Powered on my computer this morning. Windows starts to load. Desktop image appears and bang. STOP: C000021a (Fatal System Error) The windows logon process system process terminated unexpectedly with a status of 0xC0000005 (0x00000000 0x00000000) The system has been shut down. Turn the computer on again and now it is normal. No minidump was generated and no system error in Eventlog was created. This BSOD never happened to me. Anyone?
