Boot Problem on Vista Home Premium

Dell XPS 410 Desktop

Someone went through my computer today, making some changes, and now I can't do a lot of things as far as booting.

1. My computer sits on the first "DELL" screen for over 2 minutes, then it goes to the black screen with the white writing on (screenshot 1).
2. It also sits on that screen for a long time, but worse is what has started popping up on the bottom regarding SATA drive. If I press F1 it will go ahead and boot. I pressed F2 and took some pictures with my digital camera. See screenshots 2-4.

I ran Belarc advisor to see what it showed for Drives and that info is:
SAMSUNG HD321KJ [Hard drive] (320.07 GB) -- drive 0, s/n 0SEZ1JPN055368, SMART Status: Healthy
TEAC USB HS-CF Card USB Device [Hard drive] -- drive 1
TEAC USB HS-MS Card USB Device [Hard drive] -- drive 3
TEAC USB HS-SD Card USB Device [Hard drive] -- drive 4
TEAC USB HS-xD/SM USB Device [Hard drive] -- drive 2

I'm praying someone can look at these and tell me what was changed or disabled on my computer to make this happen during the boot.

I was thinking very strongly about using the Dell Factory Restore option, but I can't get to the screen. I think I reach it through "Startup Repair" on that F8 Safe Mode screen, but I can't get there.

I'm also considering a System Restore.

The computer is working fine except for these things.

PLEASE, please help!
