Solution #3 – Make sure your computer isn’t overheating
An overheated laptop or desktop will attempt to prevent damage to critical hardware components by automatically shutting down. This is one of the main reasons why Windows 11 PCs get stuck in a reboot loop. If you notice that your desktop is emitting much more heat than usual, or if your laptop feels hot to the touch, you may have an overheating issue.
Your computer’s CPU and GPU generate the most heat, so it’s a good idea to monitor these hardware to see if they’re overheating. No additional software is required to monitor GPU temperature. some Temperature readings are built into Windows 11. Here’s how to check your hardware temperature in Windows 11.
- Open. task manager
- Click on the second tile. performance, on the left side of the screen

Unfortunately, the built-in temperature readings don’t read the CPU temperature, so you have to manually access the UEFI/BIOS to check the temperature without installing any additional software. However, there are many free-to-use apps developed by manufacturers to measure CPU temperature, such as Core Temp, HWMonitor, and Open Hardware Monitor.
When you open one of these monitoring tools, you can view your PC’s statistics such as CPU and GPU temperature and load. If your CPU or GPU is running too hot, try cleaning and dusting the components. For custom-built desktops, adding an exhaust fan to the case improves airflow and cooling. If your laptop continues to overheat, especially on older laptops, it may be a sign that it’s time to consider upgrading your machine.

A defective power supply can not only cause shutoffs and restart loops, but also blue screen of death errors. In severe cases, you may smell a burning odor or see smoke coming from the exhaust vent of your PC’s power supply. If you have a laptop with a PSU problem, you cannot send your computer to a repair shop or manufacturer for repair.
As a desktop PC owner, it’s a little easier assuming you have an off-the-shelf PC that can be easily modified. If you have a desktop, turn off and unplug your computer before entering the case to see if dust buildup is affecting your PSU. If your PSU fails, you will need to purchase and install a new PSU.
