I had a similar problem before. I'm not completely sure what I did about it, but if I recall correctly, it ended with a reinstallation of Windows.
That's a last resort, however. I just did that because I didn't feel like working out the problem. I didn't lost any stored data on my hard drive, but I reinstalled from a Windows CD. A restore CD would likely cause a loss of any data.
If you have any way to get hold of Windows Xp disk, I'd suggest trying the repair console. It's unlikely, judging by the problem, but you may have a corrupted boot sector. Still, I don't think it would boot into Windows, if that were the case.
Corrupted account data could cause that, I suppose, but I don't know for sure. Shutting down your computer while it's running can cause corruption of data, it's happened to me.
Try booting into Safe Mode. I'm not sure if that'll bypass the user account screen, or if it'll rectify your problem, but it's worth a try. If it boots into safe mode, there's hope for it.
