lsass.exe - application error

[jobot2000]

Hey,

I am no longer to run windows, or anything on my computer. Everytime my computer is about to take me to the login screen, an error comes up saying

The instructions at "0x00401082" referencd memoryy at "0x00000000:. The memory could not be "written".
CLick OK to temirnate the program
Click on CANCEL to debug the program

Clicking on either results in a black screen for me that does not go away. I've tried running in the last successful startup safe mode, but it does not work.

Can anybody help me???

Use LKGC [last known good config], you get that option by using F8 at startup, AFTER the IDE/drive detection window comes up in BIOS.
The problem appears to be a password/logon hash corruption originating from I don't know what, but poss connected with the last M$ updates. The malicious sware rem tool? I don't know.

I have tried LKGC, the same error appears. any other ideas?

jobot, if you cannot start windows in any form it comes down to making a parallel installation on another hard drive, or in a spare partition on the problem unit, or slaving the drive in a well-protected machine.
Then? Run AV/AS progrms on it... MBAM, Spyware Doctor, online scans such as:
==Pandasoftware ActiveScan using IE or Firefox from http://www.pandasecurity.com/activescan/index/ - Register by supplying an email address, and follow through... To reduce the number of detections run either CCleaner or ATF cleaner first [to remove cookies].
==Kaspersky Online Scan, from http://www.kaspersky.com/virusscanner -press the Kaspersky Online Scanner button, follow through....
or http://www.kaspersky.com/service?chapter=161739400
==Bitdefender Online Scan using IE only: http://www.bitdefender.com/scan8/ie.html -use the Download button for the 30 Days Trial product; post the results, please.
I don't know if this is the result of an infection but if you get positive results from those scans we would love to see them.
==Please download Malwarebytes' Anti-Malware
from: http://www.majorgeeks.com/Malwarebytes_Anti-Malware_d5756.html
or: http://www.besttechie.net/tools/mbam-setup.exe
=Dclick that file, mbam-setup.exe, to install the application,
-ensure that it is set to update and start, else start it via the icon.
Select "Perform QUICK Scan", then click Scan; the application will guide you through the remaining steps.
ENSURE that EVERYTHING found has a CHECKMARK against it, then click Remove Selected.
If malware has been found [and removed] MBAM will automatically produce a log for you... do not click the Save Logfile button.
When it completes examine the log: if some files are listed as Delete on Reboot then restart your machine before continuing.
==Spyware Doctor from http://www.pctools.com/spyware-doctor/download/
or: http://www.pctools.com/mirror/sdsetup.exe
-install, update and scan.

Repair Install?

Out of curiosity, is it Isass or Lsass

I had this very same problem on a laptop where you could only see a black screen after boot up, with this pop up messages that winlogin.exe is not a valid windows image and some other M$ crap, and as suggested earlier in this thread, it is caused after a M$ update.

I am afraid, the only thing that helped were a repair install, from the second "R" option by rebooting from the XP install CD.

What amazes me, is that I suspect an update from M$ is causing this, and not necessarily a virus, and since I think 2007 M$ has done nothing to rectify this.
