Hi,
Are you able to access Safe Mode - repeatedly tap F8 as you boot?
This coud be a serious error and need tech support from a real computer shop (not leeks and peeks
at a BestBuy or other BigBox Stores) or your System maker's Support.
Go into Setup/Settings (BIOS/CMOS) often F2 as you boot so watch screen as you startup. Set the
boot order to CD/DVD to use Vista disks. Remember to set back when done.
With a Vista or Repair disk try Startup Repair - (the possible fixes are same as these though the titles
are named differently.)
This tells you how to access the System Recovery Options and/or use a Vista Disk

Try StartUp Repair from Recovery Options or Vista disk.

If you do not have a Vista disk you can borrow a friends as they are not copy protected. Your
System maker will also sell the physical DVD cheap since you already own Windows. Also you
can make a repair disk on another computer.

These "may" help :
Also from the COMMAND PROMPT of Recovery Console (if possible) or a Vista disk
SFC /scannow
Hit Enter
and after that runs
chkdsk /f /r
Hit Enter
( Spaces between C and / k and / and f and / )
Retry Startup Repair after Chkdsk.
If needed after those you can retry System Restore from the Recovery or Vista disk.
