The motherboard diagnostic card shows what is the problem with L0

Motherboard 10 means: test DMA channel 0.

Cause: It may be that the motherboard or CPU is not working properly.

Solution: 1. First remove all parts of the computer except the CPU, and check whether the motherboard voltage, frequency doubling and external frequency settings are correct.

2. Then discharge the CMOS, and then turn on the machine to detect whether the fault is eliminated. If the fault persists, you can also remove the CPU from the socket on the motherboard, carefully clean the dust around the socket, and then install the CPU, and apply a certain pressure to ensure that the CPU and the socket are in close contact, and then install the heat sink properly, and then boot the test.

3. If the fault persists, it is recommended to replace the CPU for testing. In addition, this phenomenon can also be caused by a damaged motherboard BIOS, so if necessary, flash the motherboard BIOS and try again.

If the voltage is too high or too low, the power supply starts to protect the motherboard.

If FF or 00 is displayed directly when booted, it is true that the CPU is not working, and the reason can be found from the following eight aspects.

One. The ATX power supply is damaged, and a certain set of voltages supplied to the CPU is missing, and it is also known that the first liquid will appear ff or 00, two. Due to long-term thermal expansion and contraction, the solder joints under the CPU seat of the motherboard will be desoldered (solder joint cracking).

Three. Check if the electrolytic capacitor near the CPU has burst, four. The power triode near the CPU burned out, five. has been reappeared after a series of other **:"00"or"ff", the motherboard is OK.

If there is an error in the setting of CMOS, and it eventually appears"00"or"ff"。

Appears as soon as it is turned on"00"or"ff"or other start** and no change is the motherboard is not running.

Six. Check whether all the addresses & data connected to the BIOS are disconnected or short? Some.

The Control signal should also be checked, because if the Control signal cannot be sent out, even if the address is correct, the BIOS will not.

Data will be placed on the data bus.

Seven. 00 .The configuration of the system is displayed; Coming to control the ini19 boot load.

ff .Give the ini19 boot the control of the loading program, and the motherboard is OK.

Eight. Use the characters displayed on the motherboard diagnostic card to quickly determine what part is faulty.

Reason: The system is procedurally incorrect, resulting in an error in the loop of the boot assistant diagnostic card, which shows 00, and it is recommended to restore the system to an earlier point in time to solve the problem.

2.Then select Recover System Settings and Computer in the next interface. If your computer doesn't have the restore feature turned on, you may need to turn it on;

3.Then open System Restore, that is, click the button shown in the figure, if there is an account control, there will be a prompt, pass;

4.Then the wizard that restores the files and settings will begin, all you need to do is follow the wizard's prompts. Click Next directly;

5.Then, in the System Restore Point option, select a restore point, make sure that the selected restore point is the restore point when the system was normal before, because if it is an abnormal restore point, there will be problems;

6.After you make sure that it has no errors, click the Finish button to start the system restoration, the system restoration will restart, and then enter the relevant restore operation during the boot process.

.There are achievements in art, 55 points, 25 points are needed to reach the next level It seems that you are not familiar with the diagnostic card, if the diagnostic card shows 00 then it means that the CPU is not working, there are two possibilities, one is the problem of the CPU itself (this possibility is very small); One is that there is a problem with the motherboard (the second possibility is very high). It is recommended that you detach your CPU and put it on another motherboard to give it a try, and the problem will be clear at a glance.

In my judgment, there should be a problem with the hosting! You can try.

Motherboard diagnostic card is a detection and maintenance tool that can diagnose which part of the motherboard fault occurs approximately, and its working principle is to use the self-test program test results in the motherboard BIOS, which are displayed one by one through **, so that you can quickly know which part of the computer is not working, that is, you can quickly know which part of the computer is not working. Especially when the computer does not boot the operating system or the screen is black, using the diagnostic card can show the convenience or multiplier the effect.

The memory of the question has also been changed.

The question began to search for what said CPU and COMS, but touching the CPU has a temperature, and the COMS battery is also discharged when it is taken down, or is it directly displayed 00 when it is turned on, is it a problem with the memory slot?

or poor contact.

The question is not, the detection card is directly displayed 00 when it is turned on, there is no other process to answer, and there is a possibility that the system is faulty, and the system needs to be reinstalled to ask [cover face] [cover face] [cover face] and install what system can not be turned on, and answer a little bit.

What about the motherboard, have you checked the motherboard?

oo indicates that the motherboard is not detected to be operating properly.

Either it's all detected, or the graphics card doesn't detect it.

Unplug the memory and see what is displayed.

1 From a series of ** (excluding "00" and "ff") to "ff" or "00", then the motherboard self-test has passed, OK.

2 out of "00", and the code does not change, it means that the motherboard is not running, check whether the CPU is bad, the CPU jumper, or the CPU settings are correct, whether the power supply is normal, and whether the motherboard battery is moldy?

3.If you set it to not prompt errors in CMOS, then when you encounter a non-fatal failure, the diagnostic card will not stop and continue to go back until "00", the solution is to change the CMOS setting to prompt all errors and then turn on, then if there is a non-fatal failure, it will stop, and then troubleshoot according to **.

It may be that the CPU is in poor contact, and after detecting that the reset is normal, the digit will show "FF" or "00", which means that the CPU is being detected. If it is set on "FF" or "00", it means that the motherboard does not recognize the CPU, and if the CPU is passed, it will jump directly to "C1" and the memory detection will be displayed.

Generally 00, either the motherboard or the CPU

It is recommended that you try a different CPU.

Hope it helps!

Friends above, don't scare ff, it's normal, okay.

1. If it is from other ** to 00, the motherboard self-test has passed.

2. If 00 is displayed and the code does not change, the motherboard is not running, check the CPU, CPU jumper, CPU settings, power supply, and motherboard battery.

If the motherboard running light does not turn on, the motherboard is not running.

The CPU isn't working.

And FF is also the CPU is not working.

00 on boot. It means that the CPU is not working, and it is usually the motherboard hanging. Check the power supply.

If it turns to 00 at the end, it means that the system has been turned on, check whether it is plugged in.
