My PC Powers Off During Startup; What Should I Do?


The most common cause of a computer shutting down in the middle of its startup process is a hardware failure. The problem’s resolution may vary depending on details like how far the computer has booted up, the last message the user saw, and so on.

1. Excessive heat

Second, Repairing Errors and Cleaning the Registry

Third, RAM might not have been set up correctly.

Fourth, double-check all electrical plugs and cables.

It’s a good idea to try out different random access memory devices on your machine.

Possibly Infected with a Very Ancient Virus




The overheating problem may cause your computer to shut down unexpectedly, either during normal use or during the startup process. This could happen if the CPU’s fans are clogged with dust and aren’t functioning properly.


First, power off your device.

2. Unlock the computer’s storage cabinet.

Take out the two ventilators. One fan is fastened to the top of your processor, while the other is hooked to the case of your central processing unit. Always exercise caution when working on the processor’s fan.

Use brushes to clean the blades of both fans. Clear the fans of dust.

Install the cooling fans, reassemble the central processing unit cabinet, and power on the computer when you’re done.


Repair Errors and Clean Up the Registry


Caused by errors in the Windows Registry, which prevent the computer from booting up properly. The main reasons of this issue are incorrect data and old information in the registry.


First, power up the device.

2. Boot into Safe Mode by pressing the F8 key.

3. Get the registry cleaner from the internet, set it up, and use it.

Fourth, select Registry Cleaner | Begin Scan.


It’s not simple to manually clean and fix the registry. It is advised that you utilize reliable registry cleaning software.


Possible Incorrect RAM Installation


Memory with random access is called “RAM.” If the RAM is not properly inserted in its slot on the motherboard, your computer will either power down immediately after startup or fail to boot at all.


Get rid of it and then put it back in the right way.


First, power off your device.

2. Unlock the computer’s storage cabinet.

Then, grasp the RAM by its edges while it is still outside of its anti-static wrapper.

4.decide which compartment you’d like to return it to. Either the same or a different slot will do.

Five, set up it correctly.


Verify all Power Sources and Data Connections


Verify the integrity of your CPU Cabinet by checking the Data Cables and Power Cords. For instance, the cables that supply power to your hard drive’s SMPS. Verify that the hard drive’s data cable is plugged into the computer’s motherboard.


Alternate Memory Modules on Your Device


The Blue Screen of Death (BSOD) is caused by faulty RAM, which can also result in a computer shutting down at startup. Even if you manage to get into the BIOS, your computer may suddenly shut down while your operating system is loading.


You should swap in some known-good RAM and see how it performs. If you need instructions on how to remove and reinstall RAM, check out the section on RAM that wasn’t installed correctly.


Possible Infection with a Very Ancient Virus


The computer frequently reboots itself in a random fashion due to old viruses. There has been a technological uptick. These days, rather than simply powering down, they reboot the machine. The most up-to-date security suites can swiftly identify and eliminate even the most ancient infections.


But if that does happen, you’ll need a rescue CD to get your entire system back up and running.


Step 1: Use a regular computer to download the rescue disk’s ISO file and then burn it to a blank DVD ROM.

Second, put in the DVD-ROM and reboot your computer.

3. Keep pressing F2 or Delete until the BIOS Setup Screen appears.

In this scenario:

a. DVD-ROM Is The Primary Boot Media

Disk Drive b) Secondary Boot Device

5. Put the settings to rest and reboot the computer.

Just hit any key when prompted, number 6.

Follow the on-screen prompts to disinfect your machine. 7. If you’re using a rescue disk, it’s best to boot into Graphical Mode rather than the DOS-only No GUI Mode.


Strongly Suggested


Keeping your computer in good operating order and speeding it up periodically is essential, even if the issue was caused by hardware components. Common causes include an abundance of unnecessary files and an inefficient or inaccurate registry. Many of them cannot be undone.


Preventative measures are preferable to curative ones. To that aim, I’ll suggest a few things you can do on the internet once a week to sharpen your skills.
