I'm not sure what happened... I turned off my computer this morning when I got up for work cause I saw my wireless modem had messed up, and when I got back home I started it up. Everything went smooth, said it had loaded to 100% and then just froze on the loading screen for a solid couple of minutes. After no response, I rebooted. Now whenever I start it up it just says "Pentium 4" and goes to a black screen after that.
Any suggestions?

I was using Windows XP... if that helps. I doubt my specs do.

Specs always help!

I'd say power supply or hard drive failure first
