How To Fix My PC That Won’t Turn On ?

It is a very irritating situation when you press the power icon of your PC and still nothing happens. Your computer has not turned on. You need no panic because dead computer is not beyond repair. Try some troubleshooting steps. Apply them to both desktops and laptops. This guide will help you walk through possible causes and solutions for your not turning on the PC.

Step 1: Check the Power Supply

In most cases, the primary thing you can be checking when your PC is not turning on is the power supply. Sometimes, glaring problems include the power cord or plug. Here is what you should do:

1.1 Ensure the Power Cord is Connected

If you happen to be using a power strip or surge protector, also check that it is powered on. For the ultimate diagnostics check: plug directly into the outlet, without surge protection. Then, continue on. Oh, don't forget! The power cord should be properly plugged into the wall outlet and the power supply of the PC.

1.2 Test the Power Supply

Check the power supply unit itself. In any case, your desktop will not power up if it's not working. Some have a switch on the back as well-be sure to check that it is set to "on." If the power supply is defective, you will also have to replace it.

Check if the battery is charged in case of laptops. If the laptop does not turn on even after plugging it into the charger, try another power adapter if available.

1.3 Confirm the Outlet is Working

If you're unsure if the outlet is working, test it. Plug in another device, like a lamp or phone charger.

Step 2: Inspect the Power Button and Case

If the power supply is functional, the next step is to ensure the power button itself is not the issue.

2.1 Check the Power Button

In power buttons, sometimes, the equipment has malfunctioned. Try pressing the power button for a few times and see if it responds. Most of the time, the switch gets stuck due to erosion or stuck occasionally. For a PC with a reset button, try pressing that to power the system on.

2.2 Inspect the PC Case

In desktop computers, the power button's wire to the motherboard could be loose or disconnected. If you're comfortable opening your PC case, check the power switch cables. They should be connected to the motherboard.

Step 3: Check for Hardware Issues

If the power button and supply seem fine, the problem may be other hardware. Faulty hardware can prevent your PC from turning on.

3.1 Look for Signs of Damage or Loose Connections

Open the case. Check for loose cables, disconnected parts, or damage. Try checking the motherboard's connections for desktops. Make sure all the wires, whether they're power, data, or other types, are indeed plugged properly. If the machine's a laptop, also check whether the RAM, hard disk, and some more components are these.

3.2 Remove External Devices

Often times, peripherals or external devices would inhibit a PC from booting up. Unplugging all external devices, including printers and USB drives. Now, try turning on your PC. If it comes on, one of the peripherals may be causing the issue.

3.3 Test the RAM

It is possible that faulty RAM might prevent the turn on of your PC. If you have multiple RAM sticks on the computer, try removing one and check if the computer could power up. If it can, then the removed RAM stick may very well be the one defective and should be replaced.

3.4 Disconnect the Hard Drive

An often malfunctioning hard drive may lead to your system failing to boot. Disconnect your hard drive or SSD from the motherboard and switch on the PC. If it turns on, the hard work might be from your storage device itself.

Step 4: Check the Motherboard and Power Supply for Faults

In case the diagnostic tests do not go favorably, then it is about time to take a look at either the motherboard or the power supply for faults as this is one troubleshooting step usually left to more advanced ones.

4.1 Test the Motherboard

Check the motherboard for damage. Look for burnt areas, blown capacitors, or corrosion. If you see any obvious damage, the motherboard may need to be replaced.

4.2 Use the Paperclip Test (Desktop Only)

There is also procedure of paper clip test to know whether a desktop power supply is in a working condition or not. This test involves creating a shorts between the green wire (PS_ON) and any black wire (COM) in the 24-pin ATX power supply connector. You could do this using a paper clip or small piece of wire. Power will not go into the power supply unit fan turnspit if the supply is bad and will not turn on.

Step 5: Reset the CMOS Battery

At times, it is possible that a wrong BIOS setting has disabled the computer from turning on. Resetting the CMOS battery will solve this problem, if it is the cause. It will reset everything to the default settings.

5.1 What Is the CMOS Battery?

The CMOS battery is a tiny round coin-cell battery. It is mounted on the motherboard. It powers the memory inside the CMOS on the motherboard. The memory, in turn, stores the BIOS settings.

5.2 How to Reset the CMOS Battery

Switch off the computer. Then, unplug it before resetting the CMOS battery. open the case-the desktop; access the battery compartment-on a laptop. Remove the CMOS battery for almost 5 minutes; replace it afterward. Then, switch on the system to find out whether it works.

Step 6: Seek Professional Help

If none of the above techniques work, you need to seek professional help. There could be situations that can only be diagnosed with the proper tools. Possibly a motherboard, CPU, or other important components failed.

Conclusion

Calm down. Then, use a systematic approach to troubleshoot your PC, which won't turn on. The first thing to do is check basics such as the power supply, power button, and external devices. Next, try more advanced troubleshooting. This includes inspecting hardware, resetting the CMOS, and testing the power supply. Still an issue? Call a technician or consult a repair service.
