What should I do if my computer can't start when it's cold?

Winter is coming and the cold wind is biting. For computer users, difficulty in starting up the computer in cold weather has become a big problem. PHP editor Strawberry brings you a solution to the problem that the computer cannot be started in cold weather to help you easily solve this problem.

1. What should I do if the computer cannot be started in cold weather?

Poor contact

When the external environment is too low, thermal expansion and contraction will occur. When the solder joints between the components and the circuit board expand due to thermal expansion or contraction, cracks or contact failures will occur. When the computer is started in a cold environment, it needs an adaptation process.

Reduced conductivity

General home computers have a boot temperature between 5 degrees Celsius and 40 degrees Celsius. For every 10 degrees Celsius above the normal range, the computer's performance will drop by 25%. There is a battery on the computer motherboard. When the computer is turned on, the viscosity of the electrolyte inside the battery will decrease, the conductivity of the graphite will decrease, lithium ions will diffuse to the stone negative electrode, and lithium crystals will easily precipitate.

2. What should I do if the computer hard disk light does not light up and the computer cannot start?

1. There are many reasons why the hard disk light does not light up, and it is restarted repeatedly. That is, the computer cannot find the hard disk or the system boot file in the hard disk. Is it entered? For example, the basic input and output system is the bios. There will be a lot of English words in the system. If there is no interface, the computer will not turn on. It is recommended to disassemble the case and pull out the memory stick. Use an eraser to wipe off the black stuff on the gold edge. If it is not there, wipe it and plug it back in. If it still doesn't work, check to see if you have a discrete graphics card. There may be dust on it. Unplug it and plug it back in. Use a brush to gently sweep away the dust on the case and try again. 3. What should I do if the computer cannot start after plugging in the independent graphics card?

First of all, check whether your graphics card has an independent power supply. If the graphics card requires independent power supply and you have not connected it to the power supply, the computer will definitely not light up. In addition, it is not a problem that it does not light up. Has there been an alarm? Normally when the computer is turned on, it will make a beep sound, and some motherboards need to be shielded. 1. Is there a problem with the independent graphics card? Solution: You can try it on another computer to see if there is a fault;

2. The power supply is insufficient. Solution: Change to a power supply with a rated power of more than 350 watts;

3. The driver is not installed. Solution: Install the graphics card driver on the computer;

4. There is foreign matter in the graphics card slot. Solution: Clean the graphics card slot;

5. The gold finger of the independent graphics card is oxidized. Solution: Use an eraser to rub the gold finger;

6. Overclock the graphics card. Solution: Restore the graphics card frequency to factory settings. It turns out that only the integrated graphics card and the independent graphics card can be turned on.

4. The hard drive fails to boot and the computer cannot start. What should I do?

The disk boot fails. Is there something wrong with your hard drive? First check whether the hard drive cable is loose. It may also be that the hard disk boot file is damaged or lost due to a virus. If that doesn't work, why don't you just change the keyboard? Or borrow a COM port keyboard, use the boot disk to boot and repair, or you can reinstall the system, boot up, load the keyboard and set it in coms. Generally, press the del key at the beginning, and then in the interface that appears: usually the third option Search there and find the word 'USB KEYBORD', press + - to change it and then press F10 to save and restart

5. The computer CPU is very hot and the computer cannot start! what to do?

The consequences of host overheating may include burning out the CPU, burning out the motherboard, causing the computer to automatically restart, burning out the network card, burning out the power supply, etc. Cooling methods:

1) Check whether the fan in the chassis is running normally.

2) Clean the dust in the case (the correct method is to blow the dust with a bicycle pump).

3) Put a drop of sewing machine oil on the cooling fan bearing, which can effectively reduce the noise! Don't drop too much, just one drop will do.

4) If necessary, you can install a high-power CPU fan and purchase a radiator with better heat dissipation effect, such as Kyushu Fengshen, etc.

5) Install a chassis cooling fan (be sure to buy one with double ball bearings). (There is strong electromagnetic radiation in the chassis, which is harmful to the human body. It is recommended not to open the chassis cover to dissipate heat.) 6) Move the host to a well-ventilated place.

6. What should I do if my laptop cannot start?

If the laptop cannot start, it may be caused by the following reasons:

1. Power supply problem: Insufficient battery power or a faulty power adapter may cause the laptop to fail to start.

2. Hardware failure: Hardware failures such as memory modules, hard drives, and graphics cards can also cause the laptop to fail to start.

3. Software failure: Software failures such as operating system problems and driver corruption can also cause the laptop to fail to start.

For the situation where the laptop cannot start, you can take the following methods:

1. Check the power supply: First, you need to check whether the battery power is sufficient and whether the power adapter is working properly. You can try to replace the battery or adapter for testing.

2. Check the hardware: If the power supply is normal, you need to further check whether the hardware is faulty. You can try to disassemble the machine and check whether the memory module, hard disk, etc. are normal. If hardware needs to be replaced, it is recommended to replace it with accessories that are the same as the original hardware.

3. Check the software: If the hardware is normal, you can consider checking whether the software is faulty. You can try to enter safe mode or use the installation disk to repair.

It should be noted that you need to pay attention to the internal structure of the computer during operation to avoid greater losses caused by improper operation. If you do not handle it properly by yourself, it may cause greater losses. It is recommended to find a professional computer repairman for inspection.

7. What should I do if the computer cannot start after the rain has passed?

Poisoned. It is recommended to redo the system.

There are three temporary folders in the Windows Generally, users are mostly system service type software (such as Exchange Server). Therefore, there are very few files in this folder.

2. Computer user account temporary folder: C:Documents and Settings username Local SettingsTemp directory (default is a hidden directory)

This folder is where user-application software (such as winword) dumps temporary files. The purpose is to temporarily call and write.

8. What should I do if I accidentally modify the BIOS system and the computer cannot start?

Cause analysis: The main reason for entering the BIOS directly when booting is that there is a problem with the host BIOS settings. Some computer motherboards have many other functions added to make them more user-friendly during setup. When the BIOS settings are incorrect, restarting the computer will automatically enter the BIOS. Solution: Since it is caused by BIOS settings, you only need to set them in the BIOS to solve the problem. When the computer boots up and enters the BIOS, select Load Fail-safe Defaults, Load Optmized Defaults, Restore Defaults and other similar options. After selecting, press "F10" to save and exit.

9. What should I do if the fan turns on and off intermittently after the computer is turned on and the computer cannot start?

The computer cannot be turned on, and the CPU fan rotates intermittently. You can check from the following aspects:

1. The fan is dusty, causing it to not operate normally.

Solution: Remove the CPU fan and use a brush and hair dryer to remove dust accumulation on the fan. At the same time, the dust accumulated inside the chassis and on the motherboard can be removed. ​

2. The host power supply fails. Solution: Remove the power supply of the host computer and install it on another computer that can run normally. If it can run normally, it means there is no problem with the power supply; if it cannot run normally, it means the power supply is faulty and needs to be replaced with a new one. ​

3. Fan failure. Solution: Remove the CPU fan and install it on another computer that can run normally. If it can run normally, it means there is no problem with the fan; if it cannot run normally, it means the CPU fan is broken and needs to be replaced with a new one. ​

4. Mainboard failure. Solution: If the above three steps still do not solve the problem, you can remove a functioning host power supply and install it on the faulty computer. If the CPU fan still rotates intermittently, the motherboard may be faulty and it is recommended to send it for repair.
