Question Reset BIOS without CMOS battery

[tomilache]

So im in a really specific situation here, i basically just turned UEFI boot on, and it has no display. I wouldve just removed the battery, or short circuit the RESET pins, but sadly, both of those are under my gpu, which covers 1/3 of the motherboard, and that i cant remove because its being blocked by a part of my case. I dont even know how the guys got it in there.

TL DR: Need to reset bios without short circuitting the pins or removing the CMOS battery.

which motherboard is it?

Which case?

if the motherboard has no reset button, you will have to use the CMOS jumper or battery removed

remove the drives or cables of your system, power on, eventually the BIOS can be reached to alter the settings again

try booting with a bootable USB flash drive

I have a
0GY6Y8. The cmos jumper i think is also under the GPU. If you meant unplugging the power, i did. I unplugged it and left the pc for 12 hours, still nothing. The case is from a optiplex 7010 tower i7 3770.

how long is your GPU?

Saw it, but why should the GPU then be covered by anything?

Everthing within including the borders is the gpu placement roughly.

The gpu is behind the metal part of the case, here's somehow a picture.https://media.discordapp.net/attachments/1133471464398540820/1159116245111672892/Picsart_23-10-04_16-13-25-222.jpg?ex=651eb6a0&is=651d6520&hm=5a9296522cc539a3e44cf4f7f548ab833501ec603cd66868e7dcf788fd886aa9&

remove the plastic part, then the GPU, lift the lever on the motherboard to the right which is holding the GPU before pulling

Interrupt start by turning off power several times and BIOS should go to Safe Mode with factory defaults, same as after clearing CMOS.

turning off power as in disconnecting the power cable or pressing the power button on the pc?

There is most probably power switch on the PSU

I did this about 7-10 times, and still nothing. Am i supposed to do something else?

Try holding Start button while switching power on, that also works on some systems.
