Onda motherboard A770 and computer do not turn on problem 10

Most of them are memory, and they are not compatible with the motherboard, so it's good to buy a **!

There is also a possibility that your memory module is loose, open the case, and plug in the memory module to see if it can be solved.

Motherboard problems, mainly the CPU socket problem of the motherboard.

Analysis and solution of the solution that the Onda motherboard cannot be turned on: motherboard monitoring card. It can quickly detect which part of the motherboard is broken, which can help us narrow down the scope of troubleshooting, there are many problems with the motherboard monitoring card, and I just want to introduce you to a few common problems:

First of all, when the power is turned on, if the power light is not on, the display screen is black, and the other components do not react at all, then the average person will immediately think about whether there is a problem with the power supply, but in fact, this situation will also occur when the motherboard is broken. In a computer, the computer needs a starting device, generally speaking, this device is on the motherboard, which mainly has a starting capacitor, if this capacitor is damaged, there will be nothing response. This capacitance is very small, but it is easy to spot:

Pick up the motherboard and look closely, and you'll see a ferrous electrolytic capacitor, which is usually surrounded by a metal wire. With such obvious features, it should be easy to find. The solution is to replace a good capacitor.

This kind of problem is relatively common, and I have two friends who can't start the machine because of this problem.

It should be your motherboard self-test when the default detection of the floppy drive,Turn off the floppy drive,You boot into BOIS and then turn off the floppy drive to save and exit。

Because you have a wrong setting, you need to press F1, maybe the BIOS settings have a floppy disk, you can enter the BIOS and turn it off, or it may be some other problem, but you didn't give the details, I can't tell.

I can solve it, but I can't describe it, in the BIOS, it may be a floppy drive detection, because now there is basically no need for a floppy drive; It may also be that the hardware is incompatible, and the self-test encounters potential insecurity factors (which actually does not affect the use), and there is an option in the BIOS to avoid pressing F1 when encountering such problems. Please refer to the specific description of how to make it difficult to describe.

The common faults in general are:

1. The battery on the motherboard is dead. The main embodiment is that after booting, press F1, and the time display is abnormal after entering the system.

Solution: Replace the motherboard battery.

2. You set up a floppy drive to start, but you don't have a floppy drive.

Solution: A. Press del to enter the BIOS at boot, boot up the boot sequence, and turn off the floppy drive to boot.

b. Turn off the detection function of the floppy drive when it is turned on

Start the computer and press the [DEL] button to enter the main BIOS settings interface.

Select the "Advanced BIOS Features" setting item and press the Enter key to enter;

Set "Boot Up Floppy Seek" to "disabled" to turn off boot software detection.

It's basically caused by these two minor problems, and you can try it, hoping it can help you.

It should stay on the self-test screen, see if there is a prompt to press the F1 or DEL key or something under the screen, just follow the prompt to operate.

According to speculation, it should be stopped in the self-test state and not moving, right?

Resolution.

To boot up, you need to press the F2 key to enter, mainly because the settings in the BIOS do not match the real hardware data, which can be divided into the following situations:

1. In fact, there is no floppy drive or the floppy drive is broken, but there is a floppy drive in the BIOS, which leads to pressing F2 to continue.

2. It turns out that there are two hard disks, and they are set up as dual hard disks in the BIOS, but when you remove one of them, you forget to change the BIOS settings back, and this problem will also occur.

3. If the motherboard battery is out of power, it will also cause data loss, which will cause this failure.

4. Reboot the system, enter the BIOS settings, and find that the floppy drive is set to be coarse, but in fact there is no floppy drive in the chassis, after setting this item to none, troubleshooting.

There are many reasons why the machine crashes, and you can start with the software first, and then check the hardware if you can't solve it.

Hardware: 1. Check whether the CPU temperature is normal (generally not more than 70 degrees, the CPU will crash or slow down at high temperatures).

2. Try to reseat the memory;

3. After the first two steps of Sakura, the fault is still the same, please replace a memory to try;

4. After the first three steps, see if there is a condition to replace a CPU;

5. After the above operations, if the fault still cannot be eliminated, you can send the motherboard for repair to see if the problem can be solved by sending the motherboard for repair.
