What you're saying doesn't appear to work, Derby (or I missed something). I disabled the auto-restart option and I did not get any error reports on the screen when it went blue and computer froze.
BTW. Is the "automatically restart" option supposed to restart my computer when it freezes if it is enabled? I had to restart it manually even if the optopn was enabled.

I'm gonna describe the blue screen once more because I think some people thought it was something else.
This blue screen is not there because of an error or anything similar. It appears always when windows start up (It's a standard part of windows startup before the welcome screen). But the problem is the welcome screen doesn't show up. When I use the classic startup way a window pops up asking me for username and password. I can start windows normally in this case.

Are you sure this is a stop error?

Link: If CloneCD installs such drivers, doesn't system restore remove them? I still get the problem even if first I uninstalled CloneCD and then used system restore to restore it before the CloneCD installation.

The diagnostic startup appears to work. Windows start without any problems. It must be a driver or something...
