Sometimes, a computer randomly restarts without any warning or error message. This can happen when the computer is first turned on or after it has been running for a while.
But why does my computer randomly restart?
Well, a few things can cause a computer to restart randomly. It could be a problem with the hardware, such as a faulty power supply or overheating components. It could also be a software issue, such as a virus or corrupt file. Sometimes, random restarts can be caused by a combination of both hardware and software problems.
In this blog post, I’ll answer these questions and describe all the possible ways to fix them quickly. Stay tuned and learn what you need!
If your computer is configured to PC restart after a system failure automatically, you can disable this feature to prevent it from happening.
This can be useful if you want to troubleshoot the cause of the crash without having to restart your computer constantly. To disable it, follow the steps below.
If your computer randomly restarts, it could be due to various reasons. One potential reason is the power options in Windows. You can change the power options to see if that fixes the problem.
To change the power options:
If your computer is randomly restarting, it could be a hardware issue. To check for hardware issues, you can:
If you suspect that a hardware issue is causing your computer to restart randomly, you can try:
It’s never done this before, and I last noticed my CPU temperature was high. Is there a way to check my computer’s temperature and fix the issue?
PC temperature can be checked in a few different ways. You can use a program like Core Temp or Speccy or check the temperatures in your BIOS. If your CPU temperature is high, there are a few things you can do to fix the issue.
Check for airflow blockage: Make sure that all your case fans are working and that there is no dust blocking airflow to your CPU cooler.
Ensure your CPU cooler is properly seated: Sometimes, the CPU cooler can become loose. You’ll need to remove and reattach it to ensure it is seated properly.
Check for thermal paste buildup: If there is too much thermal paste on your CPU, it can cause overheating. You’ll need to clean the old thermal paste and apply a new layer.
Use a better CPU cooler: If you’re using a stock CPU cooler, it might not be adequate for your needs. You may need to invest in a better aftermarket CPU cooler.
One of the most common causes of random restarts is an outdated BIOS. The BIOS (Basic Input/Output System) is a chip on your computer’s motherboard that stores essential information about your system.
If you’re experiencing random restarts, it’s a good idea to check if your BIOS is up to date. Here’s how:
The first step is to check what version of BIOS you have. You can typically do this by checking the documentation that came with your motherboard or by looking for a sticker on the motherboard itself.
Once you know what BIOS version you have, you can check if there’s an update available. You can do this by visiting the website of your motherboard’s manufacturer.
If there’s an update available, follow the instructions on the website to update your BIOS. This process is usually fairly straightforward, but it’s essential to follow the instructions carefully to avoid any problems.
After you’ve updated your BIOS, it’s a good idea to check for any other issues causing your random restarts. This includes things like drivers, software, and hardware.
If you’re still experiencing random restarts after following these steps, it’s a good idea to contact a computer professional for further assistance.
I will explain how to do this in two different ways. The first way is to open your computer’s case and look at the PSU. The second way is to use a program like HWMonitor.
If you open your computer’s case and look at the PSU, you should look for any obvious signs of damage.
If you see any burns or charred components, that is a sign that the PSU is failing and needs to be replaced. You should also check to see if any cables are loose or damaged.
When you see bare wires, that is another sign that the PSU is failing and needs to be replaced.
If you use a program like HWMonitor, you can check the PSU’s voltage outputting. If any voltages are outside the normal range, that is a sign that the PSU is failing and needs to be replaced.
If you suspect your PSU is failing, you should replace it as soon as possible to avoid damaging your other components.
The vital thing you should do when your computer randomly restarts is to check your RAM. If you have a bad or failing RAM chip, it can cause your computer to restart randomly.
To check your RAM, you can use a program like Memtest86. You may find that you have a bad or failing RAM chip; you should replace it as soon as possible.
When you have multiple Random Access Memory chips, you should also check them all to see if any of them are wrong. If you replace a bad RAM chip, it can help to fix your computer’s randomly restarting problem.
A random computer restart could be a sign of a bigger problem. One way to try and troubleshoot the issue is to start your computer in Safe Mode.
If you can identify the problem, you can try fixing it and restart your computer in Normal Mode.
If you have installed any new programs recently, they may be causing your computer to restart randomly. Try uninstalling any new programs and see if that fixes the problem.
You may be unsure which program is causing the problem; you can try uninstalling all the new programs you have installed until the problem is fixed.
When you still can’t figure out which program is causing the problem, you can try resetting your computer to an earlier time when it was working correctly. This will undo any changes to your computer, including any new programs installed.
