Dell Laptop keeps going off on start

[decatalyste]

My dell laptop just keeps going of at will and in best case scenarios it hangs(freezes). Please need help

If it's shutting off after extended use it might be cooling related. Maybe get some compressed air into any fan outlets you can see.
If it's freezing and hanging, have someone check the internal drive for defects for you.

Couple of starting points..

Need specifics...model? OS? age? history of problem? symptoms? noise? Device Manager 'errors'? HWInfo report on temps and voltages (list highest temps and lowest volts from sensor range report - run for 20 minutes or more to gather some real history)?

May be a cooling issue...consider that it might be better to open case and do thorough cleaning (find a YouTube video on this for your machine model).
