  1. Open up the PC cabinet by unscrewing the screws. Make sure you are grounded.
  2. Find the RAM sticks connected to the motherboard. The sticks are generally placed beside the processor.
  3. To remove the RAM, find out the small clips at the ends of the RAM slot. Gently push the clip downwards to unclip the stick.
  4. If you are using a single stick, change the slot and for multiple sticks try to exchange the slots between them.
  5. You should be careful while reinserting the sticks. There should be a small notch on the RAM module which shall be matched to the slot, if you push it in the opposite direction, the pressure can damage the module. Match the gap and push the module gently into the slot until you hear a clicking sound.

Some of you may be wondering how to reset the BIOS if we don’t have a monitor to look at the setup screen. Well, the embedded BIOS firmware is powered by the CMOS battery. Removing the battery can reset the BIOS. 

To reset the BIOS:

  1. Open up your PC case.
  2. Find the CR2032 CMOS battery on the motherboard. It is quite distinct looking from other components, generally a coin-size flat component. It is more likely to be found near the PCIe slots.
  3. In case of a small-sized motherboard, the CMOS battery can often be found inside an insulated plastic wrap, generally blue in colour. Please refer to your motherboard user manual if you are having trouble locating it.
  4. Next, we need to remove the battery. Find the lock on the battery slot for the people with coin cell batteries. Push the lock to the side and the battery will pop out comfortably. Please note the battery polarity. The top side is likely to be the positive side with the (+) sign.
  5. The CMOS is attached with a wire for small motherboards with the wrapped cell. Disconnect the cable connected to the motherboard. Again, note the polarity of the wires before removing them. You can also click a picture of the motherboard to check for any wrong changes later.
  6. After removing the battery, press and hold the power button of the PC while keeping it disconnected. This will release the charges held by the capacitors and discharge them.
  7. Now, we have to reinsert the battery. Keep in mind the polarity of the battery insert and push the coin cell into the slot. If you have the wired one, reinsert the cable header; also be sure to check the polarity.
  8. The BIOS should now be reset.
