Please help with error

Hi.

Over the last few weeks, occasionally my computer will just shut down. But it's weird, it doesn't completely shut down, this little green light keeps blinking. I was thinking maybe it was some kind of safety shut down, but I didn't know what the problem would be.

Anyway, today this started happening more frequently. I was barely getting into Windows before it would shut down. Then, suddenly I started getting this error:

"lsass.exe - An invalid parameter was passed to a service or function. "

Then it restarts.

I can't even get into windows with safe mode.

I did a search here and found a few posts about similar problems with lsass.exe, but I thought maybe with the other things going on with my comp someone might have some idea what is going on and what I can do about it, if anything. Thanks for any ideas.

 

Due to the gradually worsening state of affairs, be sure to do a full virus scan.

If you have a Compaq or HP computer, read here for information on a patch:

(It appears that recovery on HP or Compaq requires a format and reinstall . Since this problem is so common, maybe they have a better idea.)

If you have recently installed SP1, you may want to uninstall it or do a repair installation with a full, SP1, slipstreamed CD:

and others.

 

It looks like This article deals with your exact problem and a fix.

 

Thank you guys very much, especially for that article. A question though, what is ntfsdos? Also, am I supposed to be following all of these directions from within dos? If so, can someone point me to a source that has instructions on how to do dos commands and syntax and everything. Thanks again.
