This desktop dell vostro turns itself on and off without the button being pushed. sometimes it makes it to windows, and seems to run just fine, then it goes to shutdown by itself... then turns itself back...


Well in the system Bios or setup there are options where you can have the computer turn itself on automatically at a certain time. However, the fact that yours is turning itself on and off seems to indicate that it is either over heating or it is running into an issue when trying to boot and it keeps recycling the boot process. There is an option that you can set that will turn off automatic restart on boot. Turn off the computer and then turn it on and start hitting F8 repeatedly until you see Safe Mode as an option. Scroll down through the options and you will probably see an option that lets you stop automatic restart on boot, and take it if it is there. This will allow you to actually see the error message that is causing your computer to reboot itself.

I have an e machine model t3265 it keeps just restarting i pressed the f11 button when i turn it on does nothing but keep restarting trying to get back to factory default help me please thank you also i...


Sorry to hear you're computer is acting up.

Turn the computer off.
When you turn the computer on tap the F8 key(at the top of the keyboard) once every second.
If you get the Advanced options screen choose Last known good configuration by using the arrow keys on your keyboard.

If the computer continues to reboot then do the F8 thing again but this time choose Do not reboot on system error(don't remember exact wording). If you're getting a blue screen, what is the STOP error code shown on the screen?

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.


Hello

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.

Computer will not run in safe mode (not in any mode). We had a power outage last week and ever since then the computer will not reboot or run. I get it cut on and a black screen appears saying that windows...


The power failure has made the operating system (windows)to crash . if you can do some installation on your pc yourself, you can repair the operating system or better still reinstall a new operating system.

I Need to reboot and i dont know how to


There are two ways. the best way is to click "start" then select "restart" (same as reboot).

this is a soft reboot because you never really power down the computer. You can also hold the power button in for a few seconds and it will turn the computer off. if it doesn't restart by itself momentarily press the power button once more.

How do you Reboot a computer back to factory setting


Instructions Things You'll Need:
  • Factory Settings CD
    How To Use the Restore Factory Setting CD
  1. Step 1 Make sure to transfer all of the files you want to keep to a USB memory stick or burn to a CD.
  2. Step 2 Put the "Restore Factory Setting CD" into the CD drive. This CD was packaged with your computer.
  3. Step 3 Confirm you want to restore the factory settings. The computer will begin restoring all settings. Don't disturb your computer, as this process can take several hours. .
  4. Step 4 Reboot the computer to complete the process.
  5. How to Reboot Using the Computer Start-Up
  6. Step 1 Turn on your computer. Right away there will be a black screen. You can restore factory settings without a CD, too. This will reset your BIOS.
  7. Step 2 Press "F1" when the black screen appears to enter the setup configuration mode. You will be presented with a menu.
  8. Step 3 Select "Restore Factory Defaults." That's it. Your computer will do all the work for you. Like the CD, this process may take several hours.

Computer keeps rebooting.


Hi there, maybe I can help.
As your computer boots hit F8, go to the startup menu and disable "automatic restart on system failure". Boot up and make not of any error messages.

Let me know if this helps

My computer keeps rebooting want allow me to go into safe mode only recovery. However upon restart it constantly reboots.


One problem can be that the router and net is on while you turn on your computer, so turn off the internet and router. Another problem is that its an annoying virus that forces the computer to restart itself.
