Hello I have a asus k7e3 laptop and it''s in pretty bad condition. I broke the keyboard and they I used a normal keyboard and I didn't like the touch pad because it was annoying. I took the flat connector out and then tried to put it back but it fried the wire so now the laptop turns on but my screen is black. I let it run I switched ram slots . the USB ports aren't working . it's just really bad. what shold I do?
