- Too many programs starting automatically when you turn on your PC
- A pending Windows update stuck mid-install
- Low free storage space on your main drive
- Outdated or corrupted device drivers
- Malware or unwanted background programs using resources
Step-by-Step Fix
Restart properly
Don't just close the lid — use Start > Power > Restart. This clears out memory issues that 'Sleep' mode doesn't.
Check for Windows updates
Go to Settings > Windows Update > Check for updates. Install anything pending and restart again once it's done.
Free up disk space
Open Settings > System > Storage and run Storage Sense, or use Disk Cleanup to remove temporary files. Windows runs poorly with less than 10–15% free space.
Run the built-in troubleshooter
Go to Settings > System > Troubleshoot > Other troubleshooters, and run 'Windows Update' and 'System Maintenance'.
Check Task Manager for resource hogs
Press Ctrl+Shift+Esc, sort by CPU or Memory, and close anything unfamiliar or using excessive resources.
Disable unnecessary startup programs
In Task Manager, click the Startup Apps tab and disable anything you don't need running the moment you log in.
Scan for malware
Open Windows Security > Virus & threat protection > Quick scan. If it finds something, run a Full scan afterward.
Update your drivers
Open Device Manager, look for any device with a yellow warning icon, right-click it, and select Update driver.
Run System File Checker
Open Command Prompt as Administrator and type sfc /scannow, then press Enter. Let it finish — this repairs corrupted system files.
Consider a clean restart or reset
If nothing else works, Settings > System > Recovery > Reset this PC lets you reinstall Windows while keeping your personal files.
Still Not Fixed?
If your PC still won't boot, shows a blue screen repeatedly, or you're worried about losing important files during a reset, stop here — that's exactly the kind of situation where a second pair of eyes prevents a bigger problem.
