There can be many reasons why you want to test the motherboard outside the CPU, but ‘How’ to do it properly is the question we are focusing on.
If you are wondering about what are the ways that let you have a thorough examination of your motherboard, you have landed onto the right page! In this article, we shall play up points for testing the motherboard without leaning on its central processing unit.
Basically, a motherboard is responsible to keep the components of a PC well connected to each other; hence its proper working is a must.
Besides, the diversified approach for a single problem makes things super-easy to opt for a solution. If you have been an apt PC user, you might have an idea about some of its working approaches as well. Therefore, how to test a motherboard without a CPU is something that is no longer a mystery!
The power connectors
For this method, you need to have 2 power connectors with 8 pins for the CPU power on the motherboard and the 24 for the motherboard power connector, respectively. However, the layout of pins depends if you have the latest power supply unit or older.
Before testing the motherboard without CPU, keep in mind that the 8 pin offers you 280 watts of power to the CPU, whereas the 4 pin connector consumes about 140 watts.
Make use of the wall socket
Another way to test your motherboard without CPU is to connect the power supply unit (PSU) directly into the wall socket. This is a valid way to keep things in control without inviting damage to the system.
While doing so, always ensure to have been placed on the non-conductive surface, moreover, grounded surface can make things highly perilous. Use rubber or plastic slippers before connecting the PSU to the socket.
Bench testing is one of the best methods to test your motherboard externally. In fact not just for the motherboards, but it is recommended for all PC’s components without its case or this solution, withdraw the motherboard from the CPU and place it onto the anti-static foam for anticipated safety purposes!
Now, test the motherboard the way you are looking up to it. Since it is a careful method, make sure you do not place the motherboard onto the metallic surface solely when the power is on. Coming in contact with the current or the shock can be fatal.
Making use of other peripherals
Other CPU components such as RAM, hard drive or graphics card can be useful while testing the motherboard. But it is advisable to keep off the hard drive so that your precious data won’t get lost, in case.
Use a multimeter
Testing the motherboard without a CPU is a technical thing when you are taking help from a multimeter. Therefore, before opting for this step is it important to have a professional around you. However, if you know the core insights of electronics it would be helpful for you.
The beep codes
You might have heard that alarming beeping sound coming out from the system, if it has the internal speaker or maybe you have paired the external speakers. These are the “beep codes” telling you that the connection to the motherboard to the CPU is in process and that the motherboard is working.
Moreover, if you do not have the RAM installed within it, the ‘’beep codes’’ will let out a sequence of beeping sound which means that the motherboard is in working state.
Beep tells you a lot. And each type of beep is different in meaning. Therefore, paying heed to the beep sound is also an important role in telling the problem. For example, single beeping sound refers to the issue with the memory; two times beeping indicates the issue with the motherboard, whereas the 5 times beeping sound means that the issue is most probably with the CPU.
POST (Power-on Self-Test) is one of the reliable methods for testing the motherboard without a CPU. However, whether or not you can test your mobo without CPU readily depends on the fact if the system offers you to do so or not. Only the latest and high-end motherboards come with this feature.
The POST feature is what lets you get to the core problem by the LEDs. It is best if you want to test the mobo without CPU assistance. In this testing, the fans should be working and turned on.
This is a testing proficiency I while power is turned on. It is the computer’s basic input/output system that checks out whether the peripherals devices are working that have been attached to it. So when you test the motherboard outside the CPU the LED lights should flash if it’s working.
Risk of testing Motherboard Without CPU
If you want to test the motherboard without CPU, you should know its ins and outs thoroughly to keep you from the danger of it. If you talk about the skillful persons, it can be a risky practice because you are highly likely to cause impairment to the whole motherboard unit, or maybe a specific part of it__ if you’re a little lucky!
Although, it is not common to damage the motherboard while testing it outside the CPU, yet if anything goes wrong be ready for purchasing the new mobo.
Bounties of Outside Testation
Since you are testing the motherboard without CPU, means it is a non-traditional method for which you will face some restrictions mainly you won’t be able to know about it:
Checking out of your motherboard is crucial when you are facing some PC working problem. Besides, if you have just purchased the system, and the motherboard has got some issues, it is better to check it on your own before taking it to the professional mechanic.
However, before opting for any of the methods, make sure you have enough knowledge about that or you have taken the precaution carefully.
