Windows Keeps Freezing? 8 Fixes That Work
Your mouse stops moving. Or you can move it but nothing clicks. Or one program is "Not Responding" and dragging everything else down. Here's how to fix Windows freezing for good.
Quick fix for an active freeze
Press Ctrl + Shift + Esc to open Task Manager. Find anything labeled "Not Responding," right-click, End task. If the whole system is frozen, hold the power button for 10 seconds to force shutdown.
1. Check what's hogging resources
Open Task Manager (Ctrl+Shift+Esc). Click Performance. Watch CPU, Memory, and Disk during a freeze. If any are pegged at 100%, that's the bottleneck.
2. Close startup programs you don't need
Task Manager > Startup apps tab. Disable anything with "High" impact you don't use. Common targets: Spotify, Skype, Discord, OneDrive, manufacturer "helper" apps.
3. Update drivers, especially graphics
Right-click Start > Device Manager. Look for any device with a yellow warning icon. Right-click any graphics card > Update driver. Better: download direct from NVIDIA, AMD, or Intel's website.
4. Run System File Checker
Right-click Start > Terminal (Admin) or Command Prompt (Admin). Type sfc /scannow and press Enter. Takes 15-30 minutes. Repairs corrupted Windows files that cause freezes.
5. Check for malware
Open Windows Security > Virus & threat protection > Scan options > Full scan. Let it run (1-3 hours). Malware causes freezes by hogging CPU silently.
6. Check the hard drive
Right-click Start > Terminal (Admin). Type chkdsk /f /r and Enter. Type Y when prompted, restart. Runs at boot. Reports bad sectors if your drive is failing. Back up immediately if errors appear.
7. Make sure you have enough RAM
Open Task Manager > Performance > Memory. If "In use" is constantly above 80%, you're low on RAM. Either close apps you're not using, or consider adding more RAM (desktops, easy upgrade).
8. Check for overheating
Overheated CPUs throttle and freeze. Open the case (desktop) or bottom panel (laptop), blow out dust with canned air. Make sure fans are spinning. Check fan vents aren't blocked.
When to consider an upgrade
If your PC is more than 7 years old and you've done everything here, the hardware just can't keep up. A mid-range PC at $500-800 today vastly outperforms a high-end PC from 2017.
