Reinsert the RAM stick and check if it works. You can also test by inserting it into another computer; if the RAM operates stably, then it's not the issue.
- For CPU: Clean and reseat the CPU, then test it. Alternatively, try installing it into another machine to see if it functions properly.
- For graphics card: Remove the card and boot the computer. If it runs smoothly, the issue lies with the VGA. You can also test it by installing it into another machine.
- For Computer Power Supply: Check if the computer's power supply is loose or damaged, and ensure the incoming power is stable.
- For Mainboard: If you lack knowledge about this component, it's best not to tinker with it. You can opt for warranty service or replacement if the mainboard is faulty.
4. Startup Sound Issues
Cause: Your computer may have dry or loose components like cooling fans, power supply, or a faulty HDD.
Resolution: Open the computer case, apply oil, and reassemble the fan blades for even distribution.
5. Excessive Heat Emission during Operation
Cause: Typically caused by dust accumulation in the computer, irregular CPU usage, dry thermal paste, frequent and continuous usage, or placing objects near heat sources.
Resolution: Clean the computer, apply thermal paste, and readjust the CPU for balance.
6. USB Not Detected or Unable to Open USB
Cause and Resolution
- Loose USB Connector: When plugging in a USB, the connection is unstable, causing the operating system to recognize the device but not its functionality, hence unable to open the USB.
- Faulty USB Firmware: You can refer to solutions for fixing USB formatting issues available in Mytour.
- USB Damaged or Cable Broken: It's advisable to purchase a new one.
Mainboard or Computer Port Issues: Check if there are any issues with the USB port. If not, it might be a Mainboard problem, which should be repaired or replaced under warranty.
