BSOD BCCode: F4

[Daniel Hadaya]

Hi!
Always when I shut down my computer after booting programs, there comes blue screen. I have tried changing my RAM sticks, but no help. People say it is a driver problem as the problem is shown as: ntoskrnl.exe. How can I solve the problem? Can I re-install windows without all of my data and pictures go away? I do not have a backup drive. I really appreciate your help!

Specs:
Amd Athlon II X3 460 @ 3.4GHz
MSI GeForce GTX 750Ti
Windows 7 Home Premium (activated)
8GB of DDR3 RAM
1TB HDD

Thanks

E: I have run memtest, no problems occured.

The version is Windows 7 and the language is Finnish, as it is my native language. If you need something to translate, I can tell it to you
