Hp dv2000 4 beeps, blank screen

Hello,
My hp2000 is out of warranty the screen recently turned blank when I reboot it it beeps 4 times but fans run and lights work. This happened before but after the next day it worked fine. 3 days later, today, the screen in the middle of use, showed vertical lines all across screen and shut down. I tried removing battery and all that if you have an answer please
