Laptop keeps crashing itself every 5 seconds

[DLTAFORCE]

So my laptop showed a notification that my OneDrive wasn't responding then it froze blacked out and restarted. After that it loads up then closes out and reopens every 5 seconds and I can't access anything fast enough to try and stop it

You need to remove the devices or apparels attached to your laptop.

Then hard press the power button for a long amount of time (atleast 20 seconds).

Then repeat the procedure two times.

Power on the laptop.

Press ESC every 2 seconds and then press F2

Then choose system tests and the option to do a check of your hardware.
