Startup screen goes black except for the cursor

That message says that the hard disk was found but nothing on it can be used - Vista is completely corrupted. You will have to reinstall it using the recovery cd that came with it when you bought it.

Hello,
The Operating System in your hard disk gone corrupt, you need new installation of Operating System using boot from CD/DVD.
P.S. Formating of Harddisk is recommended, because it seems the act of virus infection
Good Luck
DO rate if helps

This sounds like the dreaded Windows Vista Black Screen of Death (KSOD). you might have a bad hard drive, but even more likely some software or a driver is causing a problem and caused Vista to get stuck. The repair will not work. You might be able to run a complete repair from the Windows Vista CD, if you have one. If you are not too experienced, take it to a reputable computer service center. If you are at all technical and have time, google your problem and you will see thousands of similar users with same problems.

This is one reason Microsoft released Windows 7 so soon.

If you have the original Vista DVD that came with your computer, try running startup repair on your computer using the instructions here:

If startup repair doesn't work, make sure you have not modified system files such as authui.dll. I happened to have the same problem once on my computer :)
Try running this command in command prompt using the Vista DVD... sfc /scannow

try to hit win at keyboard, or ctrl+alt+del, if not working try safe mode(F8) and select recovery

Usually this happens when the vista boot loader fails. During boot up, keep tapping F8 and then select Disable Automatic Restart... and get the stop error code which usually starts with 0x

when digit the password to initiate does not initiate and it gives the following message me:
The User Profile Service service failed the logon.

In this case you have to do the PC restore . you can do that in dell machines by shutting down the machine and when it is coming back on just HOLD DOWN THE CTRL ket and the START HITTING f11 key in this case you will lose the data which you have the on the c drive but this issue will get resolved .

Else you can try to restart in the safe mode with networking and then go to the system restore and then select the bold dates in which you have idea you system was working fine . selct the date and then do the system restore . In this case you will not lose the data but you will lose the updates which you have done after that date .

in both the cases system will work .

simple, insert the CD XP boot it on using it, then repair wait for a moment, then it give you options which is either to repair your OS or install it again. thats it
