Hi there, I have a computer which are about 10 years old. And, the last time I use it are 4 years ago. And what I remember is, I accidentally disabled USB Mouse and Keyboards. I know how to fix it, just re enable it, but on this case, I even can't move the mouse and the keyboard. And that makes me can't access the BIOS setup. Any help ? Thank you. N.B : sorry if my grammar isn't good

If it's 10 years old does it have PS2 ports? You should be able to pick up a PS2 keyboard and mouse on the cheap at a shop or goodwill computer store.

Yes, they are round. mightywiz was requesting your remove the CMOS battery on the motherboard. Pull the power cord. Open the side of the case and ground yourself on some bare metal. Remove the CMOS battery and hold the power button down for 30 seconds to drain off any power. Replace the battery. This will revert your BIOS settings to default. If legacy USB is the default setting in your BIOS your USB keyboard and mouse should work. If not you will need to get yourself PS2 devices.

 

Most motherboards have a jumper you move to clear the CMOS settings. What is your computer's make and model number?

It would be a good idea to purchase a new CMOS battery.

The USB port still work, when I plug the mouse in, the mouse turned on the its light, but it doesn't give any input to the computer. And, how if I install a keyboard app for android and plug my android into the computer and acess the BIOS setup ? Will it work ?

You said, "Pull the power cord. Open the side of the case and ground yourself on some bare metal. Remove the CMOS battery and hold the power button down for 30 seconds to drain off any power. Replace the battery." I've pulled the power cord, and opened the side of the case. But, idk which one was the CMOS battery. I'll take a picture of my computer

Some said it's because of RAM, and what shall i do with the RAM ? N.B : After i fix the first problem, the monitor works, and i can use my keyboard to access the setup, and then, i didn't change anything. I exit the setup, and the windows logo appears. After a few seconds, the monitor get no signal.
