PC turning off randomly

PC turning off randomly

If PC turning off randomly, here’s what you’re doing. There are a few key things to check out:

1. Heat

2. Power

3. Defective Hardware

4. Problem with Software or Operating System

We have four possible reasons for PC turning off randomly.

To effectively resolve accidental exclusions, you must look at each of these main causes. The most common causes are heat and strength. If your computer heats up too much, the BIOS or CPU will shut down to save from overheating. If your power supply is not working correctly, it will not deliver the exact or stable required voltage. Again, the BIOS or CPU will shut down.

Faulty hardware and software are rarer. If your computer shuts down completely, this is more likely hardware. If your computer restarts, it could be software. As the question was about shutting down and not restarting, That’s all I’m going to deal with.

As mentioned, it is impossible to offer details in the network instruction. Instead, I’ll show you where to look to isolate the cause.


PC turning off randomly, first possible reason. Heat is the enemy of electronics and will cause computers to shut down to save overheating and damage to hardware. Download and install an HVMonitor or alternative that indicates voltage and temperature. Keep it running where you can see it, and monitor your system temperature while you’re using your computer.

For safe working temperatures for processors, see this page . It is very useful and displays a wide range of processor types. Browse to this Safe Times page for Nvidia GPU . I can’t find the AMD equivalent page, but I’m guessing the same maximum temperature of 100C. This is the maximum tolerable temperature, not one that the GPU should be working on when using games or intensive programs.

If you’re overeating, switching to watches is the first thing you should do.

If your computer is hot, turn it off and remove all dust from the inside of the case. Make sure all the housing fans are working and they’re sucking the air in from the front and throwing it up or in the back. Consider adding more fans or fixing cables for better air flow if the problem is.


PC turning off randomly, another possible reason. Computers are very sensitive to fluctuations in power. Even small voltage differences can cause the motherboard or processor to shut down to protect themselves. There are several things you can check to confirm stable strength.

Use the HVMonitor to make sure the voltage doesn’t fluctuate too much. Use the UPS or the power bar that controls voltage and provides voltage protection. Try using a different power supply if yours is old.
It’s useful to have backup power anyway if you depend on your computer. Buy quality from a recognized brand, not cheap imports. 

If you don’t have backup power, see if you can borrow it for a few hours to test it. There really is no other way to fix the power problem without it.

I always suggest that you use too voltage protective tape for your computer. Not only does it protect him from these voltage hits, but he cleans the voltage from the net. Even in the newest cities, network voltage varies quite widely. Typically, computer power can be carried, but refining that voltage using the power bar reduces the stress on that power supply.

Defective Hardware

Detection of faulty hardware is notorious, but rarely PC turning off randomly. Unless something apparently smokes, melts or burns or is otherwise damaged, finding the culprit is the process of removal.

How come someone doesn’t know
Restore the BIOS to its default values and return to your clocks if you override. Remove one PCI card or RAM stick each and monitor. Replace and try another if your computer shuts down. If you are using external audio and / or graphics and have built-in technology, temporarily switch to built-in audio or graphics and test again. This setup is in the BIOS. Remove the video or sound card before turning it back on. Switch RAM slots and sticks and monitor. For detail each separately.

If your computer stops shutting down randomly, see the last change you made. Note where your hardware is and undo the last change. It’s likely that your computer will shut down again. Repeat the last substitution to make sure it’s not a one-time one-off. If your computer remains stable, instability is what you moved or removed. Replace it as needed.

Problem with Software or Operating System

Rarely would the software or your FA cause your PC turning off randomly. Typically, a software glitch would trigger a reboot, not a shutdown. However, if you use Windows, all bets are off.

Follow all the top steps for heating, power, and hardware. If it doesn’t appear to be any of that and you’re using Windows, restart the system to safe mode. Play a movie or run a simple browser game to run and monitor it. If your computer shuts down, the problem is at the windows core. If your computer stays stable, it could be something else.

Upgrade Windows and manually update all major drivers. Check the BIOS version and update it if necessary. Temporarily remove any surveillance software or fan management software that you may be using.
