I have a laptop Sony VAIO model VGNFS920, with 516Mb RAm, 1.73GHz intel processor.
it doesn't come with recovery cds, u make it from the partition it comes with or recover C: drive directly from there


I;ve been having this problem for a few days now and frankly i don't know what to do anymore.
at first i would get a message at start up saying
Isass.exe appliaction error. the system failed to initialize properly.click ok to terminate the program.
and then if would shut down or restart on its own. after a few times i would get the following message
STOP: c000021a {Fatal System Error}
The Windows Logopn Process system process terminated unexpectedly with a status of 0x00000402(0x00000000 0x00000000). The system has been shut down.
eventually i would be able to log in and the first message i would get is found new hardware ACPI uniprocessor Pc, and then rebooth so the system change can take effect. exept that rebooth might get me in the same problem.
i've tried doing a system recovery and for a while it ws fine and it did it again.
sometimes it would freeze at the vaio screen.
i just performed another c: drive recovery and at the first start up I got that blue screen again! that thing is driving me nuts!!!! :thumbsup:
if anyone has a solution it will be greatly appreciated. thanks

No solution...but I think it would be wise...to make a recovery CD, per instructions from the system manufacturer.

You may not always be able to access your hard drive or any partitions on it, the CD provides one more possibility of correcting whatever might be wrong (at that time).

Complex error message, multiple possibilities for what might be the trigger. You might want to read: http://support.microsoft.com/kb/156669/

Is it Isass.exe or Lsass.exe? Isass.exe is usually a virus.

That being said, the error that you describe is usually due to a corruption of the OS or a virus infection (which has corrupted the OS).
Here's a link to a description: http://aumha.org/a/stop.php#0x21a

I'd suggest a couple of free, online virus scans:
