4. Restart your computer.

Check if the monitor is working this time or not. Now, there are two possible conditions –

This way, continue this process until you have identified the culprit behind this issue.

2. Detach the power cable from the power source.

3. Now, open the cabinet.

4. Remove the cover from your machine. You can see the rectangular green RAM sticks attached to the motherboard pins.

There should be either 2 slots or 4 slots.

5. At first, toggle the clips at the side of the slots.

6. Then, detach all the RAM sticks carefully from all the slots.

7. Next, clean the dust of the RAM sticks and RAM slots on your motherboard.

8. Now, attach one working RAM stick to one of the motherboard slots and connect all the power cables, then restart the machine to check the motherboard slot is working or not.

This way, check the functionality of all the slots.

If any of the RAM sticks are not working,  you have to replace them. If the motherboard slots are not working, simply don’t use the particular slot.
