When your pc won’t turn on but motherboard light is on, the first thing you should do is check the power supply. If the power supply is working, then the next step is to check the motherboard. If the motherboard light is on, it means that the motherboard is getting power, but the computer still won’t turn on. In this article, we’ll show you how to troubleshoot a computer that won’t turn on but on power led motherboard.
Problem with PSU
The computer won’t turn on. It could be a problem with the PSU. If you’re not sure, you can test the PSU using a multimeter. If the PSU is working, it’s likely that there’s another problem with the computer.
Check the PSU connections
Your computer’s power supply unit, or PSU, is one of the most important components in your system. The PSU provides power to all of the other components, and if it fails, your system will not work. It is important to check the PSU connections to make sure they are all properly connected.
The 24-pin motherboard connector and the 4 8 CPU power cables should be connected properly. If there are any problems with the connections, it could cause the system to not work properly or even damage the components.
Problem with fan
The first thing you should do is check whether the power supply is the problem. If it’s not the power supply, there are a few other things you can check.
One possibility is that the fan isn’t working correctly and isn’t cooling the computer properly. This can cause the computer to overheat and shut down. If this is the problem, you can try cleaning or replacing the fan. Another possibility is that there’s something blocking the airflow inside the computer. This can also cause overheating and shutdowns. You can try cleaning out any dust or debris inside the computer to improve airflow.
Check for any IC fuse
A computer’s power supply is one of the most important pieces of hardware in the system. If it goes out, the system can’t function. One common problem with power supplies is that they can overheat.
When this happens, there may be a burning smell coming from the unit. If there is, the first thing you should do is check for any blown IC fuses. If there are any blown fuses, you’ll need to replace them with a new one.
Check PC power button
Most people think that the power button on their computer is either working or it’s not. It’s a simple on or off switch, right? Actually, the power button can do more than just turn the machine on and off. In fact, it’s possible to bypass the power button completely and turn the PC on and off with a different method.
Before you try any of these other methods, you should check to make sure that the power button itself is working correctly. To do this, you’ll need to open up your PC and take a look at the power led motherboard. There should be a couple of pins near the power button that are connected to a switch. When you press the power button, these pins are supposed to be disconnected from each other.
Reseat the memories
Memory is a key component in any computer, and when it’s not working properly, the whole system can be affected. Incompatible or faulty memory can cause the pc wont turn on but motherboard light is on. If this is the problem, the first thing you should try is reseating the memories. This means removing them from their sockets and putting them back in. Often, this is all it takes to get the system up and running again.
If reseating the memories doesn’t work, you may need to replace them. You can buy new memory from most computer stores or online retailers. Be sure to match the type of memory your PC requires (DDR2, DDR3, etc). Also, make sure you get the right amount of memory for your PC. Most PCs require between 1 and 4GB of memory.
GPU might be causing the issue
If you just installed a new GPU, there’s a good chance that’s the root of your PC not turning on. Graphics cards draw a lot of power, and if your PSU can’t handle the load, it might not turn on at all. Try to turn on your PC without the GPU installed and see if it boots up. If it does, then you know the issue is with your graphics card.
Are you experiencing a problem with your PC When the pc wont turn on but motherboard light is on? This could be due to any number of factors such as a bad power supply, failed motherboard, or faulty CPU. If you have already ruled out these possibilities, there are a few final things you can try before concluding that the motherboard is at fault.
One thing to check is if the power switch on the front of the case is working properly. If it is not, then you can use a jumper wire to short the power switch pins on the motherboard. Another possibility is that there is something blocking the airflow inside the case, preventing the fan from spinning. Make sure that all cables and components are securely in place and there are no obstructions blocking the fans.
The Power Button should be checked. An issue with the power button could cause your computer to not turn on, but the motherboard light will still be on. You may need to replace your power button if you can find no broken connections or faulty connections from the main source.
If your Windows PC won’t turn off, you should first rule out a faulty outlet or power supply . Also, you can check for display problems, abnormal BIOS settings, and beep codes. You can also disconnect non-essential devices, check for malware and loose components.
