Blank Screen at startup..won't boot

Compaq Presario r3000

Specs: Windows XP
My computer has a long history of being a pain in the butt (the dreaded R3000), and I was hoping to get a couple more months out of it until I replace it for good. Already had the motherboard repaired and the connections resoldered for the famous "power cord not charging the battery" problem.

Anyway, earlier this week the thing froze, and it gave me the unwanted running of CHKDSK every time I turned the thing on due to "one of your disks needs to be checked for consistency."

Pressed for time, I kept going and didn't let it scan, which allowed the computer to run as normal, and I did this every time for a few days. I kept getting the CHKDSK prompt every single time I rebooted, and I kept hitting no, and the thing worked.

Finally, I decided to run a full CHKDSK as I hadn't done it in a while anyway, and the disk needed to be defragged but with CHKDSK scheduled to run, defrag would not do its work on the disk. So yesterday I ran the full CHKDSK, let it complete, the machine reboots and goes to Windows. I'm using it about 20 mins when it freezes again and I have to force it to turn off.

When I turn it on again, absolutely nothing happens. Turn it off, turn it on. Loads the Compaq screen and the XP logo, then freezes at the XP logo with the bar stopped. Turn it off, turn it on. Blank screen. It is important to note that the LED lights on the keyboard do turn on, and the fans spin, but nothing happens. Thinking it may be power supply related (that darn R3000...), I remove the battery and run it off straight AC. Same thing. I also notice that the CD Rom is making quite a bit of noise, but there is no disk in there. Figuring "maybe that's working" I stick the OS CD in there thinking maybe I can boot from CD. Again, blank screen, lights, fans, CD making noise, but nothing.

I really don't care a whole lot about the machine itself, I'm getting a new one soon, but I need to make sure my data is protected and was wondering what the best course of action would be to ensure no data loss. This sounds like a motherboard or ram stick failure, but I need someone who knows what they're talking about to let me know.

Computer itself is almost 5 years old. The HD is about 1 1/2 years old and showed no signs of any failure, and the power connections were resoldered about 2 to 2 and a half months ago.

Also, when my old HD crashed (the one before this one), the machine would still make it past the Compaq screen and would get to the XP screen where the bar would move but nothing would happen. It never went directly to a blank screen when I turned it on.

Please advise.

If this were a desktop system I would point towards power supply failing afraid I don't have much experience with laptops.

Practice makes perfect but only if you practice perfectly!

I'm having the same problem with Alienware m9700. was working fine until one day one problem led to another. Finally I got the black screen with auto-boot when I plug in the AC adapter and can't shut it off until I unplug it.

Please let me know how you fixed it when you do.
