Use 7zip to compress it and post it here please.

Edit:
I have gone through your minidump but I am unable to come to any meaningful conclusion from just one minidump; which is only pointing towards (windows) ntkrnlmp.exe.

However, upon closer look, do you use kasperkey AV (or perhaps used it in the past)?; if so, perhaps uninstall it for a while and switch to Avast or Avira (both have free versions), and see whether that helps.

Lastly, upgrade your graphics drivers to the latest ones (you can find for your OS), you sound drivers, and your motherboard's chipset drivers.

If you get more BSODs, please do post all the available minidumps here. Also if you remember what you were exactly doing when these crashes happen can help.
