The most simple way to reset a BIOS password is to just clear it. To do this, turn off and unplug your computer, wait for a few minutes for the capacitors to drain, just to be safe. Then physically open your computer by removing the screws from the back, connecting the outer panel(s) to the main body of the computer, and remove the outer panels by sliding them back and lifting them away from the central part of the computer. Next, make sure to ground yourself, you can do this by touching the bare metal parts of the computer with two spread fingers every now and then, or by using an anti-static wristband (I would bet you don't have one, so just don't bother) this will prevent you from frying your computer. Now, locate the BIOS battery on the motherboard, it looks like a watch battery (that's because it is, but I digress)
The above is a picture of what your motherboard should look like, part #13 is what you're looking for, as we can see, it's near the middle of the board. simply remove this battery (there should be a small spring-like mechanism on one side of the battery that you press out to remove the battery). Also while we're in here, look for object #9 in the picture. There should be a jumper (a small piece of plastic covering two pins on the motherboard) here. If there is, then remove it. If there isn't, then don't worry. After about 5-10 minutes of waiting, replace the battery, making sure that the battery has the positive side up (the side with a big + etched in it). Replace the computer cover, plug it back in, and see if that all works.
I hope this helps!
