Hello and welcome to Bleepingcomputer.
The problem with your computer is you have corrupted some files.
This happens when you shut your computer down the wrong way, the files are removed form the hard drive and become stored in your RAM, RAM is a temporary storage that loses the information it has stored once the computer is shut down improperly.
Normally when the computer is shut down correctly, these files are safely sent back to the hard drive where they are stored permanently.
When a computer is shut down incorrectly, the files that are actively stored in RAM are lost for ever.
When enough files are lost that are needed for the computer to operate normally, it starts running a check disk utility in an attempt to recover the lost files.
Sometimes this is possible and sometimes it requires a little bit more help to accomplish this task.
If you can get your computer to start up and choose command prompt, you can run the system file checker utility, which scans and repairs corrupted files.
To do this, boot up your computer and press the F8 key at the windows splash screen, choose load windows with command prompt.
At the command prompt, type the following bold text. SFC /SCANNOW Please notice there is a space between the SFC and the forward slash /
This should scan your OS files for corruption and attempt to fix the errors.
I realize you said you do not have an OS disk, using any Vista install disk from a friend should work if a Vista OS disk is needed.
