Well after about 20 mins or so sometimes even after 4 mins the computer starts getting crazy like a disco. it starts becoming black normal black normal black normal in a quick motion, it really makes me mad cause i have to keep clicking the power button to turn it off, someone told me that the laptop's lightbulb might of be running out, but i just bought this laptop 3 years ago.. and it makes me really angry.. i got no idea what it might be, might be some sort of malware?? i'm not sure.
