Aaaaaaa thank god. Not sure what was the problem,but i reinstalled Windows again and installed SP1 in Safe mode. After that MSBlast and Sasser patch and now it seems to work fine (10min connected to net,also 20min in windows). Still not quiet sure what coused lsass component to fail ??? Thanks igor,for your time :slight_smile:

EDIT:
I was talking too soon. After installing soundcard drivers,i restarted and boom on next boot that thing came up after a few minutes. Reboted again and now its working again. Hopefully. Currently updateing windows on Windows Update,hoping for the best.
