Linux system rebooting automatically every 1 minute [closed]

Solution 1:

This particular problem is frequently caused by a bad RAM stick. If there is a bad RAM stick something in the onscreen boot messages will usually report it, however there might not be enough time to read all the boot messages because the computer reboots after 64 seconds. Even without reading the boot messages it is possible to troubleshoot this problem by removing the RAM sticks one at a time if there are more than one RAM sticks, and testing if the computer is able to boot normally when one RAM stick is removed.

If you have successfully found a bad RAM stick, the next thing to do is to remove the RAM stick from the computer, and take it with you to the computer store when you go to buy a replacement RAM stick to make sure that your new RAM stick will be compatible with the old one(s).