Random restarts can be caused by various things, including hardware issues, software conflicts, and driver problems. This can help rule out software conflicts as the cause of your random restart issue.
To do a clean boot, follow these steps:
A system restores your computer to a previous point in time, which can be helpful if your computer is randomly restarting.
To perform a system restore:
A system won’t affect your personal files but will remove any programs you installed after the restore point was created.
If your computer has unexpected Restart, it could be a problem with your graphics driver.
When your computer randomly restarts, it may be due to a virus or malware. Running a virus scan can help you determine if this is the case.
There are a few different ways to run a virus scan. You can use a free online scanner, download and install an antivirus program, or use a built-in scanner if you have Windows 10.
To run a virus scan using a free online scanner, go to the website of an antivirus provider and use their online scanner. Some popular online scanners include VirusTotal and MalwareBytes.
To download and install an antivirus program, go to the website of an antivirus provider and follow their instructions. Some popular antivirus programs include Norton, McAfee, and Avast.
To use a built-in scanner in Windows 10, go to the Start menu and search for “Windows Defender.” Then, click “Scan now” to begin the scan.
When you experience random restarts on your computer, it could be caused by a driver issue. To help narrow down the cause, you can run the Driver Verifier tool.
This tool checks for corrupt or faulty drivers and can help fix them. To run Driver Verifier:
If you experience any crashes while Driver Verifier is running, there is a problem with one of your drivers.
You can use the crash dumps to help figure out which driver is causing the problem. Once you’ve identified the problematic driver, you can try updating or reinstalling it.
Fast startup is a Windows 10 that helps your PC start up faster after shutdown. However, the fast startup can sometimes cause random restarts on your PC.
To disable fast startup, follow these steps:
1) Go to Start > Settings > Power & Sleep
2) Under “Related Settings,” click the Additional power settings link.
3) In the Power Options window, click Choose what the power buttons do.
4) Click Change settings that are currently unavailable.
5) Under Shutdown settings, uncheck the Turn on fast startup (recommended) option.
6) Click Save changes.
After you disable fast startup, your PC will take a bit longer to start up, but it should no longer randomly restart.
Why does my PC randomly restart without warning?
The blaster virus, for example, is programmed to restart your computer without prior notice.
Viruses usually cause the computer to restart every 5, 10, 15, or 30 minutes after it has started, depending on the infection.
Can the power supply cause random restarts?
Overheating of the CPU/GPU and the subsequent shutdown of the system to avoid further damage are the two most common causes of unexpected reboots and shutdowns.
There is a problem with the PSU’s ability to send adequate power to the GPU or to maintain a stable voltage for the PC’s operation.
Can RAM cause random reboots?
When you’re in the midst of anything, your computer suddenly shuts down or freezes. As soon as you open your desktop, it may shut down and restart instantly.
Possibly insufficient RAM is at blame. Before the system restarts, a blue screen with white lettering flashes on and off in rapid succession.
Will a failing hard drive cause random reboots?
Computer failures happen in a variety of shapes and sizes. Sudden reboots are a warning that the hard disk may be failing.
Your computer’s screen goes blue, freezes, and may even demand a reboot, which is what the blue screen of death is.
A computer crash while attempting to access data is a significant indicator of a hard disk failure.
What is the lifespan of a CPU?
The CPU is one of the most dependable sections of a computer. The CPU is unlikely to die unless one or more of the system’s primary components, such as the CPU fan, power supply, or hard drive, also fails.
When a CPU is overworked and overheated, this might shorten its lifetime. The lifespan of a CPU should be at least seven to ten years.
Is it okay to turn off the computer overnight?
According to Nichols and Meister, even if you often use your laptop in sleep mode, it’s a good idea to shut it down entirely once a week.
The longer you use your computer, the more background processes, such as cached attachments and ad blockers, will be active on your system.
Which is better, sleep or shutdown?
Booting from sleep is substantially quicker than booting from a shutdown, and it may almost seem instantaneous on faster computers.
Laptops and desktop computers both use more power when you sleep. As long as the machine’s power supply remains steady, it will preserve all of its memories while it sleeps.
There are a few things that could be causing your computer to restart while playing a game. It could be an issue with the game, your computer’s settings, or a problem with your hardware.
If you’re having this issue with a specific game, try updating it or reinstalling it. You can also try running the game in compatibility mode.
When your computer’s settings are causing the issue, you may need to adjust your power settings or disable features like hibernation.
Finally, if the problem is with your hardware, it’s possible that a driver needs to be updated or that there’s a hardware conflict. You can try updating your drivers or running a diagnostic tool to check for hardware problems.
