How to simply check the hardware problem when the installation point is not on?

Many players have been installing computers for a long time, but they find that they don't light up when they turn on the computer. People don't know what's wrong. After all, there are many reasons for the failure of lighting up. Today, let's talk about how to eliminate hardware problems and successfully light up the computer.

Today, we talk about the CPU, motherboard, graphics card, memory, SSD and other main hardware separately. Here we exclude the basic problems such as unstable or wrong connection of power supply and display, and damage.

The first is that the power on point doesn't light up, the fan doesn't rotate, and all the hardware doesn't light up,At this time, first power off, find the CMOS battery on the motherboard, remove it and wait for a few minutes, then install it back and try to light it up again.


The second situation is that after power on, the fan turns and the hardware lights up, but the display does not light up. This requires checking several hardware one by one, and players can also conduct directional checking according to the debug light on the motherboard.

1. CPU / motherboard

If there is a debug light on the motherboard and the CPU is faulty,One is to check whether the CPU is installed correctly, the other is to check whether the pins on the CPU or motherboard are bent or broken,You can also try to press the CMOS reset button in the I / O area of the motherboard, or remove the CMOS battery after power failure.

Another possibility is that there is an update to the BIOS on the motherboard. At this time, of course, you need to download and install the latest BIOS first. You can download it on the Internet and install it according to the installation instructions of the new BIOS.

2. Graphics card

If you are using a stand-alone graphics card, you need to check whether the display cable is correctly plugged into the stand-alone display, not the display interface on the motherboard.

If you are using a CPU with a core display, and the indicator light on the keyboard is not on at this time, then unplug the monitor cable from the independent display, and unplug the independent display, and plug the cable into the motherboard.


One is that the graphics card does not have normal power supply. Confirm whether the power supply line of the graphics card is plugged in. Now some graphics cards, such as gamer and Xingyao Series in the RTX 30 series, are equipped with power indicator. If the external power supply line is connected correctly, the white light will be on, otherwise, the red light will be on, and the graphics card cannot be on normally;

Second, if the gold finger of the graphics card is oxidized or stained with dust, you can wipe it with an eraser and try to light it up again.

Finally, if it still doesn't light up, the graphics card may have been damaged. You can contact the after-sales service directly for repair.

3. Memory

First of all, if the memory overclocking is carried out in advance, it may be that the memory frequency exceeds the frequency limit specified by the motherboard, or the memory itself or the Constitution does not support UHF, you can try to enter the BIOS to reset the parameters;

Secondly, if there is a problem with the memory slot, generally speaking,On the motherboard with dual channel memory, the memory is preferentially inserted into the second memory slot close to the CPU,See the motherboard manual for details, but in this case, you can unplug all the memory, wipe the memory to eliminate the problem of gold finger oxidation, insert a single memory in the second slot, and then try to restart;


Next, if there is a problem with the memory module itself or a compatibility problem, you can try to replace the memory in the previous check.



5. Summary

(1) If there is a debug light on the motherboard to report an error, the player can basically check the hardware failure according to the corresponding instructions. However, if there is no debug light, most of the problems are memory and CPU problems because the boot point is not on. Priority should be given to these two problems, and then SSD and graphics card should be checked, corresponding to the common troubleshooting measures one by one.

(2) In addition to the hardware itself or the compatibility between the hardware, there are many hardware failures caused by players after overclocking the hardware. Although overclocking improves the performance of the hardware to a certain extent, players should also act appropriately.

Although the performance of CPU overclocking is obviously improved, the CPU, as the core hardware of the computer, is unstable, which is easy to affect the life of other hardware and system stability, and even lead to other hardware damage;

Although the general memory can also be overclocking, but still have to worry about the motherboard on the memory limit, and the potential and space to improve the frequency also depends on the size and constitution of the memory.

If players are worried about the instability of overclocking, they can also directly click XMP, which can also improve the memory performance. However, if the memory overclocking has high stability and great potential space, such as the shadow car Hof extreme DDR4 memory, because of the Samsung original b-die overclocking particles and high-quality physique, players can further explore higher frequencies.
