My NZXT PC sat motionless before me, its power button mocking my futile attempts to bring it back to life.
A surge of frustration welled up inside me as I tried everything in my limited technical knowledge to solve the mystery.
So, I researched online and tried troubleshooting. After struggling for a few hours, I got it working back.
In this article, I’ll show you why your NZXT PC isn’t turning on and how you can fix it.
Let’s get started!
How to Fix NZXT PC Not Turning On
Try these possible solutions when your NZXT PC doesn’t turn on.
#1. Check PSU
To begin, you should inspect your power supply and check the power button on your PSU, which should be in its “on” position.
Next, your system should be connected to the power source securely. Check the power cord connected to the system; it should be inserted all the way into the port.
And the AC adapter should be firmly inserted into the power outlet/ socket. If cables are looking loose, you can reset the cable connection.
Unplug the power cable from both the AC power outlet and PC, then plug it back in by pushing it in firmly.
And then, turn on the system by connecting it to the monitor. If the system doesn’t turn on, you should test the PSU using the jumping method.
Here is how you can check the power supply:
1. Turn off your system and unplug all PSU cables except 24-pin and AC cables.
2. Then locate pins 16 and 17; count from left with the clip facing up and pins towards you.
3. Now, prepare a paperclip by bending it to the “U” shape and insert it into the 16 and 17th pins to jump the system.
4. Turn on the power supply.
5. Check whether the PSU fan turns on; it means the PSU is working correctly. If you know a multimeter, you can use it to check your PSU.
Once you’ve checked the PSU is usually functioning, you can attach it back to the motherboard and troubleshoot other hardware components.
#2. Troubleshoot Power Source
If the power supply isn’t the reason your PC will not turn on, you should inspect your power outlet or strip. If the wall outlet/ power strip is malfunctioning or not providing current, you should fix it to turn your PC on.
Firstly you can look for the power adapter plugged into the wall outlet and ensure it is inserted securely.
You should also remember to check the power strip to ensure it is switched on and plugged into the outlet securely.
Then you can test your power socket using a lamp or other electronic gadget. Plug the lamp into the socket and check if it turns on.
If the lamp doesn’t light up, your socket is faulty and requires to be fixed by an electric man. Until you get the outlet fixed, you can use another socket near your computer.
#3. Inspect Cables
Another thing you can consider is checking all external or internal cables. You should take a look at all the cables, such as; the power cord, display, or other USB cables.
All the cables should be connected securely to the PC; you can reinsert the loose cables. And then, you should take off the side panel of your PC to access the internal components.
Once you have removed the system cover, you should check all essential wires. Ensure the GPU, CPU, especially 24 pins and power cables, are securely connected.
The 24 pins cable is the main connection that flows electricity from the CPU to the motherboard/ system components.
As the cable isn’t firmly connected or the pins are broken, your PC can run into a problem. In this situation, you should get it checked by an expert.
#4. Faulty Power Button Cable
The power button is connected to the motherboard via a thin cable fitted with a two-pins connector. Your PC will not turn on if the connector isn’t seated properly or the wire is damaged.
So, you should check and reconnect your PC power button cable to resolve the problem. Open the computer cover and then trace the button cable from the front of your PC.
This is usually located in the bottom right corner of your motherboard. And the power button connector is labeled with “power SW or PWR SW.”
Then pull the connector out and check if it isn’t damaged or dirty. If it is faulty, you should replace it with a new one.
If the power on the switch is faulty or still not working, you should jump-start your PC. To do so, you should unplug the power cord from the outlet.
And then, take off the side cover from the system and remove the power button cables to reveal the pins.
Now you should use a straight screwdriver and touch the power on pins on the motherboard. Plug back the AC adapter into the socket if the PSU fan running your PC is turning on.
#5. CMOS Reset
CMOS battery powers your computer BIOS firmware which is responsible for booting up your PC and configuring data flow.
Sometimes a damaged or incorrectly inserted CMOS battery might prevent the computer from turning on.
So, you should check it and reinsert it properly into the battery slot. Take off the system cover and locate the coin cell.
Remove it from the motherboard and wait a few minutes. After a minute, reinsert it and turn on the PC to ensure it is working.
If the PC is still not turning on, you should replace the CMOS battery with a new one and insert it into the motherboard.
#6. Check your Display
If your PC is lighting up but doesn’t show anything on the monitor, it can be your display malfunctioning.
So, you should also check your monitor and ensure it is not the reason for your PC not working. Unplug the power adapter and display signals cable from the PC and monitor.
Attach the monitor to another device or PC to check if it works. However, if the display isn’t the reason, you should follow other solutions.
#7. Fix your RAM
The RAM is a temporary memory where your computer stores data and uses it to retrieve quickly. If you have faulty or incorrectly seated RAM, it will cause problems.
You should take off your computer cover and remove the RAM sticks from the motherboard. Insert them back into the memory slot to ensure they are seated in place.
Now turn your PC back on; if the system doesn’t turn on, you should test them individually.
Here is how you can do so:
1. Remove all the RAM sticks plugged into the motherboard.
2. Insert them one by one and check them by turning on your PC.
3. Then test them with a combination of two and repeat the process until you find the problem.
4. Once you’ve found the faulty RAM stick, you should troubleshoot it.
#8. Check GPU
If the problem persists with your NZXT PC, it can be due to a faulty GPU. Firstly you should check whether the GPU is correctly seated because it is a common problem with new builders.
Locate the GPU connectors unplug them, and then insert them back in by firmly pushing until you hear a “click” noise.
However, if reseating the GPU doesn’t help, the problem can be related to your GPU. You should check your system to check if it turns on without the GPU.
Remove the graphics card from the motherboard and plug the display cable from the monitor into the HDMI/ DP located on the motherboard.
Plug your PC back in and try to start it up; if the system starts loading a window, your GPU is faulty and needs to be checked by an expert.
#9. Contact Customer Support
If none of the above solutions has fixed your PC, you should carefully check it for any physical damage.
If it is damaged/ broken, you should get it checked by a professional or contact your NZXT device customer support.
