Hydro Failure - Now pc won't start

I'm using Windows XP SP2. We just had a storm and a hydro power outage for 10mins. My desktop was on at the time and when the power came back on it tried to boot up but I received the "We apologize for the inconvenience, but windows did not start successfully, etc.....

I was given the options of starting using:
-Safe Mode
-Safe Mode with Networking
-Safe with Com.Prompt
-Last Known Configuration
and
-Start Windows Normally ... which was highlighted.

I tried all of the above several times and it seems to try to start... I get the " XP Welcome screen" then back to the above.... just going aroun in circles.

Anyone any ideas here ???

Much appreciated.

 

Was the PC plugged into the wall or into a surge protector?

 

It was plugged into a surge protector...

 

Can you get into Safe Mode with Command Prompt?

If yes, login as Administrator & type :
fsutil dirty set c:
Press Enter.

Reboot & let Windows check the disk. In 90% of cases this solves the problem.

 

I cannot get into Safe Mode from the Command Prompt.

It has been suggested that my XP is now corrupt and it will need a XP Repair Fix (?)
