HP Pavillion DV5000 Log In Issues!

Hello,

I got this HP Pavillion DV5000 not even a year ago yet from eBay, I know shame on me buying a crappy laptop from a auction site, but I was desperate. Now hear me out,
The laptop worked perfectly fine until randomly one day it crapped out on me. It would load Windows XP to the log in screen and from there it would do nothing... For hours I would let it sit and still nothing. The screen and everything was on, but I didn't understand what was going on. The laptop would boot perfectly fine in Safe Mode and I tried a System Restore, which never works. I dunno why I even bothered with that. Regardless, I eventually transferred all my stuff to a external hard drive and then proceeded to wipe the machine and it worked perfectly fine.

Now, a couple weeks ago, it started doing the same thing again. This time however, It doesn't even go to the Log In screen. It'll load the XP Logo incredibly slow and then nothing, but a black screen with all lights and fans going. I can also hear the hard drive working as well. Again, the laptop will start in Safe Mode perfectly fine, but no luck anywhere else. What's different from last time though is that, the night prior to this happening the 2nd time. Windows had a update as I shut the computer down and installed it. So I figure that might be the cause, but I'm not 100% sure. Please help guys, I rather not wipe this machine again. I mean I do have other PC's but I rather not sit in my room all the time. :(
