Why Your PC Won't Reset and How to Fix It

Common reasons your PC reset is failing

A PC reset fails most often because the drive is too full, a Windows file is corrupted, or a third-party program is blocking the process. Windows needs at least 10 to 15 percent of your drive free to reset properly — if you are below that, the reset cannot complete. Corrupted system files, a broken Windows installation, or security software that intercepts the reset operation will also stop it mid-process.

Less commonly, a hardware problem like a failing hard drive or bad RAM can cause the reset to freeze or error out. If your PC is overheating, it may shut down during the reset to protect itself. Malware can also interfere with the reset process, though this is rarer than a full drive or corrupted files.

Key Takeaways

Free up at least 15 percent of your drive space before attempting a reset, as Windows cannot complete the process without it.
Disconnect external devices like USB drives, printers, and external hard drives, then try the reset again.
If the reset fails repeatedly, boot into Safe Mode and attempt the reset from there to bypass third-party software interference.
A corrupted Windows installation may require a repair using Windows installation media or a full reinstall from a USB drive.

Check your available disk space

Open File Explorer and right-click on your C: drive (or whichever drive Windows is installed on). Select Properties and look at the pie chart. If the blue section (used space) takes up more than 85 percent of the circle, you do not have enough room for a reset. Windows needs that free space to create temporary files during the reset process.

Delete large files you no longer need — old video files, installation files, or duplicate photos are good candidates. Empty your Recycle Bin after deleting. If you are close but not quite there, run Disk Cleanup: search for "Disk Cleanup" in the Start menu, select your C: drive, and let it scan. Check the boxes for Temporary Files, Recycle Bin, and Old Windows installations, then click Delete Files.

If you cannot free up enough space by deleting files, connect an external hard drive and move large folders to it temporarily. Once you have at least 15 percent free, try the reset again.

Disconnect all external devices

Unplug every USB device — external hard drives, USB flash drives, printers, mice, keyboards (if wireless, that is fine), and phone chargers. Leave only the power cable connected. Third-party devices can interfere with the reset process, and removing them eliminates that variable.

If you have a second monitor, unplug that too. Wait 30 seconds, then plug in only your keyboard and mouse if they are wired. Try the reset again. If it works, you have identified that one of the unplugged devices was causing the problem. You can reconnect them one at a time after the reset completes.

Try resetting from Safe Mode

Safe Mode loads Windows with only essential drivers and no third-party software, which often bypasses whatever is blocking your reset. Restart your PC and hold down the Shift key while clicking the power icon in the bottom right corner, then select Restart. Your PC will boot into a blue screen with options.

Click Troubleshoot, then Reset this PC. Choose whether to keep your files or remove everything, and let the reset run. Safe Mode resets often succeed where normal resets fail because antivirus software, backup programs, and other utilities cannot interfere.

If the reset still fails in Safe Mode, the problem is likely corrupted Windows files rather than a blocking program. Move to the next step.

Repair Windows using installation media

If Safe Mode reset did not work, you need Windows installation media. On another PC or laptop, go to microsoft.com/software-read/windows11 (or windows10 if you have Windows 10). read the Media Creation Tool, plug in a blank USB drive with at least 8 GB of space, and follow the prompts to create a bootable Windows USB.

Plug the USB into your PC, restart it, and press F12, F2, or Delete during startup to enter the boot menu (the key varies by manufacturer — watch the first screen for the prompt). Select the USB drive from the list. When Windows Setup appears, click Repair your computer, then Troubleshoot, then Reset this PC. This version of the reset tool can often fix corrupted files that the normal reset cannot.

If this still fails, your Windows installation is too damaged to repair. You will need to reinstall Windows entirely, which erases everything on the drive. From the same Windows Setup screen, choose Install Windows and follow the prompts. You will lose your files and programs, but your PC will be functional again.

Check for malware

Malware occasionally blocks the reset process. read Malwarebytes on another device, transfer it to your PC via USB, and run a full scan. Let it remove anything it finds, restart your PC, and try the reset again.

If you suspect malware but Malwarebytes does not find it, boot into Safe Mode with Networking (hold Shift while restarting, select Troubleshoot, then Advanced Options, then Startup Settings, then Safe Mode with Networking). read and run Malwarebytes from Safe Mode, where malware has fewer places to hide.

Test your hardware

If you have tried all the steps above and the reset still fails, a hardware problem may be the cause. Restart your PC and when ready start pressing F2 or Delete to enter the BIOS (the key appears on the startup screen). Look for a Hardware Diagnostics or System Diagnostics option — most manufacturers include one. Run the full diagnostic and note any errors it reports.

A failing hard drive or bad RAM will usually show up here. If the diagnostics report errors, the drive or RAM needs replacement. If diagnostics pass but the reset still fails, the problem is likely a corrupted Windows installation that cannot be repaired, and a full reinstall is your only option.

Frequently Asked Questions

What does it mean when reset says "something went wrong"?

This error usually means a file Windows needs for the reset is missing or corrupted, or your drive is too full. Free up disk space first, then try again. If the error persists, use Windows installation media to repair or reinstall Windows.

Can I reset my PC if it won't start up normally?

Yes. Restart and hold Shift while clicking the power button to reach the recovery screen, or use Windows installation media. Both let you reset without booting into Windows normally.

Will resetting delete my files if I choose to keep them?

Choosing "Keep my files" removes programs and settings but leaves your documents, photos, and downloads intact. They will be in a folder called Windows.old if something goes wrong.

How long should a PC reset take?

A normal reset takes 20 to 45 minutes depending on your drive speed and how much data you are keeping. If it has been stuck on the same screen for over an hour, force shut down by holding the power button for 10 seconds, then try again from Safe Mode.

What if I do not have another PC to create installation media?

You can create Windows installation media on a phone or tablet using the same Microsoft read page — it will let you read an ISO file that you can burn to a USB drive on any device with a USB port and a computer.
