The PC keeps rebooting & rebooting itself frequently. Now we will find out the possible reasons & resolutions to prevent unauthorized rebooting of the computer.
1. Overheating
Overheating may be one the on of reason for this. If the CPU running over 60 degree (c) then it might be risk for occur burning issue.
Cleaning the heat sink & CPU is a solution for this. Keeping CPU in such place where enough air flow available.
2. Hardware Problem
An existing or newly added bad/loose hardware component may cause a machine rebooting again & again unless the component is either fixed properly or removed. However, the common hardware is as follows that may lead the pc keeps rebooting.
a. RAM
Faulty or loose system RAM may one of the reasons for rebooting the computer. Fixing the RAM properly or replacing it with good one may conclude the problem.
b. Motherboard
Malfunctioned motherboard may be another reason for that. Check motherboard if it’s in warranty period otherwise send it to servicing.
c. Hard Disk
Malfunctioned hard disk also may be one of the reasons for this. By replacing the hard disk with a good one may conclude the event.
3. System error & Recovery settings
In many cases windows may keeps restarting for system file corruption or system file missing or any other system error. For system file corruption check disk might resolve the problem. I personally resolved a great number of cases using check disk. For check disk use the following command in command prompt.
chkdsk %systemdrive% /f
It can be used the above check disk command if computer can boot using safe mode. Otherwise the victim windows loaded hard drive may be used as salve in another computer. In that case %systemdrive% might be replaced with slave hard disk’s system drive volume label.
For system file missing windows recovery might work which is by default turned on in Windows 7 but in XP it’s by default turned off. In Windows 7 it’s easy to recover corrupted windows by following the instructions provided by its self. For Windows XP where recovery console is uninstalled it might be required to repair windows using CD.
There are some other windows related errors that may lead to pc rebooting. To find enough information about those errors it’s required to uncheck ‘Automatically restart’ from ‘Startup and Recovery’.
In Windows XP, the default setting is for system failure or fatal error occurs then the pc take restart automatically. This option is also available in Windows 7. In this situation the reason of error could be find from event log. But if we turn off the default ‘automatically restart ’settings then it might be possible to see enough information about the actual error which would be helpful for further troubleshoot.
To change the default automatically reboot settings follow the instructions.
