Essential Tips for Computer Repair

As college students head into winter break, some may take the opportunity to work and save up for a laptop. So what should we do if the computer has issues? Here, the teacher shares some basic knowledge and tips for computer repair, helping you say goodbye to being a novice!

Computer Repair Tips

Problem 1: High Processor Temperature Causing Frequent Crashes

　　Problem: The computer slows down after starting and often crashes or restarts unexpectedly.

　　Solution: After ruling out viruses and improper use, check the processor and memory. The performance of the processor is a common cause of crashes. If the processor’s temperature is too high, it can lead to crashes or restarts. Consider replacing with a better cooling fan to address the high temperature issue.

Problem 2: Thermal Paste Causing Increased Processor Temperature

Computer Repair Tips

　　Problem: To improve heat dissipation, a lot of thermal paste was applied between the chip surface and the heat sink, but the processor’s temperature did not decrease, instead, it increased.

　　Solution: Thermal paste is used to enhance heat dissipation. The correct method is to apply a thin layer on the processor chip surface, just enough to cover it. Applying too much is counterproductive as it hinders heat conduction and can absorb dust, which significantly affects cooling performance.

Problem 3: Clicking Sounds Inside the Case When Powered On

　　Problem: A newly assembled computer works fine, but there are frequent clicking sounds from inside the case.

　　Solution: It is likely that the processor’s cooling fan is hitting the data cables inside the case. Open the case and tidy up the cables to resolve the issue.

Problem 4: Overclocking the Processor Leading to Blue Screens

　　Problem: After overclocking the processor, the Windows system frequently shows blue screens, and programs cannot be closed normally, requiring a restart.

　　Solution: Change the processor’s overclocking settings back to default. If you want to overclock, do it gradually to find a suitable value.

Computer Repair Tips

　　Computer crashes are a headache for all users, but they are unavoidable. However, there are many effective ways to reduce crashes, and these methods can be found in our daily computer usage. Here, we have gathered some common causes of crashes and prevention methods, hoping to help you.

1. Avoid Overclocking the Processor Too High

　　Modern processors and graphics cards have good overclocking capabilities due to new manufacturing processes, making high-frequency and overclocked processors popular. However, while you enjoy the speed from overclocking, crashes may lurk silently, threatening your computer.

　　Overclocking can easily lead to system instability and even crashes. If crashes occur due to overclocking, it should be promptly reduced, or the rated working frequency should be restored to ensure stable computer operation.

2. Be Careful When Removing Hardware

　　Be careful when forcibly removing hardware to avoid poor contact with the motherboard. Some friends frequently insert and remove cards, which can easily lead to poor contact and cause crashes. After replacing the processor, ensure it is properly seated. Some crashes during startup are due to improper seating of the processor.

3. Proper BIOS Settings

Computer Repair Tips

　　Among the many ways to reduce computer crashes, one term frequently mentioned is “BIOS.” Although optimal BIOS settings are encouraged, the so-called optimal can be relative. Sometimes, the optimal settings can lead to startup or operational crashes.

　　If crashes occur due to improper BIOS settings, restore the BIOS to factory default settings immediately. Also, before upgrading the motherboard or graphics card BIOS, ensure the version number matches the model, and it’s advisable to back up the original version just in case.

4. Software Not Properly Closed Cannot Shut Down

　　When using software that has not closed properly, do not shut down, as this may damage system files and lead to crashes. Additionally, when prompted about overwriting files during software installation, it is best not to overwrite. System files are usually the most stable and should not be overwritten based on the order of time.

5. Clean Dust from the Case Regularly

Computer Repair Tips

　　Dust accumulates in the case over time, which can severely affect cooling performance. Dust can also cause short circuits when it contacts the circuit board, leading to crashes.

　　Additionally, try to avoid using pirated software, as these may contain hidden dangers.

　　During computer use, many unexpected issues may arise, which can be caused by software or hardware problems, or other reasons… So how should we respond to these unexpected computer issues? Don’t panic, please see below:

Encountering a Power Outage

　　Analysis: This is caused by a sudden power outage. Voltage fluctuations from a power outage can impact computer hardware chips, circuits, and resistors. If you were performing disk read/write operations during the power outage, it could cause bad sectors, or if you were writing a document, data could be lost.

　　Solution: When assembling a computer, choose a reputable power supply to minimize the adverse effects of voltage fluctuations on hardware. After a power outage, turn off all power to prevent the monitor power from starting simultaneously when power is restored, which could damage hardware. If financially feasible, consider acquiring an UPS for temporary power protection.

Automatic Shutdown

　　Phenomenon: The computer suddenly shuts down or restarts during normal operation.

　　Analysis: Modern motherboards have temperature monitoring functions for processors. If the processor temperature exceeds the threshold set in the motherboard BIOS, the motherboard will automatically cut off power to protect the hardware. Additionally, power management settings and antivirus software can also cause this phenomenon.

Computer Repair Tips

　　First, the computer being silent may seem simple, but sometimes the issue is complex, involving both hardware and software aspects.

　　Therefore, first identify the cause, whether it is a software or hardware issue, and then take targeted measures. Never act without knowing the cause, as that could paralyze the system and create significant problems. Below are some solutions for resolving the silent computer issue:

　　1. Check if the sound card, connection cables, and speakers are properly connected; run antivirus software to scan for viruses.

　　2. Right-click “Computer” — “Properties” — “Hardware” — “Device Manager,” then check “Sound, video and game controllers” for issues. If there are yellow exclamation marks, reinstall the device drivers to resolve the issue.

　　3. If there is sound but no speaker icon, open Control Panel — Sound and Audio Devices — Volume, and check the box to display the volume icon in the taskbar.

　　4. If there is no sound and no speaker icon, open Control Panel — Add or Remove Programs — Add/Remove Windows Components, check the box for “Accessories and Tools,” click “Next,” and then restart the system to prompt installation of new hardware.

　　5. Double-click the speaker icon — Options — Properties — check the box for “Microphone” to adjust the settings. Click on the speaker icon in the bottom right corner, find the microphone option, and adjust it accordingly.

　　6. Uninstall the sound card driver and reinstall or update the audio driver.

Computer Repair Tips

　　7. If you encounter a message stating “Cannot find AC chip” while installing the sound card driver, it could be due to a virus, accidental deletion of the driver, or software conflicts. The solution is to reinstall the operating system and drivers.

　　8. Sometimes, simply waiting a while after shutting down and restarting can resolve sound issues automatically.

　　10. Go to Start — Control Panel — Sound and Audio Devices — Sound, to check if it is set to mute, and select Windows default.

　　11. Click Start — Run, type regedit and press Enter to open the registry. Navigate to HKEY-CURRENT-USER, then click on ControlPanel, and change the value of Beep in Sound from No to Yes, then restart to hear the startup and shutdown sounds again.

　　12. If needed, delete the existing user account and create a new one. This may resolve the issue caused by a corrupted user profile. You can start by enabling the guest user, then restart to see if there are sounds during startup and shutdown. If so, create a new administrator account, and follow the prompts to delete the problematic account. During deletion, you will be prompted to keep the original account’s files; it is advisable to back up bookmarks and folders from the start menu before deleting. After that, you can copy them back.

　　With this, everything should be clear and convenient, saving a lot of time. So make sure to read carefully!!!
