In today’s digital world, desktop computers remain essential tools for both work and leisure. But even the most reliable machines can face occasional hiccups. The good news? You don’t always need a technician. With a little know-how, you can tackle many desktop issues yourself.
This blog will walk you through some of the most common desktop problems and show you how to troubleshoot them like a pro.
1. Computer Won’t Turn On
Problem:
You press the power button and… nothing happens.
Possible Fixes:
-
Check Power Supply: Make sure the power cable is plugged in securely. Try using a different power outlet.
-
Power Strip or UPS Issues: If you’re using a surge protector or UPS, test it by plugging your desktop directly into a wall outlet.
-
Hardware Check: Inspect the power button and internal cables. If the power supply unit (PSU) is faulty, it may need replacement.
-
Motherboard Lights: Check for indicator lights or sounds. No lights could mean a dead PSU or motherboard.
2. Slow Performance
Problem:
Your desktop boots up, but everything runs painfully slow.
Possible Fixes:
-
Background Programs: Open Task Manager (Ctrl + Shift + Esc) and check for unnecessary apps consuming RAM or CPU. Disable them at startup.
-
Disk Cleanup: Use the built-in Disk Cleanup tool or third-party apps to delete temporary files.

Uninstall Bloatware: Remove unused software that might be slowing down your system.
-
Upgrade RAM or SSD: For older desktops, a hardware upgrade can dramatically improve performance.
3. Random Shutdowns or Restarts
Problem:
Your computer shuts down or restarts without warning.
Possible Fixes:

Possible Fixes:
