Solved! Asus x553ma startup errors

May 7, 2019
Hi all!

I have an Asus X553MA laptop. The other day, it started lagging, then the screen went crazy. When I tried to restart it, it started the automatic repair, but failed. Some attempts gave me the error saying ntoskernel error, and also the "a necessary device is not connected" error.
I connected another HDD, which keeps giving me the BSOD, and it also fails booting. The usb ports are also out of order, and the DVD booting is also a fail. Trying to install Ubuntu, it gave a cpu error.
Any idea what to do? Thanks.
