Your computer can randomly restart due to multiple causes. Let me explain them one by one. The first reason (and most common) is overheating. Your computer has inbuilt mechanisms to deal with the processor heat. However, if the device’s heat exceeds the safe level, it will automatically restart. Let us know ‘The Computer Randomly Restarts No Blue Screen’.
The Computer Randomly Restarts No Blue Screen
There are several other software and hardware-related issues that can cause your computer to randomly restart. These include power issues, software and driver errors, etc. Also, the Windows Update process. If your computer faces an error with a Windows update, it will reboot. An insufficient power supply will cause your computer restarts randomly.
Reasons and Solutions
Computers have many software and hardware-related issues. One of the most common computer issues is the unexpected automatic restarting of a computer with no blue screen appearing. Once faced with a situation where your computer reboots automatically without providing any warning, you may end up losing every unsaved work.
Reasons
- Software and Driver Error. When your computer restarts randomly and no blue screen appears, it may mean the software or driver installed is not compatible with your Windows Operating system.
- Overheating: Your computer has inbuilt mechanisms to deal with the processor heat. However, if the device’s heat exceeds the safe level, it will automatically restart.
- Sometimes a computer can randomly restart due to corrupted RAM.
- Loose power cable, loose SATA cable, overheated processor, failing power supply
Solution
You can solve the computer randomly restating and no blue screen issue by uninstalling the software or driver recently installed if you suspect it is the reason for the random restarts.
- Perform a Windows system restore. You can restore your windows OS to an earlier state and point before an update or a change e.g., installing new software or driver that causes the computer to randomly restart.
- Check on dirty fans and dust accumulated on the hardware, and any reasons that can cause overheating hence random restarts.
- Replace the RAM. Sometimes a computer can randomly restart due to corrupted RAM. Replacing the RAM modules can ascertain if they are the culprits, and if they are, replacing them can solve the random restarts issue.
- You should check the exact reason for your computer problem and fix it to prevent random rebooting.
- Check your event viewer for the last event before any restart it may show probably a hint of an issue.
- Boot to safe mode/ boot to recovery via a disk and run Chkdisk /f / r check disk with force and repair
- Download the Bitdefender rescue disk and scan your pc thoroughly for any viruses that may be on the computer
- Run applications like cc cleaner/registry cleaner
- Change the thermal paste off the computer
- If it persists dismantle and reassemble the machine or take it to a computer repair shop.
- If the restart is a “hard” shutdown, check the power supply and also check whether there are fluctuations in the wall socket voltage which a UPS might solve.
- If the restart is just a standard shutdown/reboot with the screen that says “logging off” or “shutting down,” then this is software related. Also, make sure you have all current Windows updates.
- If it’s a hardware problem then most issues for random restart come from the RAM, HDD (data redundancy-check), or the CPU struggling with many loads.
- If your CPU is Intel based after some thermal increase the CPU shuts down to avoid melting.
- If the computer makes a BEEP when it resets then it may be that the RAM is the issue here. You can open the computer and clean the dust off.
- Also a thermic repaste of the CPU can help.
Procedure For Diagnosing What Is Causing Your Computer to Randomly Restart, And Procedure on How to Fix?
This could be due to overheating, after a certain temperature your computer will hardware reset, which means it will completely turn off without showing any warning, shutdown loading thing, or anything. Perhaps it will restart afterwards, but this is caused by overheating very often, so if you think your temperatures are unusually high then open your pc up and clean the dust in the vents.
Generally, computer rebooting randomly can be caused by many reasons, for example, the misbehaving automatically restarting feature, overheating or a faulty power supply, faulty RAM, a virus or malware issue, driver problems, Windows update, etc.
Procedure:
- Open it up and take a look. Dust? Shorts (little black burn marks)? Loose connectors? Frayed wires? Working fan(s)? Correct these.
- Carefully pull and reconnect all wires and connectors. Do the same for all cards and memory sticks.
- Power back up and see what happens. If it’s still there:
- Pull all but one memory card and try again.
- Swap memory cards one at a time and try again.
- Remove all (unneeded) add-on cards and try again.
- Download memtest86, burn it to a CD/DVD and boot to it. Run it.
- Power back up each time and see what happens. If it’s still there:
- Pull the HDD/SSD and copy off all of the data. Get the recovery media, re-install the HDD/SSD, and Reload the OS from scratch.
Reasons For the Computer Randomly Restarting During Certain Tasks Such as Playing Video Games
- It sounds like an overheating issue. If you put it on something soft and/or fuzzy, like your bed, you may be blocking airflow. Most laptops draw in air from the bottom and blow it out through the back, so anything that stops it from drawing in the air can make it overheat.
- The easiest way is to take pc apart, clean it, apply a new thermal paste to the CPU and if you can GPU, check all the leads, and check the fan’s work. Check all connections. If all that fails try Malwarebytes free and avg free, if a virus is found do a fresh install of windows and stay clear of certain sites. Look in the device manager for more info.
- It also is a symptom of a hardware problem. Chances are there is a defective component somewhere in your laptop. It’s typically an overheating problem, which is not uncommon in the cramped confines of a laptop. That might mean the fans or venting system of your laptop aren’t working, or the vents are dusty and there is little airflow.
- When you put the system under load, like when you are working on something or playing games, the processors work harder and produce more heat, and the damaged ventilation can’t keep up, and this forces the laptop to shut down or restart.
- More seriously, there may be damage to your CPU processor, memory, or some other component, and it causes a shutdown and/or restart when the system is put under stress.
- Unfortunately, these kinds of problems are all difficult to fix by yourself. Your best bet is to send the laptop in for repairs at a qualified technician, or for warranty at an official distributor.
- Can a loose power switch connector cause random restarts in a desktop computer? A defective power switch (on your computer, on the power strip your computer is plugged into, or anywhere else downstream from your computer) can cause random restarts in a desktop computer. So can issues with your computer operating system, especially if you’ve picked up a computer “virus” (a term that can cover a lot of possibilities).
That said, figuring out where the problem involves debugging skills you may not have. If you think it’s a power strip, plug it directly into the wall or get a new one (the least expensive possible solution). If you think it’s the power company add an uninterruptable power supply. If those things don’t resolve the problem and you feel comfortable digging deeper yourself, you can test your computer’s internal power supply and do virus checking (probably in the reverse order). If you don’t feel comfortable doing those things, take it to a computer repair professional and pay them to figure it out.
Conclusion
The things that could cause a computer to randomly restart and no blue screen to appear are extremely numerous, and so it would be impossible to diagnose the issue without any more information like what the computer model and specs are, the task you were performing etc. It could be a hardware problem (overheating CPU, bad RAM card, failing power supply, faulty switches in the case, etc.), an act of nature (power surges, little bugs crawling around on the motherboard, etc.), a software problem (badly coded software, corrupted files, malware, etc.), or accidentally kicking the power switch or the “test” button on the surge protector, bumping the “reset” button on the case, etc.
Frequently Asked Questions
Question 1: The Computer Turns Itself on And Off or Restarts on Its Own. What Will I Do?
Clean it, the fans and heat sinks get covered in dust and smokers. Computers get even more of a coating for the dust to stick to. A vacuum cleaner and brushwork are OK and dried compressed air with caution work well.
Question 2: Why Do Computers Turn Off Randomly and Then Restart?
The most common reason for random rebooting is a fault in the power supply. Also, this behaviour may occur on some laptops when the clock (CMOS) battery starts to fail
