Now, it happen already while winlogon.

The following programs starting during winlogon:

O&O CleverCache Version 6.1 Build 2332
TrueCrypt 6.1a
Proxomitron
PGP Desktop 9.9.1 Build 287

No one will be able to investigate and/or fix this issue unless you provide more details. To me it seems that you get BSOD and since you have enabled in Windows option to automatically reboot PC on such an event then it restarts automatically. You should provide minidump, and other useful informations like detailed operating system version you’re using.

Read this thread:

I assume you are a computer beginner.

I do not get BSOD (Blue Screen of dead).
No BSOD no minidump.
In this case windows option (autom. reboot) unimportant.
Event viewer: Computer restart unexpected.
In some cases OS (Operating System) does not create BSOD.

OS details:

still questions left?

meh… You may assume whatever you want. I just wanted to help you make a proper bug report, but if you’re intended to bark at anyone who have some suggestions about your original ‘bug report’ then be sure it won’t help to solve this problem.
