Urgent computer boot problem 10, Urgent computer boot problem

Possible reasons: 1. If you have overclocked, then reverse the operation.

2. If there is no overclocking, it may be that the CMOS battery is dead. Then change the battery.

3. Maybe the BIOS is messed up, try discharging. See Attached.

3. Memory module. If there is too much dust, clean up the memory modules and slots.

Attached: "Discharge" on the motherboard. Here's how:

For most motherboards today, CMOS discharge jumpers are designed to facilitate the discharge operation of the user, which is the most commonly used CMOS discharge method. This discharge jumper is generally a three-pin that is located near the CMOS battery socket on the motherboard and comes with a battery discharge instructions. In the default state of the motherboard, the jumper cap will be connected to the pins marked "1" and "2", which can be known from the discharge instructions as "normal", that is, the normal use state.

To use the jumper to discharge, first use tweezers or other tools to pull the jumper cap from the pins "1" and "2", and then put it on the pins marked "2" and "3" to connect them, and the discharge description can tell that the status is "clear CMOS", that is, clear CMOS (as shown in the figure below). After a short period of contact, the user's manual settings in the BIOS can be erased and the motherboard can be restored to the default settings when the motherboard left the factory.

After discharging the CMOS, the jumper cap needs to be removed from the "2" and "3" pins, and then restored to the original "1" and "2" pins. Note that if you do not restore the jumper cap to its normal state, you will not be able to start the computer and there will be an alarm sound.

Although the method of taking out the power supply battery to discharge the CMOS has a certain success rate, it is not a panacea, for some motherboards, even if the power supply battery is taken out for a long time, the purpose of CMOS discharge cannot be achieved. There are many misunderstandings about the discharge of CMOS circuits, and computer DIYERS have also created many methods for the discharge of CMOS, such as "battery short-circuit method", "battery socket short-circuit method" and so on.

Open the case and find the jumper on the motherboard to discharge the CMOS (usually arranged near the coin cell battery), set it in the "CMOS discharge" position or cut off the battery, use a screwdriver to short the two reeds, and then reset the jumper or battery and restart the computer should be fine.

Reinstall the system! Clean up the chassis dust OK

Several possibilities:

1. According to what you said, the clock is always reset, which means that the motherboard battery is scrapped. And the reason why the computer always asks you for boot options is also the result of the motherboard battery failure and the loss of BIOS setting parameters.

2. There may be a problem with the motherboard hardware, some time ago my desktop also had the same problem as you, and finally found that there was a problem with the motherboard bridge.

You replace a motherboard battery (CR2032) first, if the problem is solved, it is fine, otherwise, clean and repair the motherboard.

Spend 5 yuan to buy a motherboard battery and replace it.

Press del to power on

Set the time and save the CMOS information and log out.

In fact, there are many problems, so I will list a few common ones.

Fault symptom 1: Turn on the power and press the power button, the computer has no movement. Analysis: At this time, the power supply should supply power to the motherboard and each hardware, and there is no movement to indicate that there is a problem with the power supply part. (including the motherboard power part).

1. If there is a problem with the mains power supply, please check whether the power socket is normal and whether the power cord is normal. 2. If there is a problem with the power supply of the case, please check whether there is a 5 volt standby voltage, whether the connection between the motherboard and the power supply is loose, if you can't measure the voltage, you can find a power supply to change it.

3. Motherboard problems, if there are no problems with the above two, then the possibility of motherboard failure is relatively large. First of all, check whether the connection between the motherboard and the boot button is loose and whether the switch is normal. You can try shorting the switch with a wire.

If not, you can only try replacing a motherboard.

Fault phenomenon 2: After turning on the power and pressing the power button, there is no movement on the computer.

Analysis: At this time, the power supply should supply power to the motherboard and each hardware, and there is no movement to indicate that there is a problem with the power supply part. (including the motherboard power part).

1. If there is a problem with the mains power supply, please check whether the power socket is normal and whether the power cord is normal.

2. If there is a problem with the power supply of the case, please check whether there is a 5 volt standby voltage, whether the connection between the motherboard and the power supply is loose, if you can't measure the voltage, you can find a power supply to change it.

3. Motherboard problems, if there are no problems with the above two, then the possibility of motherboard failure is relatively large.

There are several possibilities that exist:

1. The memory is not plugged in, or the graphics card is not plugged in!

2. There is a problem with the graphics card, or a connection cable problem!

3. Power supply problems, whether the power supply can not keep up!

4. The most headache, the motherboard problem, this thing is broken!!

5: Check whether the monitor wiring is connected to the graphics card.

6: The motherboard is broken.

7. There is a problem with the operating system.

8. The pins of the monitor connector.

9. Resolution issues.

Corresponding workaround:

1. Reinstall the memory module and graphics card, be sure to be stable!

2. Replace the graphics card.

3. Buckle the battery on the motherboard, wipe it with a clean eraser, and then install it tightly. If it doesn't work, just change the battery.

4. If the motherboard is broken, there is nothing to do but buy a new motherboard.

6. Reconnect the continuity between the monitor and the graphics card.

7. Find a professional to test the motherboard.

8. Reinstall the system.

9. The pin of the display connector.

10. Resolution problem, software problem is good, as long as it is not hardware, you can find another computer, connect to the display, set a lower resolution, and then take it to test!

Generally, the memory module is loose, just unplug it, wipe it, and plug it in again.

Or if the battery is oxidized, buckle it off and wipe it with a clean eraser.

And then the connection is loose.
