BSOD - when use or shutting down

[kkl1016]

Well, my computer Intel Pentium E5800 has experienced BSOD for more than 2 months.
Sometimes, the computer restarts after i turn it off.
And sometimes it just cannot go to sleep after i turn it off.
Sometimes, the computer suddenly turns itself off when i browse the internet.
So, what's wrong with my computer?
I have attached my computer information.
Just let me know if you need any additional info. Thanks a million!
Sorry for my poor English
