Did you remove your laptop battery prior to removing the RAM? I do not see that step in your description...

Nevermind, see you had the battery out from a few steps earlier... If this were a desktop, I could probably give some steps. A laptop is a lot more difficult to debug hardware issues, which this seems to be. Check the power connection to the motherboard; make sure the connector attached to the motherboard that the ac adapter fits in is not loose. Also, try with the battery back in the system to see if that makes a difference.

I'm not sure where to check the power connection at. Would it be right behind the RAM, or would I have to open the entire case?

And I tried running from just the battery and there was no difference. It does sound like it's trying to read the CD, though. I don't know if that means anything or not.

The power connection is where you plug your AC adapter into the laptop. There should be a little circle with a hole in it. Gently push on it and see if it feels loose.

What happens if you remove the CD? Does the system still fail to start?

Ah, I gotcha. No, the power connection feels pretty secure. And the computer still turns on fine.

But now there's nothing on the screen at all. And even if there was, I can only assume it would still be at the HP startup screen not loading anything.

Do you have any USB devices plugged in? When you did the steps that Greg suggested, did you do them with everything disconnected? i.e.
  1. Shut down and turn off the computer.
  2. Unplug the computer from the wall or surge protector (then remove the battery if it is a laptop).
  3. "Remove the computer from any port replicator or docking station, disconnect
    cables to printers or devices such as external monitors, USB memory sticks or SD cards, headset or external speakers, mouse or auxiliary keyboard, turn off WIFI and Bluetooth wireless devices." (Use Hard Reset to Resolve Hardware and Software Issues HP Pavilion dv5000 Notebook PC series - HP Customer Care (United States - English))
  4. Hold down the power button for 30 seconds. This closes the circuit and ensures all
    power from components is drained to clear the software connections between the BIOS
    and hardware and clear any corruption in the temporary memory.
  5. (If it is a laptop, plug the battery back into the laptop and then) Plug the computer back into the wall. Do not reconnect any unnecessary peripherals; monitor, keyboard,
    and mouse should suffice and be the only peripherals reconnected.
  6. Turn it on to reinitialize the software connections between the BIOS and hardware

After doing the above (if you hadn't already), if you still have the same problem, try connecting to an external monitor and see if the problem persists. That would rule out a broken screen connection.

Nothing has been plugged into the USB ports and the battery has been out of the computer except for when you told me to put it back in.

When I was taking the RAM out the first time, I didn't pay attention and the computer was still plugged in (battery was out, power was off, nothing in the USB ports, etc). I took on of the RAM sticks out, and the computer still ran, but stuck at the startup screen. Then I took the second one out and put the first one back in and nothing showed up on the screen. That's where I am now. I figure that must be what caused my screen problems.

But I did your 6 steps, and still nothing. I don't have an external monitor, so I can't really test those either. I do have an HDMI cable, though. You have to be able to get into windows and tell it to display onto the TV, though, don't you? If so, I won't be able to test that idea until Sunday.

The POST screen should show up on a TV when the system first turns on. Worth checking, though I have a feeling not unplugging is what got you in trouble. You probably fried transistors due to a power surge through components. I would guess the motherboard itself has some faults now based on the behavior.

That's what I was afraid of, but at this point it seems to make the most sense. I just don't know why it would have still worked after I unplugged the first one.

But it would definitely not be worth it to replace the motherboard for a computer that still might not boot the operating system anyway. I might as well spend a few hundred dollars more and just get a new computer. But I'll keep trying to fix this one at the same time, I suppose.

I had a similar experience with a Dell years ago, so I know what you're going through. Sorry we could not provide better news. If you have a hard disk enclosure, you can still salvage your data. If you do not, you could invest in one or see if a friend has one for laptop hard disks.

No problem at all. When I booted 'er up and couldn't get to the operating system I basically declared her dead. Had it for almost exactly two years, which is kind of a shame. It's not very long at all, but she certainly served me well over that time. Sure we had our disagreements and sometimes she'd blue screen on me. But this was my first computer and feel like I lost a friend. This is sad for me, as funny as that may be.

Anyway, I didn't have anything worth spending the time saving. I do want to make sure it's wiped clean, though, to make sure there isn't anything that someone else could get from it somehow. How would I go about doing that?
