Solved! Laptop Black Screen

[enryuu239]

I have a laptop that after the Lenovo title screen comes up the screen remains black and wont boot into windows. after many attempts of trying to get it to boot from a bootable usb drive (Even after changing settings in bios to Legacy) it would not boot from Usb. it would detect it but not boot. i opened the laptop up and reseated the Hard Drive and Ram stick and boom it started reading the bootable USB, however it was incredibly slow. i proceeded to format and delete each partition and made new ones. but after the second to last partition was formatted the Laptop sped up. the installation of windows continued and all was good i felt confident i had fixed the issues. but the following morning it was back to square one the laptop wont boot into windows after the Lenovo screen and sits on a black screen even though after re installing windows it was on for several hours just fine. Can anyone please point me in the right direction as to the cause of this issue?
