Why is my computer stuck on the startup screen?

It can be frustrating when your computer gets stuck on the startup screen and won’t fully boot up. There are several potential causes for this problem, but the good news is there are also a number of troubleshooting steps you can take to try and get your PC back up and running.

Common Causes

Some of the most common reasons a computer might get stuck on the startup screen include:

  • Corrupted system files – Essential system files like bootloaders can become corrupted and prevent startup.
  • Faulty hardware – Issues with components like the hard drive, RAM, or graphics card could result in failure to boot.
  • Improper shutdown – Forcibly powering off the computer without properly shutting down can sometimes cause startup problems.
  • Software conflicts – Incompatible or buggy software programs can sometimes interfere with the boot process.
  • Virus/malware infection – Malicious software is designed specifically to disrupt normal computer operation.

Troubleshooting Steps

If your computer is stuck on the startup/boot screen, here are some of the basic troubleshooting steps you can take:

  1. Force restart your computer – Press and hold the power button for at least 10 seconds to force a hard reboot. This can clear any temporary glitches.
  2. Boot into Safe Mode – Restart your PC and press F8 on the boot screen to boot into minimal Safe Mode.
  3. Check connections – Make sure all cables, drives, and components are properly connected.
  4. Disable peripheral devices – Unplug any unnecessary USB, printers, or other devices during startup.
  5. Start in Clean Boot state – Boot with only essential system services/startup programs enabled.

If the basic troubleshooting steps don’t resolve the startup issue, you’ll need to dig deeper.

Advanced Troubleshooting

For more stubborn startup problems, advanced troubleshooting may be required:

  • Access Advanced Startup Options – Get to the Windows Recovery Environment to access startup repair tools.
  • Use Startup Repair – Automatically diagnose and fix startup issues.
  • System Restore – Roll back system files to an earlier restore point.
  • Startup Settings – Change settings that affect startup like boot mode.
  • System File Checker – Scan for and restore corrupted system files.
  • Clean Boot – Boot with only the bare minimum system services and software enabled.

These tools can be accessed through the Advanced Startup Options screen. Repeatedly press F8 or Shift+F8 on boot to access this screen.

Common Solutions

Here are some of the most common specific solutions that resolve issues with a computer stuck on the startup/boot screen:

Fix Corrupted System Files

Corrupted Windows system files like bootloaders are a very common cause of startup problems. Running System File Checker (SFC) can scan for and replace corrupted files:

  1. Boot to Advanced Startup Options
  2. Open a Command Prompt
  3. Run sfc /scannow
  4. Restart your PC

Repair Hard Drive Errors

Errors on your primary hard drive can also stop startup. Use CHKDSK to detect and repair hard drive problems:

  1. Access Advanced Startup Options
  2. Choose Troubleshoot > Advanced Options
  3. Select Command Prompt
  4. Enter chkdsk C: /f to repair drive errors
  5. Restart your PC

Start in Safe Mode

Booting into minimal Safe Mode can help isolate software and driver conflicts causing startup failure.

  1. Force restart your PC
  2. As it boots, press and hold F8
  3. Select Safe Mode
  4. Sign in and uninstall recently added programs
  5. Restart back into normal mode

Disable Incompatible Programs

If a particular program is preventing system boot, use System Configuration or MSCONFIG to disable startup programs.

  1. Access Advanced Startup Options
  2. Choose Troubleshoot > Advanced Options
  3. Open Command Prompt
  4. Type msconfig and select System Configuration
  5. Go to the Startup tab and uncheck suspicious programs
  6. Restart your PC normally

Roll Back Recent Changes

If startup problems started after a driver, Windows, or software update, rolling back changes often helps.

  • Use System Restore to revert your system files and settings to an earlier restore point before the issues began.
  • Boot to Safe Mode and uninstall recently updated programs.
  • Roll back updated drivers in Device Manager.

Preventing Startup Problems

While startup problems can never be avoided completely, there are things you can do to help prevent them:

  • Always use proper shutdown procedures – don’t force power off.
  • Be careful when installing new software – only use trusted programs.
  • Keep your antivirus updated and scan regularly.
  • Check for and install Windows updates promptly.
  • Avoid cluttering up your PC startup programs in Task Manager.
  • Monitor your hard drive health with utilities like CHKDSK.

Following best practices like these can help minimize startup failures caused by software conflicts or system file corruption.

When to Seek Professional Help

If you’ve exhausted all the basic and advanced troubleshooting steps but your PC still fails to boot properly, it’s probably time to seek professional help. A computer technician has specialized tools and knowledge to diagnose stubborn hardware and software faults causing startup failure.

Signs it’s time to take your computer to a repair shop include:

  • Startup problems persist after trying all standard troubleshooting.
  • You lack the technical knowledge to use advanced tools like System File Checker.
  • An error message indicates a component like the hard drive or RAM has failed.
  • Startup failure follows a serious problem like spill damage or overheating.
  • You don’t have access to Windows restore points or recovery tools.

Technicians can perform hard drive data recovery if needed, diagnosing any underlying hardware faults allowing the operating system to load.


Computer startup problems can arise for different reasons, but following some basic troubleshooting steps can often identify and resolve the issue. Diagnosing the cause of the problem is key – whether it stems from corrupted files, faulty hardware, or software conflicts.

Advanced recovery tools as well as professional computer repair may be necessary if DIY troubleshooting is unsuccessful. But in many cases, a few simple restarts, system scans, Safe Mode boots, or rolling back recent changes is all it takes to get your computer booting properly once again.
