My laptop keeps restarting

My laptop keeps restarting and will not let me go to safe mode or anything. It keeps restarting. Has any one had this before? Know what to do? My memory is inserted properly.

Try replacing memory with a known good stick. Maybe your memory module is bad.

If you have two memory modules installed in the laptop, try removing them one by one. If the laptop still keeps restarting with each module installed separately, I guess it’s not related to the memory failure.

Find a voltmeter and test the AC power adapter, make sure the adapter outputs correct voltage.

Try minimizing the system as much as you can. Remove battery, hard drive, DVD drive, etc… If the problem still exists, most likely this is the motherboard failure.
