Step 1:

How did your PC stop working?

Did you spill water? Was it heating up? was the fan not spinning? was the screen purple or green? Most of the time when a personal computer stops working, it is because of a hardware issue. The most common hardware issues are a result of either water damage, excessive heat, or a fan not spinning. While these are the most common hardware issues, there are a variety of other potential problems that could be causing your personal computer to stop working. Other potential hardware problems that could be causing your personal computer to stop working include a faulty power supply, a faulty motherboard, or a faulty CPU. In some cases, a personal computer may also stop working due to a software issue, such as a virus or a driver conflict.

Step 2: Before Jumping in

First and foremost, before you go open up your PC and panic, Try to use a different power cord, try different wall plugs. Use other electronics to test that the power source is working. Check your monitor is working. You can try to plug your computer into different monitors or use a different cable.

Step 3: Getting ready

Now you have your initial inspection and gather the information you need, now it is time to get the right tool to work on your PC.  Get the right screwdriver; clean the table. These two simple tips will help you get the tool to work on your PC. The first step is to get the right screwdriver. There are two types of screwdrivers, a Phillips head, and a flat head. Phillips head screwdrivers are the most common type and can be found at most hardware stores. The second type of screwdriver is a flathead screwdriver. These are less common but can be found at some hardware stores.

The second tip is to clean the table. This will help you avoid getting dust and dirt on the tool. Dust and dirt can cause the tool to malfunction.

By following these two tips, you will be able to get the tool to work on your PC.

Step 4: Turn OFF the PC

Turn off the PC, remove the power cable off the back and hold the power switch for 30 seconds. 

STEP 5: Make yourself comfortable, find the right place to work

First, get comfortable. If you are not comfortable and confident, it is time to stop. It might be a cheap repair if you take it up to technicians, you can make the matter worse. Now you have to find a non-conducting surface to work on. Comfort is important when working on any type of repair, especially when it comes to electronics. Not only can you cause more damage to the device if you're not confident in your abilities, but you can also end up injuring yourself. Make sure you have a solid, non-conducting surface to work on before proceeding with any repairs.

STEP 6: Open up your case carefully and do a visual inspection

Open up your PC, and slowly remove the front case. There are different types of front cases. On a desktop, there is usually a big metal grate that covers the entirety of the front of the PChine. Modern computer case has tempered glass, remove it carefully and keep it in the corner, You don't want to break the glass. Now that the glass is off, you should be able to see all of the different hardware that makes up your computer. Everything should be plugged in correctly and nothing should look loose. Have a look at the fans and make sure they're not dusty.

While you have the case open, it's a good idea to check all of the cables and make sure they're plugged in correctly. Oftentimes, a loose cable can be the cause of a computer not working correctly. Once you've inspected everything and made sure everything is plugged in, you can close up the case and screw it back together. You can remove the cable and plug it back in. Make sure the fans are spinning, GPU is plugged in with a PCIe cable. See if there is any error light blinking on the board.

STEP 7: Reseat the GPU, RAM

Random access memory (RAM) is a storage device for your computer that is used to hold data that is being accessed by the CPU. The GPU, or graphics processing unit, is responsible for displaying images on your screen. If either of these parts is not functioning properly, it can have a serious impact on your computer's performance.

One of the most common problems that can occur with these parts is that they can become loose over time. This is often the result of vibrations from the computer's fan or from using the computer for extended periods. If you have noticed that your computer has been running slower than usual or that it has been crashing more frequently, it is likely that one of these parts has become loose and needs to be reseated.

While it may seem like a daunting task, reseating these parts is quite easy and only takes a few minutes. In most cases, you will only need a Phillips head screwdriver.

First, shut down your computer and unplug it from the power outlet. Then, open up the case and locate the RAM. It will usually be inserted into slots on the motherboard. Gently remove the RAM from its slots and set it aside. Next, locate the GPU. It will also be inserted into slots on the motherboard, but these will likely be different from the RAM slots. Remove the GPU and set it aside as well.

Once both of these parts have been removed, take a look at the slots they were inserted into. If you see any dust or debris, use a can of compressed air to clean it out. Then, line up the RAM with the slots and gently insert it back into place. Do the same with the GPU.

Once both of these parts have been reseated, close up the case and plug your computer back in. Try turning it on to see if the problem has been resolved. If it has, great! If not, you may need to move to the next step.

STEP 7: Do the re-wiring

The best way to rewire a PC is to first remove all the existing wires. Next, separate the different types of wires so that they are easier to identify. Then, arrange the wires in their new positions. Finally, replace the wires and screw everything back into place.

While this may seem like a daunting task, it is actually quite simple and only takes a few minutes to complete. The most important thing is to be careful and take your time. With a little patience and attention to detail, you can easily rewire your PC and get it running like new again. Also, try to remove the GPU from the board and connect it from the board and see if it works.

STEP 8: Check PSU (Power Supply Unit)

You can do a few things to ensure that your power supply is working properly. First, check the power cord to ensure that it is plugged into an outlet and that the outlet is receiving power. Next, check the power switch on the power supply to make sure that it is in the "on" position. Finally, check the connections between the power supply and the other components in your computer to ensure that they are secure. 

How to check if your Power Supply is bad?

One way to check is to simply listen to your computer. If you hear a buzzing or whining noise from your power supply, it could indicate that it is going bad. Another way to check is to look at the LEDs on your power supply. If they are dim or flickering, it could also be an indication of a problem.

If you suspect that your power supply is going bad, it is important to replace it as soon as possible. A bad power supply can cause serious damage to your computer, so it is better to be safe than sorry.

There is another way to check which requires a multimeter. Most power supplies have a four-pin connector that is used to connect to the motherboard. This connector has three voltages: +3.3 V, +5 V, and +12 V. You can use a multimeter to test these voltages to see if they are within the normal range. If it is not right, swap a power supply and see if it works. If it is right, move to the next step

STEP 9: Reseat and reapply the thermal paste in the CPU

CPUs are the brains of our computers, and as such, they generate a lot of heat. This heat needs to be properly dissipated in order to keep the CPU functioning properly. Otherwise, the CPU will overheat and potentially become damaged.

There are a few different ways to prevent CPU overheating. One is to make sure that your computer case has good airflow. This will help to ensure that heat can dissipate properly. Another is to use a CPU cooler. These are devices that attach to your CPU and help to dissipate heat.

There are a few different causes of CPU overheating. One is a lack of airflow. If your computer case is not well-ventilated, heat can build up inside and cause problems. Another is overclocking. This is when you artificially increase the clock speed of your CPU in order to make it faster. This can cause increased heat generation, which can lead to overheating.

CPU overheating is a serious problem that can lead to damage to your computer. Fortunately, there are a few things that you can do to prevent it. Make sure that your computer case has good airflow and consider using a CPU cooler. Overclocking your CPU can also lead to overheating, so be careful if you are doing this.

Enough theory, now let’s discuss what you want to do. First, take off the CPU fan carefully, clean it with alcohol, reapply the thermal paste and reseat the CPU and see if it turns on, if yes, run the PC, and monitor the CPU temperature to see if it is normal. Normal CPU temperature is 60-75 degree Celsius.  If works, that’s fine, if not swap the CPU and see if it work. Make sure to use a compatible CPU, Not all the CPUs are the same.

 STEP 10:

If nothing works, it might be the motherboard or more. Sometimes, a power surge can blow up the CPU, and motherboard at the same time. This is the order recommended by our technician. Change the motherboard, then change the motherboard and CPU, and change the CPU, motherboard, and power supply.
