any water dipped into the mother board from laptop keyboards also causes failure,

high heat may caused the damage to the processor/mother board.

Early symptoms : high temperature & hanging due to heat, sudden shutdowns.

If you have voltmeter check the voltage of power cord & ac adaptor,

Incase of computer check smp by attaching two wires .

 

 

#8 incase windows not turning on

we deal with safe mode with command prompt,

reinstalling windows,

My laptop worked fine with ubuntu after windows install it failed,

 

Laptop /pc shutdown randomly

1st case: over heating /heat caused over work load.

 

Know the cpu operating temperature.

95c –

cooling system on laptop: thermal paste orlack of airflow due to dust.

solution: clean the dust & appy thermal paste to cpu.

(Mechanical thing)

install speed fan, cpuz to monitor the temperature status.(mostly ideal I guess)

 

 

2nd step:

 

 

Turn on the laptop /pc enter into bios mode. Keep 

It for few hours if system not restarted.

 

 

Then update the drivers for hardwares.

Chipset drivers. Gpu,usb etc

Bios update (not befecial)

chkdsk X: /f” and press Enter button. Replace X with the letter of your hard drive partition

 

 

Manufacturers websites

also bad sectors hdd using minitool, easeus etc lot of time it takes.

 

 

Use: crystaldiskinfo (software)

as older hdd gets it may has more bad sectors.

Scan hdd with softwares like hdd status.

 

 

Cleaneup with cc cleaner / fix registry errors

 

 

I don’t think registry errors cause random shutdown.

 

 

Memstats

Download software boot from usb.

Check it for memory errors.

 

 

If you bought a used/ refurbished laptops,

you the cases shows another model & mother board or windows sys info shows other model.
