Laptop keeps turning off

[19danny94]

Hey, I have a custom built laptop which keeps turning off at random sometimes it can last for an hour, or it turns off before it even boots into Windows. I have checked for Temps and they don't seem high to be causing any problems. A strange thing I've noticed is it will stay on all day if just left in the bios.

Any suggestions will be greatly appreciated thanks.

The motherboard may be bad. Any motherboard with the bad transistors will run if in the bios but will not run Windows or sometimes just turn off.
