The motherboard self test is slow, and the motherboard self test time is very long

Start by determining what the detection time is long.

When the logo is turned on, press esc to see the self-test content.

If it is memory, check whether the memory is inserted into the first DIMM port.

If it is a hard disk, change the IDE or SATA interface of the unplugged device from Auto to None in the BIOS

They won't self-check.

The most important motherboard brand model is not said. It's equivalent to asking in vain.

You told me in hi that it was m3m78, it must have been a mistake. I found the model M3N78.

It's easy to know the model number. Another special feature of this motherboard. The network environment can be detected without entering the operating system.

It is estimated that you are because you have turned on this function, which causes the motherboard to detect the network environment for a few seconds after booting up, and then enter the self-test state. You need to go into the BIOS to turn off this feature. You need to find it in the BIOS yourself.

Turn this feature off.

Specifically, in the Tools item in the BIOS, close Express Gate and then turn off AI Net2.

As you said, turning on both will take 10 seconds to boot up and a long time to detect the state of the physical network during the boot process.

Right-click on My Computer -- Properties -- Hardware -- Device Manager -- IDE ATA Controller -- Major, Minor IDE Controllers -- Change all device types to None in Advanced Settings, and after restarting, you only need to turn the scroll bar one or two times to enter the system.

Enter the BIOS, select the first boot item as the hard disk (there are steps in the manual), select the optimal settings (if it is the most optimal setting, change it back to the basic settings), and then boot it up.

That's when the computer is testing for new hardware, which can be set in the BIOS so that the computer doesn't test the hardware every time it boots up, which can greatly speed up the boot speed.

In this way, you can disconnect the dot first, then remove the motherboard battery, wait 10 seconds before installing it, or you can just jump the jumper of the coms and turn it on.

If you can, by the way, plug in your data cable and memory.

The long motherboard self-test time is a problem with the computer BIOS, and it needs to be re-set and optimized.

Enter the BIOS to change the default settings to the optimized settings.

After turning on the computer or restarting the computer, the screen displays "cd??"., press the "DEL" key to enter the BIOS settings interface, and find LoadoprimumSettings in the interface that opens, which is the optimized setting for the factory BIOS.

The specific steps are as follows:

Tool Material: Take the Dell Optiplex 7070MT desktop as an example.

1. First of all, on the Dell Optiplex 7070MT desktop, press the power button to turn on the Dell Optiplex7070MT desktop.

2. Secondly, during the boot process of the Dell Optiplex 7070MT desktop, press the "DEL" key on the keyboard to enter the BIOS interface.

3. On the BIOS interface, select the "BIOSFEATURESSETUP" option in the left function options.

4. Then on the "BiosfeaturesSetup" subwindow, select the "QuickPowerOnSelfTest" option.

5. Finally, select the "QuickPowerOnSelfTest" option and select "Disabled".

1. Short: The system starts up normally.

2 Short General error, please set the CMOS parameters, re-set the incorrect options.

1 Long 2 Short RAM or motherboard error, replace the memory or motherboard.

1 long 2 short display or graphics card error.

1 long 3 short keyboard control error, check the motherboard.

1 long 9 short motherboard flash rom or eprom error, BIOS damage, replace flash rom

Long sound constantly The memory module is not plugged in or damaged, reinserted or replaced.

The power supply and monitor are not properly connected to the graphics card, check all plugs.

Repeat a short ring: There is a problem with the power supply.

Black screen There is a problem with the power supply.

The others are: 1 short memory refresh failure, memory refresh circuit failure on the motherboard, replacement memory module.

2. Short parity error, the first 64KB memory chip has a parity failure, set the memory ECC check option to disabled in the CMOS settings to solve the problem, but it is best to replace the memory module.

3 Short basic 64kb memory failed, memory chip check failed, replace memory.

4. Short clock error, timer timer on motherboard does not work.

5 Short CPU failure, the CPU on the motherboard produces a failure.

6 short A20 door failure, the keypad controller contains the A20 door switch failure.

7 Short CPU Exception Interrupt Error, the CPU on the motherboard produces an exception interrupt and cannot switch to protected mode.

8 Short Display memory error, no display memory on the graphics card or display memory error, replace the graphics card or video memory.

9. Short ROM check failed, and the ROM check value is different from the value recorded in the BIOS.

10 Short CMOS register read and write errors, Shutdown register failure in CMOS RAM.

11 Short cache error The external chche is corrupted, indicating an external cache failure.

1 long 3 short memory error, memory corruption, replacement.

1 long 8 short display test error, the monitor data cable is not plugged in well or the graphics card is not plugged in firmly.

After unplugging the memory, use an eraser to scrub the gold finger and put it back again, and take a look at the CMOS discharge.

Most of them can't pass the graphics card. Or memory!!

The BIOS model used by the computer can be seen from the BIOS chip or from the POST information, if you see the word AMI BIOS; If you see the word "award", it is award bios

1 Short: The system starts normally. Congratulations, there is nothing wrong with your machine.

2 Short: General error, please go to CMOS Setup and reset the incorrect options.

1 long and 1 short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. If it still doesn't work, you can only replace a memory module.

Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.

It is recommended to flash BIOS to give it a try!

If it doesn't work, use the test card to test and see how much ** is?

Take a test card and see where the self-test doesn't pass, it's it.。。

Take it and fix it.。。 It's not okay to do it all this Isn't it broken or what?

According to the situation you described, it may be caused by the aging of the motherboard.

The boss didn't do anything, just removed the motherboard and put it back on, and that's it! "

This situation is often caused by poor contact between the motherboard socket and the gold finger on the motherboard.

In the future, you can also try this practice - plug and unplug (if there is dust at the gold finger, you can wipe it with a clean eraser) in order to check for simple faults.

Sometimes many problems are not necessarily hardware failures, and you can also determine where the fault is in some simple ways; If you really can't solve the problem, it's not too late to send it to the repair shop, you say that

It is recommended that you change the motherboard, so as not to burn the CPU memory out of any problems.
