Guys, My lenova b460e laptop fell down heavily which resulted in display cracks. So I changed the display by myself, it worked.
But now my screen freezes with various colour being shown while freezing, and I am sure that there is no problem with my display.
Occationally it wont boot up, means, even the bios screen is now shown up.
Please suggest me a solution. Is RAM the main culprit ? ?
