Problem with unexpected restarts in 5 seconds of winlogon.exe and csrss.exe processes on Win XP SP3 (with all current updates via Windows Update service) 32bit. It can be during 1 hour until reboot...
It is starts probably with beta testing of NIS 2012 BETA in the april,2011. May be before it, with NIS 2011 (current).
It is about 2-5 times in a month and only reboot of computer can help. sometimes 1 reboot is not enough.
For now I have new copy of OS with NIS 2012 final installed. and on this new copy it is about 3rd time I saw it. Probably but not for sure it cause of NIS 2012.
It is taking place unexpected. may BE after 30 minites after start of PC. may be NOT during 5 days of constant using of PC. I have no idea why. after some program do something I guess - many different programs was last in use before this happend!
For now it was after 3-6 minutes after update of NIS 2012, that snapped here:
no my actions was - working with Google Chrome (updated) browser on typical non suspicious 3-4 websites like market.ya.ru, intel.com, ru.wikipedia.org.
Cause of what it can be? Strange behaviour on the new OS copy too... I do not know.
