PC won't boot up - LSASS.exe problem ???

My daughter's PC is not starting.
She gets a msg about LSASS.EXE and
P.S..... She also tried to get into Safe Mode (F8
or F3) but that didn't work.

Problem on boot up. Here's the sequence of events
Turned her Sony laptop on.
During boot up process is seem to hesitate, blue
bars were across the screen.
Then it continued the boot up process & got the
following error/problem
In a box it said, "This operation was
unsuccessful"
Underneath this line was another box within the
main box that said "OK". In the upper right
corner of
the main box it showed "LSASS.EXE".

She was not able to click on the ok as it
disappeared
almost instantly and the whole system died, power
& all.
It was like you turned off the laptop instantly,
not the
usual shut down sequences.

She had to do a couple more restarts to be able to
read the whole message down as it went by so fast.

I had her try an F8 to get into "Safe Mode", but
that didn't work.

Then she gave up and left it alone for awhile.
When she started
the laptop again all went okay, so I had her do; a
Disk Cleanup,
a Virus Scan with "vcleaner.exe" from AVG,
a"Spybot" scan and
a Defrag. No viruses or spyware was found be
either program.

She left it on as she decided to buy a USB Hard
Drive so she
could copy her files when she got home in case she
was
able to get a good boot again. When she got home
the laptop
was off again.

I'm trying to help her as she really can't afford
CompUSA or MS Help prices.

Anyone have any idea of what's going on and how it
can be fixed.

Thanks in advance for the help.
