hello, i really need some help here. i own an almost 3 yrs old HP pavilion dv2713tx.

1. i think i'm having a display card problem with it as the screen goes dark after a while of me using the laptop but with the laptop still running.

2. everytime i tried to reboot i will have problem loading windows and sometime later, the screen just won't start altogether even with the laptop running (e.g. the lights are all on but not the screen)

3. once, some funny images (tiles of white and black boxes) appeared on the screen after i tried rebooting.

any suggestion as where to send them for repair to? thanks in advance.
