Hi, I have a problem. Today, I noticed that my Macbook Pro was running a bit strangely, with some video being slow and stuff, so I restarted it. I see a black screen while my laptop still on. I tried hard to resetting it, but whenever I keep turning it on, I hear the booting sound, but the screen doesn't turn on. What should I do? My mbp warranty has ended

Thanks wei, any news will update you.
