Now that you have prepped the PC, you can now start by opening the PC case.
Remove Side Panel
Check the side panel for screws. Depending on your PC case, the screws could be on the back or the sides.
Remove these screws and place them on a magnetic tray. Gaming or high-end PC cases will have thumb screws that hold the side panel. If so, you can simply remove them without a screwdriver.
Once all the screws are out, take the side panel out of the case. If you have a tempered glass PC case, handle them with care.
After that, lay the PC on the side.
Remove Memory Stick
Now that you have access to the motherboard, you need to remove the RAM stick. Locate the RAM in your motherboard. It is located near the CPU and should look something like the picture above.
The memory slot should have one or two locks on either side depending on the motherboard. Push this lock to unlock the RAM from the memory slot. Gently pull the memory modules out of the memory.
Check if there are any dark stains on the connectors on the RAM. If it’s dirty you need to clean it right away. Also, see for dust particles on its heatsink. If it’s dusty it might need some cleaning as well.
Clean RAM Stick
Once the modules are out, first clean the dust off using pressurized air. Use a small burst of air until you clean all the dust particles.
RAM stays upright in the PC case. So clean off any dust on the surface of the module.
Once you are done, clean them using rubbing alcohol. Make sure that the alcohol you are using is rated safe for cleaning electronic devices. Here are the steps to clean them.
Lightly soak the lint-free cloth with rubbing alcohol. Do not put the solvent directly into the connectors.
Rub both sides of the gold-plated connector of the memory stick.
You can also use an eraser to clean the connectors. Make sure that the eraser is clean and does not have any stains.
Once done, shake off any eraser shavings or particles. Rubber debris, being an insulator, may block the connectors. Make sure that none are sticking to the RAM.
You can again use alcohol or canned air to clean the rubber debris off the connectors. Let the solvent dry completely before you insert RAM.
Clean Memory Slot
Now that the modules are clean, it’s time to clean the memory slots. The memory slots are connected directly to the motherboard. So I do not recommend using any liquid solvent to clean them, instead clean them using pressurized air.
If you have all four memory slots occupied, dust and debris may not settle. But most users, including me, use two memory modules and the rest of the slots are empty.
You need to clean these slots thoroughly, especially if you plan on using them.
Note: If you are cleaning the slots using canned air, make sure you keep the PC case on its feet.
Place the nozzle on one end of the slot at an angle and spray.
Some dust particles may latch onto the surface and pressurized air may not work. In that case, try cleaning it using a soft brush.
Make sure that you do not bend or scratch the metal connectors inside the slot.
