The operation method of the car computer tester is similar, and it is very easy to use. Connect the test computer and the car diagnostic interface. The method is: turn on the computer - select the car series to be tested - select the car model to be tested - select the system to be tested - —Read fault codes, data flow, component testing, matching. . . . In addition, if you still don't understand something, it is recommended to read the "operation guide" first, that is, the instruction manual! Comments to watch
Complete computer motherboard test card codes:
Generally speaking codes:
FF, 00, C0, D0, CF, F1 or nothing means the CPU failed
C1, C6, C3, D3, D4, D6, D8, B0, A7, E1 means that the memory is not enough
24, 25, 26, 01, 0A, 0B, 2A, 2B, 31 means that the graphics card is not enough
C1, C6, C3, 01, 02, this combination jumps in a loop Most of them are I/0 broken or BIOS refreshed
Extended information
Motherboard fault diagnosis card: It uses the detection results of the BIOS internal self-test program in the motherboard to display them one by one through the codes. Combined with the code meaning quick lookup table, it can be easily Quickly identify computer problems. Especially when the PC cannot boot the operating system, the screen is black, and the speaker does not beep, using this card can further reflect its convenience, allowing you to get twice the result with half the effort.
BIOS performs self-test on the system's circuit, memory, keyboard, video part, hard disk, floppy drive and other components every time it is turned on, analyzes the hard disk system configuration, and initializes the configured basic I/O settings. After normal operation, boot the operating system again. Its distinctive feature is that the critical components are tested first based on whether the monitor can display.
The failure of a key component forces the machine to shut down. If there is no cursor on the display, there will be no response on the screen. Then, test the non-critical components, continue to run the faulty machine, and insert the card into the expansion slot when the monitor has no display. According to the code displayed on the card, refer to which BIOS your machine belongs to, and then find out the cause and location of the fault represented by the code, you can clearly know where the fault is.
The pure water machine without computer control only has a booster pump and a water filter device. After connecting each equipment and pipeline according to the drawing, first turn on the tap water to test the pressure.
Make sure the pipelines are connected correctly, then you can connect according to the computer-less pure water machine wiring diagram below.1. The washing machine panel fails. First, check whether the plug and power supply of the washing machine are loose. Sometimes the power supply does not provide power, which will cause the panel to malfunction;
Solution: Check where the problem occurs and repair it in time. If the power contact is poor, the power socket must be replaced in time to avoid electric shock in future use. Safety is more important.
2. Take off the washing machine panel and check if there is any problem inside the panel. Check to see if the power switch is broken. The power supply is the source of power for the washing machine. If the switch is broken, the washing machine panel will malfunction;
Solution: If there is a problem with the panel, you can only repair it or replace it with a new motherboard.
3. Another reason is that some welding points in the panel are loose. Washing machines are all welded with tin. Some of them have been used for a long time, and the tin is oxidized, which will lead to poor contact and failure of the washing machine panel;
Solution Method: If the panel switch is broken, you need to ask some professional masters to replace the power switch. This is a relatively technical job that cannot be completed by yourself. If there are problems with some functional joints in the panel system, some professional tools can be used to repair them.
Computers have become an indispensable tool in our daily lives. However, during use, we often encounter various computer problems. . When our computer encounters a problem, how should we troubleshoot it? This article will provide some effective computer troubleshooting steps to help you solve computer problems quickly.
The first step is to check the computer’s hardware connection. Make sure all cables are plugged in, including power cords, monitor cables, USB devices, etc. If there is a broken connection, reinsert it and ensure a tight connection.
If the computer cannot start or there is obviously no power, you need to check whether the power supply is normal. First make sure the power outlet is powered, then make sure the power cord is securely connected. If the problem is still not resolved, the power supply itself may be faulty and it is recommended to try replacing the power supply.
If the computer cannot start normally, you can try to enter safe mode. During the startup process, press the F8 key (or other designated keys) to enter the boot menu and select safe mode to boot. Safe mode can help us troubleshoot problems caused by certain software or drivers.
If the computer starts normally but encounters software problems, we can consider checking the software updates and installation. Make sure that the operating system and related drivers are updated to the latest versions, and that installed software comes from trusted sources.
Sometimes computer problems can be caused by viruses or malware. Regularly conduct system scans with reliable anti-virus software and ensure that the virus database of the anti-virus software is up to date. If viruses or malware are found, remove them promptly.
If the problem persists, it may be caused by hardware failure. We can try to open the computer case and check whether the hardware components, such as memory modules, graphics cards, etc., are plugged in properly. If there is a problem, you can try replugging or replacing the hardware.
If none of the above steps can solve the problem, or you don’t know much about computer hardware and software, it is recommended to seek help from professional computer repair personnel. They have specialized equipment and technology to solve various computer problems.
I hope that through the content of this article, you can learn some basic computer troubleshooting steps to help you quickly solve computer problems. Thank you for reading!
First of all, make sure you are using the correct CPU, which means whether the CPU interface corresponds to your motherboard. For example, the B85 motherboard corresponds to the 1150CPU. However, fool-proof mouths can usually eliminate this problem. 775 and 771 are exceptions. Secondly, make sure your CPU is installed correctly and whether there are bent or even broken pins. It is recommended to insert a diagnostic card and determine the problem based on the diagnostic code.
Check the motherboard’s official website to see if the BIOS needs to be updated to support your new CPU, or your motherboard does not support the new CPU at all, even if they have the same interface. For example, 945 motherboard and P45 motherboard.
Insufficient power of the power supply can cause this problem. Memory sometimes can also cause this problem. Try plugging it in again or trying another one.
