Many users have reported that their computer does not turn ON when they connect it to the Power outlet and switch the Power ON. There is quite a possibility that the motherboard is not getting Power from the socket. If you encounter this problem, please read this article for the resolutions.
Why is the motherboard not getting power?
The reasons for the motherboard not getting power could be many. These include no power from the background, hardware incompatibility, software incompatibility, etc. If the motherboard was receiving power previously, then the most probable cause is software incompatibility.
Motherboard is not getting Power
If the Motherboard is not getting Power when you turn on the system, you can try the following solutions to isolate the causes:
- Check the power supply
- Check the motherboard and CPU compatibility
- Check the RAM for improper insertion
- Check the graphics card and monitor
- Check for the connection cables
- Remove all peripherals connected to the computer
1] Check the power supply
If the motherboard is not receiving power, there is a high chance that there might not be any power from the source itself. This means that the power supply might be down from the socket itself. Other than this, the power cord could be problematic. So do the following.
- Check for the power supply in your building. Do other electrical equipments work fine?
- Check the power socket. Try connecting another electrical device to the same socket and verify.
- Check the power cord. Try connecting it to a different computer or use a tester tool.
2] Check the motherboard and CPU compatibility
When you assemble a computer, then all the components should be compatible with each other. To check for compatibility, you can check the website of the PC manufacturer. If you are using a branded motherboard, then please check the website of the motherboard manufacturer and only use compatible brands. We recommend using branded computers but if that is not possible, please ensure that every component is branded and compatible.
It should be noted that when you have booted the system at a later stage, you can note the system information to check for device compatibility later.
3] Check the RAM for improper insertion
If the RAM is not properly, you will not be able to switch ON your computer. It will be stuck at the POST stage. So, you must ensure the RAM is properly inserted and not loosely connected to the RAM slot. After this, check that if you are using an additional RAM (eg, a second or third RAM chip), the same should be compatible with the original system and motherboard.
4] Check the graphics card and monitor
How would you tell if the motherboard is receiving power or not? This can be judged by the display. But what if the display itself is not working?
To figure this out, check if the monitor is connected well to the system. Then, isolate the monitor and connect it to another PC to verify if it works. If the monitor works fine, then check the graphics card. It should be connected to the PC properly and should be compatible with the PC.
If any of the components mentioned above are incompatible, then you would have to replace them. If they are not connected properly, then reinsert them.
5] Check for the connection cables
Desktop PCs come with a tower and the components in the tower and connected through connecting cables. If the connecting cables are loose, the output components will not receive signals from the motherboard. In this case, the motherboard will not work. So, you can try reattaching the connecting cables.
6] Remove all peripherals connected to the computer
Peripherals connected to the computer could be the cause of the problem of the motherboard not receiving power. To isolate this cause, you can remove all the peripherals connected to your computer except for the keyboard (or the computer will get stuck at the POST stage) and then try powering ON the computer. If it works, then find the problematic peripheral through the hit and trials procedure.
What supplies power to the motherboard?
The power received through the power outlet is in the form of AC power. It is converted to DC power using a rectifier circuit. The rectifier circuit is then attached to the motherboard which is further connected to all other components in the system. If the rectifier circuit goes bad, then the motherboard will not receive power and the computer will not work.
