If you’re searching for how to fix a slow computer, you’re not alone. Over time, even powerful PCs running Windows 10 or Windows 11 can start to lag. The good news? Most slowdowns are easy to fix without buying new hardware or paying a technician.
In this guide, you’ll learn how to fix a slow computer on Windows 10 and Windows 11 using practical, proven steps that actually work.
Why Is Your Computer Running So Slow?
Before jumping into fixes, it helps to understand what’s causing the problem. A slow computer usually isn’t broken—it’s overwhelmed.
Common reasons include:
-
Too many startup programs
-
Low disk space
-
Outdated software or drivers
-
Background apps using RAM
-
Malware or unwanted programs
The fix depends on the cause, so let’s tackle the most effective solutions first.
How to Fix a Slow Computer: Quick Wins That Work
1. Restart Your Computer Yes, Really
It sounds basic, but restarting clears temporary memory and stops background processes that pile up over time.
Why it helps:
-
Frees RAM
-
Ends stuck processes
-
Applies pending updates
If you haven’t restarted in days (or weeks), start here.
2. Disable Startup Programs Huge Speed Boost
Too many apps launching at startup is one of the biggest reasons Windows PCs slow down.

Malware doesn’t just steal data—it slows everything down.
What to do:
-
Run Windows Security → Full Scan
-
Remove suspicious or unknown programs
-
Avoid “free” tools from untrusted websites
A clean system is a fast system.
5. Update Windows and Drivers
Outdated software can cause performance issues, bugs, and compatibility problems.
Update steps:

Go to Settings → Windows Update
-
Install all recommended updates
-
Update graphics and chipset drivers
Updates often include performance improvements you don’t want to miss.
