Please help to recover missing file

N

newbie

I am faced with a strange problem.
I was working with worksheet in Excel when there was a power shutdown.
The worksheet was in saved condition.
When power resumed my worksheet simply vanished.
Now whenever I try to access the worksheet I get the message that worksheet
could not be found.
As my pc is window xp pro. the worksheet should have saved itself as it does
in word program.
I have cheeked Recycle Bin and ran search program without any success.
System Restore is of no help as it was off.
Is there any way to retrieve the file.
TIA.
