How to Fix PC Infinite Boot Loop After Installing New PSU?

Is your computer system stuck on an infinite boot loop after installing a new PSU or any other hardware? Here are 8 easy fixes you can try.

Building a gaming PC can keep you stuck with many problems; either your PC does not boot at all, or it’s stuck in an infinite loop. The constant cycle of crashing and starting up again can get frustrating, especially if you’re doing something important. Fortunately, there is an easy fix for it.

To fix the PC infinite boot loop, try to restart your computer system in safe mode. You can use a bootable USB drive with a Windows file and access the safe mode via the boot menu. If that doesn’t work, try resetting the BIOS settings to system default to fix the boot sequence.

There could be many reasons why your system gets stuck into a boot loop, but most commonly, it happens due to software or hardware malfunction. In this article, we will guide you on how to fix the PC infinite boot loop after installing a new PSU or hardware. We will also discuss some major reasons a PC infinite loop occurs due to hardware and software concerns.

Why Does Infinite Loop Occur on a Computer System? 5 Major Reasons

Here we have discussed a few reasons why your PC boot loops even after new power supply may occur due to software and hardware changes.

1. Faulty Hardware Components

If you have recently built your computer system and your PC is running an infinite boot loop, there are significant chances that it could’ve happened due to a hardware issue.

Perhaps you may have installed the processor incorrectly, or the RAM is not installed properly. It’s also important to check the power supply if you have recently changed or installed a new one in your system.

2. Overheating

PC Overheating is another common reason your computer system may run into an infinite loop sequence or experience a black screen of death on Windows. Your computer may automatically restart if the CPU or GPU gets too hot, especially via playing CPU-intensive games.

3. Corrupt Master Boot Record

The Master Boot Record guides the computer system to run with the boot sequence of the OS installed. If, by any chance, the Master Boot Record of your computer system gets corrupted, your PC can get into an infinite loop due to not getting proper instructions for starting up. In most cases, this can happen when you accidentally overwrite new data on the MBR or due to malware in the system.

4. Newly Installed Program Interference

If you have recently installed a new program, then it might be a chance that OS is prioritizing running that new task over anything else on your computer system. It is quite common when you install an incompatible driver or if that program is installed in a different hardware than the operating system.

5. Corrupt Drivers

A computer system solely relies on its hardware to make things like GPU, RAM, and everything else compatible with the software system. Therefore, if some wrong drivers are installed on your computer system or are corrupted due to malware, your PC can enter into an infinite loop.

Fixing the PC Infinite Boot Loop With 8 Easy Methods

Here are some potential fixes that you can try to get your PC out of the infinite boot loop sequence. We have also discussed certain fixes for certain types of boot loops that may occur at different stages.

Fix #1: Run Automatic Repair

The best way to fix a problem is by applying an automated troubleshooting fix, and it is pretty easy to do so if you’re running a Windows operating system. You can perform Automatic Repair on Windows by following these steps.

  1. To power off the system from the loop, hold the power button for 5 seconds until the PC shuts down.
  2. Again, press the power button and immediately press the F8 key until the Advance Boot Options appear.

Fix #6: Check Your Power Supply

Now that we have applied and discussed the software issues let’s proceed to discuss some potential hardware issues that could cause the infinite boot loop. Therefore, you can run a built-in self-test on your power supply to see if it shows the green light, meaning it works properly.

Pressing Button to Check if Power Supply Works Properly

You can perform the built-in self-test by simply pressing the button on your PSU while the power cable is plugged in and switching ON from the wall socket. In case there is no button on your power supply unit, plug in the power cable while it’s switched ON from the wall socket to see if the light on the power supply turns green.

Fix #7: Change RAM or Hard Disk

Your computer system’s memory and storage components can be the sole reason your PC could face boot issues. A faulty RAM or memory stick placed in different slots can cause restarting loop or boot issues, especially with Windows 10. Such an issue can happen if you have recently installed RAM.

Reinstalling RAM in a different slot

As for the storage drive, such an issue can occur due to a possible issue or the hard drive being corrupt due to malicious software. In this case, you can try unplugging the hardware if you have more than one to see if the loop stops. You can also try switching to the hard drive that contains Windows only to see if that works.

Fix #8: Reinstall Operating System

Installing a new operating system is the last option to fix the Windows loop issue. Your operating system may be corrupt, which causes the boot loop issues. Therefore, you can implement the following steps to reinstall Windows safely.

  1. Boot your PC in Safe Mode with networking.
  2. Back up all your necessary files.
  3. Download the latest version of Windows files from Microsoft Website and write them on a bootable USB.

4. Restart your computer and go to the Boot menu to install Windows from bootable media.
