I booted up my computer and got onto the boot screen for Windows XP Pro then a window popped up and said:

lsass.exe - system error

an invalid parameter was passed to a service or function

So after you click OK, it reboots and its a cycle of this..

I have already tried Safe Mode, exact same thing happens..

I tried using Windows XP Boot CD, Last known good configuration, that didn't work.

I can't get onto my computer at all.

If the only way is to reinstall Windows XP, my harddrive is on a partition, is there anyway to not wipe out files on one of the partitions, the one that doesnt have Windows XP files, just personal files.

I can't run an antivirus or anything, Windows XP wont boot so I cant run any programs.

Thanks for your time and help.

P.S. I'm currently using a public computer.

Hi Arty C...

Try this REPAIR to your installation of XP. This procedure will not damage or change your current files or settings...it will just repair or replace damaged system files. You will be asked for your Installation CD and may be asked for your product key. Follow the instructions carefully...print them out if you can. Note: This option is not always available on OEM Recovery Cd's

Once this repair has completed, you will have to download all Windows Updates again.
