Computer hardware servicing involves the management of all computer components when they malfunction. In the past, significant money was required for servicing, but today, with the affordability of computers, many opt to buy new ones instead. With the ability to handle basic troubleshooting and Windows software setup, people often feel they no longer require hardware servicing. Consequently, neglected computers remain unusable, collecting dust due to lack of time or fear of damaging them.
Common PC or laptop issues requiring troubleshooting include:
- Power on, but no display on the monitor
- Zigzag lines or unusual colors on the screen upon startup
- Blue or black screens suddenly appearing
- Sluggish computer performance after running for some time
- Overheating of the computer body
- Internet browsing causes the PC to hang
- Excessive noise from the computer upon startup
- Issues with the DVD tray opening or closing repeatedly
- Failure to install operating systems like Windows or Linux
- Continuous restarting displaying the Windows logo
- Unexpected commands upon mouse clicks
- Keyboard displaying inverted letters
- Non-responsive mouse cursor
- Software installation or uninstallation failures
- When the touchscreen on a laptop or tablet becomes unresponsive, it might indicate a hardware issue or a driver malfunction. Troubleshooting involves checking for driver updates, cleaning the screen surface, or calibrating the touchscreen settings.
- Malfunctioning USB ports can hinder connectivity with external devices. Troubleshooting includes checking for physical damage, updating drivers, testing different devices, and verifying power supply to the ports.
- If the webcam doesn't work, it could be due to driver issues or hardware malfunctions. Troubleshooting involves checking device drivers, software settings, and physical connections. Additionally, privacy settings or security software might block the webcam's functionality.
- Users might face issues with sound output from speakers or headphones. Troubleshooting involves checking volume settings, verifying audio drivers, testing different audio devices, and ensuring proper connections.
- An overheating graphics card can cause display issues, sudden shutdowns, or performance problems. Troubleshooting includes cleaning dust from the card and the computer's internal components, checking cooling systems, and monitoring temperature levels.
- Users might experience erratic or imprecise movements of the mouse or touchpad. Troubleshooting involves adjusting sensitivity settings, cleaning the surface, updating drivers, or checking for physical damage.
- Problems with the keyboard, such as non-responsive keys or sticky keys, might arise due to hardware issues or software conflicts. Troubleshooting includes checking for driver updates, cleaning the keyboard, and testing with an external keyboard to diagnose the problem.
- Users might encounter issues with the display resolution, such as blurry or stretched images. Troubleshooting involves adjusting display settings, updating graphics drivers, and ensuring compatibility between the display and the graphics card.
- Issues related to power supply, such as sudden shutdowns or failure to turn on, can be caused by faulty power adapters, battery problems, or power supply units. Troubleshooting involves checking power sources, replacing adapters or batteries, and inspecting power cables for damage.
- Connectivity problems with Wi-Fi or Bluetooth devices can occur due to signal interference or hardware issues. Troubleshooting involves checking signal strength, changing network settings, updating drivers, and relocating the device to reduce interference.
