Why Is My PC So Slow? Common Causes
Before we jump into the fixes, it’s helpful to understand why your PC might be slowing down. Common culprits include:

Outdated drivers or operating system

Now, let’s get to the fixes!
10 Easy Ways to Speed Up Your Slow PC
1. Restart Your Computer (The Simplest Fix!)
Sometimes, the easiest solution is the most effective. Restarting your PC clears temporary files, stops background processes, and refreshes system memory.
✅ How to do it:
-
Click Start > Power > Restart
-
Wait for your PC to reboot and check if performance improves
2. Uninstall Unnecessary Programs
Over time, unused programs pile up and slow down your system.
✅ How to do it (Windows):
-
Press Windows + R, type
appwiz.cpl, and hit Enter -
Sort by “Size” to see which apps take up the most space
-
Right-click and Uninstall programs you don’t need
3. Disable Startup Programs
Too many apps launching at startup can slow down your PC’s boot time.
✅ How to do it:
-
Press Ctrl + Shift + Esc to open Task Manager
