HP DV6000 laptop not booting

[Arsey]

My friends DV6000 laptop recently stopped booting up properly. When he turns it on the lights all come on with the fans etc, but the screen does not display anything. After a few seconds, the laptop seems to reboot itself but with the same results. Sometimes after he keeps turning it on and off it will boot up as normal.

He has tried reseating the RAM and only booting with 1 stick but it doesn't seem to help. Any ideas?

Hey, does your laptop make any beeping sounds? My friend had a similar problem with his HP DV Media centre laptop, and his graphics card was borked..

There are no beeps on the laptop, just lights. He has tried taking out the battery and updated the BIOS. He restored it to factory settings and sometimes it seems to work faster but still not all the time.
