if it wont charge, it could be the charger itself or the port on the laptop. Verify that the charge works on another computer if you can. If not, i would start with the charger as it can be cheaper then a new motherboard or a new laptop. But try to find a way to test it first.
Could be bad LCD screen, defective video cable or bad motherboard. First, test the laptop with external monitor. If video on the external monitor is normal but it's bad on the laptop LCD, the problem is somewhere inside the laptop display panel (bad LCD, bad video cable, bad connection between cable/motherboard/LCD). If video on the external monitor is bad too, you have either software related problem or something is wrong with the motherboard. Try reinstalling Windows first, it might help.
