Does your Windows PC shut down or restart without warning? There are several potential causes behind that. For example, it could be a software/hardware conflict, overheating, or hard drive error. This troubleshooting guide will outline multiple solutions to fix auto-shutdowns and restarts in Windows 10/11.
If your computer shuts down constantly, you must boot your computer in Safe Mode or use the system recovery options in WinRE to work on the fixes below.
1. Check the Task Scheduler
If your computer shuts down automatically but only at a specific time of the day, that’s probably due to a scheduled task that you or a third-party program created. To check:
- Buksan ang Start menu, type Gawain Scheduler, at pindutin ang Magpasok.
- Review your computer’s list of scheduled tasks under Gawain Scheduler (Thư viện).
- Right-click any tasks that force your PC to shut down or restart and select Huwag paganahin ang.
2. Huwag paganahin ang Mabilis na Startup
Mabilis na Pagsisimula is a Windows power management feature that hibernates the kernel (the operating system’s core) to speed up your PC during a cold start. However, it can destabilize the system.
Upang hindi paganahin ang Mabilis na Startup:
- Buksan ang Windows Control Panel at piliin ang Hardware at Sound > Mga Pagpipilian sa Power > Piliin kung ano ang mga power button do.
- piliin Baguhin ang mga setting that are currently unavailable.
- Alisan ng check ang kahon sa tabi I-on ang mabilis na startup (inirerekomenda).
- piliin I-save ang mga pagbabago.
- Buksan ang Start menu at piliin ang kapangyarihan > Patayin.
- I-reboot ang iyong computer.
3. Update Windows to Its Latest Version
Specific versions of Windows contain severe bugs and issues that cause significant problems with particular hardware and software configurations. Install the latest operating system updates to fix them.
- Buksan ang Start menu at piliin ang Setting.
- piliin Windows Update.
- piliin Suriin ang mga update. If there’s a new update, select Mag-download at mag-install.
4. Update Your Computer’s Drivers
Hindi na ginagamit hardware device drivers are a common problem behind a computer that shuts down or restarts randomly. Use a utility sa pag-update ng driver gaya ng Driver Booster to update your computer’s drivers.
Additionally, use Windows Update to install Microsoft-verified hardware drivers and updates. To do that:
- Buksan ang Start menu at piliin ang Setting.
- piliin Windows Updatee.
- Pumunta sa Advanced na mga pagpipilian > Opsyonal na pag-update and install all pending driver updates.
5. Roll Back Driver
Rarely, new driver updates can introduce issues and break down the system. Microsoft knows that, which is why you have the option to roll them back.
For example, if the problem occurred after updating your graphics card driver:
- Mag-right-click ang Start menu at piliin ang Device Manager.
- Expand the driver category—Mga adapter ng display.
- Right-click the graphics card driver and select Mga Katangian.
- Lumipat sa Drayber Tab.
- piliin Roll Back Driver.
6. Run the SFC and DISM Tools
Windows comes with two command-line tools—System File Checker and DISM—that can scan and fix system file corruption.
Open an elevated Command Prompt console—type cmd into the Start menu and select Buksan bilang administrator—and run the following commands one after the other:
sfc / scannow
DISM.EXE /Online /Cleanup-Image /Restorehealth
SFC and DISM scans take a long time to complete. If the progress percentage indicator gets stuck, do not do anything; it should resume eventually.
7. Patakbuhin ang CHKDSK
Susunod, patakbuhin ang CHKDSK (Check Disk) utility to fix HDD/SSD errors in the system partition. Again, open an elevated Command Prompt console and run the following command:
chkdsk c: / r
CHKDSK only runs at computer startup, so press Y to schedule the scan the next time you reboot your computer.
8. Troubleshoot BSOD Errors
If your computer crashes and restarts into a Blue Screen of Death (BSOD) screen, it will continue to repeat that until you diagnose and troubleshoot it with the appropriate fixes.
Start by noting down the stop code related to the BSOD error—e.g., Pamamahala ng kaisipan, Kernel_Security_Check_Failure, Driver_Overran_Stack_Buffer, etc. Then, refer to our complete BSOD troubleshooting guide to learn what you must do next.
9. Tingnan kung may Nakakahamak na Software
Malicious software and potentially unwanted programs (or PUPs) can wreak havoc on the operating system and trigger unexpected shutdowns and restarts.
If the problem persists, you must scan your computer for potential malware. Windows Defender isn’t likely to do any good pagkatapos a severe infection, so your best option is to rely on a third-party virus removal utility.
For example, the free versions of Bitdefender Antivirus at Malwarebytes are extremely effective at detecting malware. Download either one, run a quick scan, and then follow up with a full scan.
10. Magbigay ng Sapat na Bentilasyon
Inadequate ventilation leads to overheating, forcing your computer to shut down to cool itself. For example, if you use a laptop, avoid using it on soft surfaces—cushions, bed covers, etc.—that could plug up its ventilation holes. Also, check and clean the CPU or laptop casing to ensure nothing is blocking the airflow.
11. Magsagawa ng isang System Restore
If the shutdowns and restarts persist, roll back Windows to a time when it did not shut down or restart automatically. Assuming that Ibalik ang System is active on your computer, you must:
- pindutin Windows + R upang buksan ang Run. Pagkatapos, i-type rstrui sa Pagbubukas patlang at piliin OK.
- Pick a restore point and select I-scan para sa mga apektadong programa to identify the changes to expect if you decide to go ahead.
- piliin susunod and follow the onscreen instructions to revert your computer to the restore point.
12. Magpatakbo ng Memory Test
Faulty RAM (random access memory) modules are another reason for random shutdowns and restarts. Windows comes with a built-in Windows Memory Diagnostic tool you can run to scan for bad memory.
- uri Diagnostic ng memorya ng Windows into the Start menu and select Pagbubukas.
- piliin I-restart ngayon at suriin kung may mga problema (inirerekumenda).
- Wait until Windows Memory Diagnostic reboots your computer and tests it for memory problems.
For comprehensive step-by-step instructions and alternative methods, check our guide to testing a Windows PC for bad memory.
13. Reset/Update the BIOS or UEFI
Outdated or incorrectly configured motherboard firmware—the BIOS or UEFI—creates stability issues. Check if the BIOS needs an update or revert it to its default settings.
14. Factory-Reset or Reinstall Windows
If none of the fixes above help, you must reset Windows to its default settings. I-back up ang iyong PC, at pagkatapos ay:
- Buksan ang app na Mga Setting at piliin Sistema > Pagbawi.
- piliin I-reset ang PC.
- piliin Panatilihin ang aking mga file (if you want to keep personal files intact) or Alisin ang lahat.
If that fails, you must remove and reinstall Windows from scratch.
15. Kumuha ng Tulong sa Propesyonal
If the problem persists and your computer continues to shut down and restart automatically, you might be dealing with a faulty hardware component or a defective power supply unit. Visit your local PC repair shop and let a technician take a look at it.
