Common Computer Problems – Computer Keeps Restarting

It can be really frustrating when your computer keeps restarting on its own.

There are lots of factors that can contribute to this problem and it is mostly not easy to identify which one. Such    factors include software issues, hardware malfunction, computer virus, overheating, and corrupt windows installation.

If your computer automatically restarts without a warning and you have no idea what to do about it, you can try the following methods to fix it.

If your computer enters the Windows Operating System before restarting, then you will need to first of all disable the ‘Automatically restart’ feature by following the steps below:

  • Boot the computer into ‘Safe Mode’.
  • While in Safe Mode, open the ‘Run’ app by pressing the Windows logo key ( Windows Logo Key ) and ‘R’ at the same time on the keyboard.
  • Type sysdm.cpl and click OK
  • Click the Advanced tab, and click Settings in the Startup and Recovery section.
  • Uncheck Automatically restart.
  • Click OK to save.

Let’s look at some other problems that may keep restarting your computer. You will also find possible solutions to these problems in the post so keep reading.

Hardware Malfunction
Computer Hardware

One of the most common reasons that lead to automatic rebooting is hardware malfunction. You will need to disconnect any recently added hardware device to check whether it is causing the computer to restart. You must also ensure that all cables and power sources are properly connected to the computer. Sometimes a loose connection can make the computer reboot over and over.

You can also check if there is no hardware conflict in the computer by following the path below:

Start  Arrow  Search    Arrow Device Manager   Arrow Press Enter.

You can alternatively go to the Device Manager through the Control Panel.

The “Device Manager” will list all the hardware attached to the computer and indicate the ones which are not properly connected by having one of the following against its name:

  • A yellow exclamation mark or ‘Other Devices’
  • A red ‘X’ symbol
  • A Down arrow
Device Manager
  • Yellow Exclamation Mark/Other Devices : A yellow exclamation mark indicates a device which is not compatible with other hardware devices, or its drivers have not been installed. To rectify this, delete all devices with yellow exclamation mark against their name, or which fall under ‘Other Devices’. Then restart the computer and check if the Operating System (OS) has detected them. If the problem persists then you will need to download the latest drivers for those devices.
  • A Red ‘X’ Symbol : A red ‘X’ indicates that either the device has been removed or the OS is unable to detect it. To rectify, ‘enable’ the device from the ‘Device Manager’ tool and restart the computer to check if the OS has now been able to detect the device. Otherwise, you will need to download the latest drivers for the device.
  • Down Arrow : Devices with a down arrow against their name is an indication that the devices have been disabled. They can be easily enabled through the ‘Device Manager’ tool.

RAM (Random Access Memory)

The RAM or memory can be of the issues causing the computer to automatically restart. You need to take a look at your RAM itself and the slot in which it is inserted. There can be a problem with the RAM itself, the slot, or could be heavy dust. Sometimes the restart happens with a beep sound. If it does, it is very likely the RAM is having issues.

To solve this, you need to go inside the system unit and remove the RAM from the slot and clean both RAM and slot. Try and see if the PC is restarting again or not. If it is still the same, try inserting the RAM into another slot and check. If it persists, then you will have to run a scan on the memory.

Windows OS is equipped with ‘Windows Memory Diagnostics’, which runs a memory test on the computer. You can open this tool by following the path below:

Start   →  Control Panel   →   Administrative Tools   →   Memory Diagnostics Tool.

If it turns out the RAM is faulty it will have to be replaced. Otherwise, the motherboard might also be suspect and a new one will have to be installed by a technician.

 Computer Virus
Virus Alert

Some nasty viruses which infect the computer can make it restart automatically.  If your PC is restarting because of viruses, use your Antivirus’ boot time scan feature, and turn it on. So, that when next time your PC gets rebooted, the boot time scanning will be started, and the viruses will be deleted before they load.

Alternatively, you can boot your Windows in safe mode in which viruses or malware and even most of the third party drivers don’t get loaded. Once PC is in safe mode, do a complete scan of your PC and remove viruses.

If a virus makes the computer restarts before the OS is loaded, the computer might tell you there is no operating system found. At this point you do not need a virus protection as you cannot enter the windows operating system. In some of these cases, if it is impossible to get the viruses removed, formatting the hard drive is the only option, but then only you should choose this option. If it is a virus that attacked the computer, the fan will continue running without anything on the screen. If the fan is still running, you must reinstall the windows operating system.

CPU Overheating

Sometimes due to some issues, your computer’s processor may get overheated abnormally, and that can be a big reason for your computer to keep rebooting. This has been the most popular reason for getting a PC restarted randomly.

If the CPU is not getting enough air flow mostly due to dust cover, when it goes into the operating system the PC temperature will go up high. This will cause an automatic shutdown to prevent the computer from catching fire, that’s why computers need fans.

Get the dust out from the CPU and especially from the processor’s fan and areas around the processor. Make sure the fan attached just above the processor is running, and check if the heat sinks are seated correctly or not. Clean all dust off of the computer case and once you are done, close your computer and start it, it should load up.
