BSOD - Page fault in non-paged area

I am very clumsy with PCs, I tried browsing the forum and I found so many different variations of solutions for this problem, I just don't know what to do.
I reinstalled windows 7 x64 recently and bought a new hard disk. Everything seemed fine for a while, and I bought a wireless adapter. After some time working on my PC I get BSOD saying page-fault in non-paged area. I checked if my hard disk is corrupted and it seemed fine, I suspect its either drivers, but I don't know how to check which are problematic and how to fix them, or it could be memory, tho I never had problems with it before. I have no clue what to do about it and its driving me mad.
