Computer keeps rebooting itself?

Question

as soon as the computer is done loading everything from start up, its goes on reboot, i cant keep it on long enough to figure out the problem... the actual tower does NOT shut off and no over heating is happening, so what would have my desk top of 2 yrs old reboot continually?? this started after i installed mcfee anti virus

Answer 1

Ok you should try unplugging your computer, and pressing the power button for 10 seconds. It should blink That means you reset it. Then turn it on. You need to do a system restore, so look at your menu when your computer starts up and press the appropriate key. I think for mine it's F5, not sure though, but look and read. Press that key until the window comes up for system restore. If you can't do that, maybe you have enough time when windows actually starts up to a system restore from the Control Panel. But firstly, do the first step of turning off your comp, unplugging and resetting.

Hope this helped. Good luck.

Hi,

Push F8 continuously when your computer start up, choose "Safe Mode" and scan it with lastest version antivirus because there're some system files in virus and deleted by Mcfee.

If not, Push F8 continuously when your computer start up & choose line mean 'last good know configuration.."

If auto reboot is enabled, turn it off.

To disable the auto-reboot, go to the control panel. Double-click 'System'. Click the 'Advanced' tab. Go to the 'Startup and Recovery' section, and select 'Settings'. In the System Failure section, uncheck 'Automatically Restart'. You should now be able to see the an error message which will help in diagnosing the problem.

Make sure all your fans are performing correctly also. If none of this works i would suggest uninstalling mcfee. When I installed it it didnt do this though, so maybe its just playing around with your computer.  If you get your computer running long enough hopefully you can do the things i suggested. I really hope this helps! (:

Answer 6

Try to start it in safe mode. You can do this by pressing F8 on most computers before the OS starts up in the BIOS page..... If you can get it to load from there go to Task Manager (CTRL ALT DELETE) > File > Run > MsConfig

From there go to Start up and turn all the Mcfee anti virus stuff off

if that doesnt work try to do a system restore
