When you encounter the situation where the red light of the CPU of the assembled computer is on or the fan does not spin, you may be at a loss. PHP editor Yuzai brings you a detailed guide to provide in-depth analysis and solutions to these common problems. From discussing potential causes to providing step-by-step troubleshooting steps, this article will guide you through these problems and give your computer a new lease of life.
The red light on the computer motherboard cpu
1. The CPU or memory has poor contact. Check to see if reinstalling or replacing the CPU and memory can resolve the fault.
2. The working frequency of memory, PCI-E or PCI does not match the external frequency, and a fault occurs. Generally, a CMOS discharge is performed to restore the CMOS to its default settings. Turn on the phone and try again.
3. The most common fault is poor contact of the memory module. Pull out the memory module, sweep the memory slot with a brush, and try plugging and unplugging it several times.
The main function of the CPU fan is to dissipate heat. Of course, heat dissipation cannot only rely on the fan and the silicone coating on the CPU. First, check whether the independent power supply of the fan is disconnected. If the connection is normal, check whether it is the power supply of the fan. If the wire is short-circuited, then you can only buy a new fan and replace it. This fan is indispensable, especially when the weather is hot. If the CPU cooling fan does not work for a long time, the CPU may be burned out

1. Check the monitor and host connection cables
First make sure that the monitor’s power supply and adapter cable are properly connected to ensure that the monitor can operate normally and receive signals from the host. Make sure that it is not caused by The connection problem causes the display to become unresponsive;
2. Re-insert the memory module and graphics card
If the graphics card is inserted incorrectly or incompletely on the motherboard, it will cause the host to fail to operate normally and Send out a display signal, the same goes for the memory stick. Check the position of the graphics card and memory stick and re-plug it;
3. Clean the graphics card and memory stick
Use a small amount of alcohol to clean the graphics card and memory stick. Gold finger, so that the gold finger can be connected normally, and check the integrity of the gold finger to ensure that your graphics card and memory module can be used normally;
4. Clean the CPU fan
If Excessive dust on the CPU fan will cause serious heating, which may directly cause the computer to be unable to start. The fan must be removed, re-applied with silicone grease and reinstalled.
To be painted. The reason why the original finished computer does not need to be coated with silicone grease is that it has already been coated with silicone grease during assembly before leaving the factory, and you need to apply it yourself when assembling the computer. If it is not applied, it will affect the heat dissipation of the CPU, causing the computer to crash or even burning the CPU.
Because the role of silicone grease is to fill the invisible gap between the CPU surface and the radiator, so that the heat generated by the CPU is more efficiently conducted to the radiator, thereby reducing the heat generated when the CPU is running. This step must not be forgotten!
If you don’t play games or overclock frequently, you don’t need to buy an additional radiator. The one that comes with the boxed processor is enough.
But if you buy a bulk processor (in simple terms, it means the one without a packaging box~), or you often play games or even overclock, you have to buy a radiator and install it yourself. It is generally recommended to use a heat pipe tower radiator, which has low noise and good heat dissipation effect. Generally, a tower radiator with four heat pipes is enough. I recommend Kyushu Fengshen Xuanbing 400, a relatively famous radiator.
Can't. The CPU radiator is specially tailored for itself, and both the size design and the heat dissipation power consumption have been tested. The radiator of the power supply consumes a lot of power and cannot be replaced, and the power supply of the power supply is not matched. The power supply is the core of the entire computer's electricity consumption, and its degree of heat dissipation is much greater. The fan blades are also larger than those of CPU cooling fans.
1. Intel i7 series CPU is a better choice for computer assembly. 2. The reason is that the Intel i7 series CPU has higher performance and processing power and is suitable for high-demand applications and tasks. They typically have more cores and threads, higher clock frequencies, and larger cache capacities, which provide faster computing speeds and smoother multitasking. 3. In addition, the Intel i7 series CPU also has lower energy consumption and better heat dissipation performance, which can maintain the stable operation of the computer and good temperature control. This is very important for computers that run for long periods of time and are used under heavy load. In addition, Intel i7 series CPUs have better compatibility and support, and can be compatible with various motherboards and other hardware, providing better scalability and upgradeability. To sum up, choosing the Intel i7 series CPU can achieve better performance and stability, and is suitable for various demanding applications and tasks.
Choosing the right computer CPU for you depends on your usage and budget. Here are some popular CPU options:
Intel Core i9 Series: For high-performance computing and gaming.
AMD Ryzen 9 Series: Delivers exceptional multi-core performance for multitasking and content creation.
Intel Core i5 and AMD Ryzen 5 Series: Mid-range options suitable for most apps and games.
Intel Core i3 and AMD Ryzen 3 Series: For everyday tasks and lower budgets.
AMD Threadripper Series: Designed for high-end workstations and content creation.
The best choice depends on your needs. For gaming and multimedia, a high-performance CPU may be more suitable. For day-to-day tasks, mid-range or low-end CPUs will do the job. It is recommended to check out the latest CPU reviews and comparisons to make an informed choice.
When assembling a computer with a CPU and a motherboard, you need to consider the following configurations:
1. Compatibility of the CPU and the motherboard: First, make sure that the selected CPU and motherboard are compatible with each other. You can check the corresponding product parameters on the official websites of the CPU and motherboard to determine whether they are compatible.
2. CPU type: There are two common CPU brands on the market: Intel and AMD. Different brands may require different types of motherboards to support them. Therefore, you need to choose an adapted motherboard that corresponds to the selected CPU brand.
3. Clock frequency: The higher the CPU frequency, the faster the processor runs. But too high or too low will affect system performance stability. Choose the appropriate main frequency according to your actual needs.
4. Number of cores: Multiple cores can improve processing capabilities, especially for large-scale software or multi-tasking. If you use more complex or large-scale software, it is recommended to choose a processor with four cores or six cores or above.
5. Motherboard slot: There are currently two main types of CPU sockets on the market, namely Intel LGA and AMD AM4. You need to confirm the slot corresponding to the CPU you selected and select the corresponding type of motherboard.
6. Rated power: From the perspective of power supply, you also need to pay attention to whether the output power of the power supply meets the needs of the CPU.
7. Other considerations: In addition to the above mainstream configurations, there are other factors that need to be comprehensively considered, such as minicomputer needs, light-load office scenarios, computer gamers and other user demand factors.
In short, when choosing a CPU and a motherboard, you must consider comprehensive considerations such as performance matching, complete functions, compatibility, price, etc., and finally choose a configuration that suits you.
