0x0000007f BSOD on Windows 7 Ultimate 32 Bit

I used Nirsoft's BSOD Viewer and it said the caused files are:
fltmgr.sys
halmacpi.dll
ntkrnlpa.exe

My specs:
AMD Phenom II X4 955
2GB G. Skill 800Mhz DDR 2
3 HDDs | 3 CD/DVD/Blu-Ray Drives
ASUS M3NHT-Deluxe MOBO

- Yes, I've tried running memtest86+. I ran it overnight and there were NO errors.
- This is a fresh install of Windows 7 on a brand new hard drive (just installed 4+ hours ago).
- Even in safe mode, the BSOD's occur. They'll happen randomly; whether I'm transferring files, listening to music or just browsing the web.

Please, help !
