Might be bad memory. How old is it?
Test memory with a test in BIOS.

I got the computer new in spring 2010.
os: microsoft windows 7 home premium v 6.1.7600 build 7600
It's bios: insyde f.17 12/10/2009
Installed mem is 4.0gb
Tot Phy 3.75
tot virtual 7.49
avail virtual 5.54
page file space 3.75
is that what is meant by 'memory test' or is there something I should run?

yea usually there is a memory test if you boot into BIOS, under tests or diagnostic or something like that, and you run it and if it turns up any errors than you know its a bad stick of ram.
It could be the lcd though, try connecting to another external monitor or tv with vga cable and see if you get a picture.

Right now, I can open the screen normal with no problems, but if I push it all the way open, it goes black until I push it a little more forward. So, i know hooking up to another monitor would show a good picture.
is there somewhere on the hp website that will step me through the bios test?
Or, does it sound like it is an lcd issue?

I don't know but I think the screen goes black when there is no power so faulty ram or a loose cable are my main sucpisions.
Usually, to run the bios test, as the computer is booting up press F2 or Esc and it should be an option.

having the same problem with my DV5. HP customer service was absolutely useless since it is out of warranty. Waiting for a callback from a supervisor in the United States who may "actually" speak English and be able to understand the problem. Did you ever get a solution? [legal discussion removed]

Too late, they have already been sued for selling laptops with faulty displays several years ago. See Hewlett-Packard Company v. The Superior Court of Santa Clara County.
