Test the way of insufficient power supply of the graphics card:

1. Observe whether there is a follow-up, and confirm that some of them can't start the machine

2. Color resolution of observation system. After entering the system, the color resolution has been in a relatively low state, indicating that the power supply of the graphics card is insufficient

3. If the power supply of the graphics card is insufficient, the computer will often crash

First, we download and install aida64 software

extended data:

some devices can't work normally, the computer suddenly restarts in the process of working, can't start, can't install the operating system normally, etc. If the power supply is not good, your computer will burn down or restart frequently

solution to insufficient power supply of graphics card:

try to replace the power supply of other models, especially the procts with normal or slightly higher + 12V output. If the graphics card works normally after replacement, it indicates that the graphics card is allergic to the power supply voltage, that is, when the voltage is low to a certain threshold, it can not meet the requirements of the BIOS or driver for the power supply voltage, the fault will appear

in addition, the fluctuation of power supply voltage caused by the instability of mains voltage may also lead to the instability of graphics card and the occurrence of insufficient power supply. When there is a compatibility problem between the graphics card and the power supply, you can try to refresh the BIOS of the graphics card. If you can't solve the problem, you have to replace the power supply; If the mains voltage is unstable or often low, a wide range power supply or UPS can be used

1、 Test the way of insufficient power supply of the graphics card:

1. Observe whether there is a follow-up, and confirm that some of them can't start the machine

2. Color resolution of observation system. After entering the system, the color resolution has been in a relatively low state, indicating that the power supply of the graphics card is insufficient

3. If the power supply of the graphics card is insufficient, the computer will often crash

If the frequency of the graphics card is too high, and the core voltage of the graphics card is not increased correspondingly, the graphics card may be unstable. This intermittent failure to start up, and the maintenance of Jinshan computer is also one of the manifestations of instability. So if the graphics card has been overclocking, the frequency of the graphics card will be reced to the default setting, and the core voltage must be restored

2. Replace the power supply interface of the graphics card

there are some problems in the design of the 6-pin power supply interface of many power supply cards, so we can try a variety of combinations. Shanghai computer maintenance can make the best use of the power output capacity: two 6-pin interfaces are connected by 4-pin D-port

one 6-pin interface is connected by D-port, and the other still uses the original 6-pin interface of power supply; Both 6-pin connectors use a power source. Generally, this method can solve the problem if the fault is caused by the internal "single / double 12V output" of the power supply

In fact, the biggest reason for this kind of failure should still be in the power supply, especially for computers using high-end graphics cards, the power is usually quite large when starting. If the peak power of the power supply is just at this threshold, it may lead to the situation that sometimes it can be started and sometimes it cannot be started. Therefore, it is necessary to replace a higher power supply

the general gtx470 and above graphics card, with a high-frequency four core processor platform, need more than 600W rated power supply, and HD5850 and above graphics card, with a high-frequency four core processor platform, also need at least 550W power supply

4. Replace the graphics card slot and DVI interface

nowadays, the middle and high-end motherboards generally have two PCI slots, and different PCI slots will have different power supply and bandwidth. First try to change the graphics card to another PCI slot to see if it can return to normal. Secondly, change the DVI cable to another interface

it should be noted that before replacing the PCI slot or DVI interface, these interfaces must be cleaned once to avoid the influence of accumulated st inside

5. Upgrade the main board BIOS and restore it to the default setting

although the probability of this problem caused by the main board BIOS is quite small, it can not be ruled out, especially for some second-line brands of main boards, Shanghai Changning computer maintenance is more likely to cause various faults because of the bug in the BIOS. So try to upgrade the BIOS to the latest version as much as possible. After upgrading, do not do any operation. Leave the BIOS in the default state to see if the computer can start normally

if the power supply is insufficient, it is most likely to cause the system to fail to start or the computer to restart repeatedly. This situation generally occurs after the hardware upgrade. After the hardware upgrade, the overall power consumption of the platform is greatly increased, while the user's original power supply is not upgraded, resulting in the problem of insufficient success rate

Common Troubleshooting of computer graphics card:

fault phenomenon: graphics card false soldering, not limited to particles or display core itself, causes splash screen

graphics card splash screen symptom is a common computer fault, which may occur all the time. In the face of graphics card screen problems, most users do not know the reason, usually will be in a hurry, or even replace the original normal hardware

There may be many reasons for this, but it is mainly related to several core components of the graphics card. The damage of the display core, as well as the soldering and desoldering of the video memory, may cause the splash screen, because the material used to generate the picture is not read correctly in the video memory, so the texture and map cannot be loaded correctly. In addition to the reasons of the graphics card itself, the core / video memory overheated caused by the super graphics card, and the drive problem may also cause the splash screen, but these are a little easier to deal with

However, it is troublesome to deal with the damage of the display core and the false soldering and desoldering of the display memory. Even the false soldering of the lowest level of the display memory generally needs BGA welding station to solve, which is relatively lacking for ordinary people

solution:

if it's just a driver problem, just update the driver again. Unfortunately, in case of false soldering or desoldering, you should first apply to the manufacturer ring the warranty period. If even the warranty period has passed, it is recommended to send the video card to a professional organization such as Sunway express for repair. Although it is simply a process of re soldering and stable condensation, there are also cases of video card repair, but it can not guarantee 100% repair rate, I can't do it. I have to replace it with a new one

5. It is recommended to change to a high-power one, 350 to 400.

6. Power = voltage × If the current or voltage is low, it must be very high. It's easy to understand that integrated circuits and chips are generally low voltage and high current

7. The main board temperature sensor is not accurate and cannot be solved, which is a hardware problem.
