Mecer z140c driver power system failure.

Hi, this is my first time asking for help so please bare with me.

Recently I decided to do a factory reset on my laptop which is a mecer z140c-edu and in the middle of installing the windows locally, it said an error has occurred and it needed to restart.

It been in this loop where it takes really long to maker it past the booting up and when it finally passes it. A blue screen appears with error driver power system failure before it does a restart again. There is no automatic repair. It immediately goes to the blue screen.
