriver

[CoffinCrawler]

Thank you, thank you! I did the CMOS button push, but it still didn't work... replaced the battery and it's running now, booted fine.

Thank you again... saved $ going to a shop.

Also... Gigabyte kinda blows.

[Awcv]

It does not work? :( Why? I did everything.

[HG-tiug]

Why can’t you show instead of blindly saying
