Pure constantly crashing

[95BlackGA]

I've been having a problem with Pure crashing in Windows 7. It seems to crash because of 2 different things. Fault Module d3d9.dll, and ntdll.dll.

Problem signature:
Problem Event Name: APPCRASH
Application Name: Pure.exe
Application Version: 1.0.0.1
Application Timestamp: 48b6b73f
Fault Module Name: d3d9.dll
Fault Module Version: 6.1.7100.0
Fault Module Timestamp: 49eea4d4
Exception Code: c0000005
Exception Offset: 0001358a

Everything up to date, using a beta driver (I know this could be the problem, so I'm downloading the official driver now.)

EDIT : Looks like there's another...

EDIT 2 : Resolved, turns out it was a bad overclock, although I passed all tests... Some BS...
