You can fix it yourself, the most common 5 major computer failures

For those who don't understand the computer, in the process of using the computer, we will inevitably encounter various computer failures. In the face of such a situation, the first idea that sprouted in my mind was to take it to the computer store for repair. In fact, some computer failures can be used normally by simply handling them. Why waste money? Then, after finishing the five major faults and solutions that are common to the computer, you can solve it yourself!

Fault 1: computer blue screen

1. Reason analysis: bad memory bar contact

Solution: Open the chassis to fix the memory module and perform dust removal on the computer. This way, the computer can run better. If the computer still has a blue screen, it may be a problem with the memory module. Consider replacing the memory module.

2. Cause analysis: Incompatible software installation leads to blue screen

Solution: If a blue screen appears after installing a software, you must uninstall this software. If the blue screen still appears after uninstalling, there are other reasons.

3, the cause analysis: computer poisoning caused by computer blue screen

Solution: If it is caused by a virus, you need to restart the computer and perform anti-virus operation. If the computer is still blue screen, you can consider reinstalling the system.

4, the cause analysis: computer overclocking caused the CPU to overheat or the internal hardware temperature is too high

Solution: At this time, check whether the CPU fan and the graphics card fan are rotating normally. If it is normal, the main consideration is to strengthen the heat dissipation.

Fault 2: No response after inserting the USB flash drive

Cause analysis: The computer itself is set or the USB flash drive is damaged.

Solution: Replace the interface. If the USB flash drive is still unresponsive, you can insert it into the USB interface of other computers. If it can be read normally on other computers, the problem lies in the computer settings. On the contrary, if it is on other computers. If it is still unreadable, there is a possibility that the U disk has a problem.

If it is the reason for the computer settings, open the "Run" dialog box and enter the command "gpedit.msc" to open the "Group Policy" manager. Expand Computer Configuration→ Manage Modules→ System, and double-click the Disable AutoPlay item. In the window that opens, set it to the "disabled" state and click "OK" to complete the setup.

Fault three: the computer temperature is too high, causing Caton

Analysis of the cause: There are too many programs running in the background, which is beyond the scope of the CPU. It may also be caused by poor heat dissipation in the computer case.

Solution: You can use some cleaning software to stop unnecessary programs in the background and clean up the system garbage. Regarding the heat dissipation of the chassis, we can do some simple maintenance, such as cleaning the dust inside the chassis, especially the CPU and the dust on the cooling fan.

Fault 4: The network cannot be used

1. Reason analysis: The NIC driver is not installed correctly.

Solution: Re-download and install the NIC driver, such as the driver wizard, etc.

2. Reason analysis: IP address conflict

Solution: 1 Click the network connection icon in the lower right corner of the computer and click "Open Network and Sharing Center"

2 In the new window that opens, click "Change Adapter Settings" in the top left corner.

3Open "Network Connection", right click on "Local Area Connection" and select "Properties" button

4 The Local Area Connection Properties dialog box is displayed. Double-click the "Internet Protocol Version 4 (TCP/IPv4)" option in the "This Connection Uses the Following Items" list.

5 The “Internet Protocol Version 4 (TCP/IPv4)” dialog box is displayed, select the “Use the following IP address” option, and then assign an IP address to the machine in the “IP Address” text box.

6 The “Internet Protocol Version 4 (TCP/IPv4)” dialog box is displayed, select the “Use the following IP address” option, and then assign an IP address to the machine in the “IP Address” text box.

7 After filling in, position the mouse cursor in the “Subnet Mask” text box and the system will automatically fill the subnet mask.

8 Enter the gateway address in the Default Gateway, which is the address of the router. Then click the "OK" button to save and you can set it successfully.

Fault 5: The computer cannot enter the system

Cause analysis: system crash or hard drive damage

Solution: Try to reinstall the system. If the hard disk is not recognized, the hard disk is damaged and the hard disk is replaced.
