BSOD randomly, been occurring for a long time now, now more frequently

[xxratedxx]

I am having some troubles with my computer because of this issue. Now nearly daily my computer crashes and a BSOD appears. Usually this problem wasn't this frequent, it used to happen weekly though, but now it's irritating, I ignored it first, because once a week isn't that much, but now it's happening nearly daily, here's my dump file, I hope you can help me out please.

Thanks!

Shall I remove the CPU overclock settings too? Or the Video card only?
I have the latest BIOS Version too.

Now I've applied new thermal paste to the GPU and the CPU , so I'll see how it goes , this morning another BSOD occurred, but this is before I applied the thermal paste.
