PC reboots when shutting down

Hi everyone. This is my first post here.

About a week ago my system frooze while I was burning a DVD. Ever since then when I turn it off, it will simply reboot. I disabled the restart on system failure feature to be able to see any blue screens. I got a bug check message and a minidump was saved. My system runs perfectly stable at all times, but produces this error everytime I turn it off.....
I have attached the minidump file. I would so much appreciate if anyone could help.

Thanks!

Thank you! I followed the links you provided and came to the conclusion that my registry was corrupt. Downloaded and ran TunUp and now it's fixed!
