And if so, why are there 2 of them?

Those do not appear to be the right jumpers. Can you add a full picture of your motherboard?– DrZooCommented Oct 15, 2018 at 17:48

What computer model is this? It's hard to zoom a bit an see anything. It becomes too pixelated.– DrZooCommented Oct 15, 2018 at 18:32

As it turns out, the pins you have circled in the first picture does contain the correct jumper to reset the CMOS.
By looking at the service manual for the Inspirion One 2305, the reason there are two jumpers is because one jumper is CLR_PSWD (clear password) jumper, and the other is the CLR_CMOS (CMOS Jumper).
To reset the CMOS, you'll want to turn off your PC and unplug the power cord. Move the jumper on board component 18, which is the jumper furthest to the right in your original picture with the red circle. Move the jumper from pins 3 and 2, to 1 and 2 for 5-10 seconds. Then put the jumper back on pins 3 and 2. You can then plug in your PC and turn it back on.
Here is the motherboard manual that shows the system board components.
Here is the pinout from the manual.

There's four? The manual says and shows only three. I added another picture from the manual.– DrZooCommented Oct 16, 2018 at 0:19

This is strange indeed, I guess I shall try both 3-4 and 2-3 But notice the manual is 2310 instead of 2305. I will search it up. Commented Oct 16, 2018 at 0:28

Yes it appears the one above is 2305, and the one below is a different one, but both display only three. Commented Oct 16, 2018 at 0:32

Yeah the only difference between 2305 and 2310 is the location of the jumper.– DrZooCommented Oct 16, 2018 at 0:39
