lsass.exe boot up problem

[Guest]

I hope someone can help
Recently I upgraded the RAM in my computer. It used 256mb DDR bus 266 and
after checking some related sites I decided to upgrade to 512mb DDR bus 400,
since I read that DDR is retro compatible. But now when I boot my computer it
stops right after windows is about to load and a this message appears
"lsass.exe error. indicates ACL structure not valid". I can't even load
windows in safe mode cuz just as it's loading, the message appears. I have
some important data in my hard drive that I need to recover but even using
the hard drive as a 'slave' in a different machine has proved useles for when
I try to access the folder with the data a message saying 'acces denied'
appears.
Can anyone shed some light on this plz?

The RAM you bought is not compatible. Read the manufacturers suggested RAM type and follow
it to the letter.
Return the RAM you bought and get the recommended RAM.
