My computer keeps rebooting itself.

A few evenings ago I was working on my computer (emachine) with no problems. The next morning it was frozen with on 'countdown' screen to reboot. I had to hard boot to get it to do anything. When it starts booting, the E logo comes up with my options to go to bios etc.... then it goes to the countdown screen. Whether I chose to boot normally or using last good config, it would just repeat the process of going to E logo screen. I got frustrated and turned it off for most of the day. When I turned it back on, it did the same thing, but this time when I chose last good config it actually start booting up. There was a microsoft error report, so I sent it. I tried to go download a critical windows update, but at approx 75% rebooted itself. This started the cycle over, however I was having much better luck at least getting it to boot all the way at least a couple of times, so that I could back up some recent files. I tried to restore, but it never seems to get to complete either. Essentially, at this point, I can get it to boot up, but if anything is running it won't take it long to start rebooting itself. Sitting idle it takes it longer to start rebooting. Please help!

Re: My computer keeps rebooting itself.

After doing what sandrew mentions in the previous post, and still getting the same problem, try resetting the BIOS (there should be a small jumper with three positions on it and a cap on two of them, close to the CMOS battery. you have to move it to the position that's open. If it is on position 1-2 , move it to position 2-3 for a few seconds and then back).
if you post your exact model I can probably tell you where the reset jumper is.
You can also try removing the memory from it's socket and putting it back again

Re: My computer keeps rebooting itself.

First check the cmos (3V disc shape)battery on your motherboard is ot flat, as this causes reboot loops. Also check that the processor fan is free of dust and so you can count out overheating.

My emachine will work great for an hour or so and then it automatically reboots itself

Check the event viewer to see if its spitting out a Critical error or warning. This might help you further troubleshoot why it keeps rebooting.

Computer comes on and is fine for a while then just cuts off,then turn it back on then its fine for a while then cuts back off.


To start with, you should check all your hardware. A loose connection somewhere or a faulty piece of hardware could be the reason, the computer keeps rebooting itself. In case your RAM stick is not fitted properly, or is corrupt, the computer displays an error message on the screen and keeps rebooting itself. The same problem occurs with a hard disk. You can use 'Memtest86' to run a hard drive check.

You may at times come across an error message on your screen, like a system failure error, before rebooting by itself. There is a particular solution to this type of problem. You should first go to the My Computer icon and right click on it. Select properties, and a window will appear on your screen. Click Advanced tab → Start Up and Recovery → Settings. After clicking the settings option, you will have to uncheck the box next to Automatically Restart. Click OK twice. This will prevent the computer from rebooting itself and you can redress the issue.

A different way to tackle the problem of 'computer keeps rebooting itself', would be to restart your computer in the Safe Mode. Allow the computer to boot fully and let your windows operating system load fully. Now, if your computer keeps rebooting itself even in the safe mode, there is a problem either with the operating system or hardware. And if your computer is not rebooting itself in safe mode, the problem is related to certain software.

Over heating is another reason why your computer keeps rebooting itself. Not many people pay attention to this aspect though. The fan responsible for keeping the CPU cool, may be malfunctioning or there could be dirt settled between the fan and CPU. Any one of these could be the reason for your problem. Either clean the fan area, or replace it if necessary. Try providing proper ventilation for your CPU, so that it stays as cool as possible.

You computer could reboot on it's own if you have installed improper drivers. Right click on the 'My Computer' icon, and click on 'Properties' from the menu list which appears. A new window will open. Select the 'Hardware' tab, and click on 'Device Manager'. A list will be displayed on the screen in which you will have to check all categories. Is you see any red or yellow warning icons, make sure you update that particular driver from the internet.

I need to reboot my computer and when it starts up but i dont know how

How to reboot a PC.
  • Save work if it's in jeopardy. If your PC has frozen, attempt to save your data before rebooting your machine. Rebooting will almost certainly cause data loss. Attempt to save your data to your hard drive, diskette or portable media.
  • Step 2 Determine the steps your operating system has to go through to reboot. Some operating systems allow you to press Control, Alt and Delete to reboot the PC. Others require different commands. However, if the operating system and software are frozen, you may use the power button on the machine or the power strip.
  • Step 3 Use the power switch if necessary. If you cannot access the shutdown feature of the operating system and the relevant buttons still won't allow for a reboot, press and hold the power button on the PC. Allow the machine to rest for a few seconds, then power back on.
  • Step 4 Wait for the power-on self-test. Allow the PC to check its components thoroughly through the initial boot screens that will appear.
  • Step 5 Resume working. Log back into the machine and continue to work.

    You have provided some good information, but more detail is needed.

    Is the system still under warranty? How long ago did this start? Have you added any new hardware or software?

    Your reboot issue might not be hard drive or MBR related. Disconnect everything not needed for booting. Even disconnect keyboard and mouse to see if it will get to the Windows Desktop.

    If that works, start adding until you get the reboot problem again.

    If none of that helps and you need to recover data from the computer, buy or borrow a hard drive you can boot to for the computer and when you are able to boot to Windows, you can back up your important data, then wipe the drive and reload Windows or leave it blank as extra storage capacity depending upon your desire or circumstances.

    Let me know if you have questions.

    Computer wont stay started

    most likely its an over heating problem

    most of the time when the computer (CPU) is overheating the computer will shut down by itself to prevent the (CPU) from damaging.

    so all you need to do either clean the fans (internal and external fans). or maybe you will need to replace them.
