Random freezes

[xTCx]

Hi,

I installed mavericks on my pc 2 days ago, and been enjoying it since.

Yesterday I had to install a patched AppleHDA for onboard sound - Realtek ALC887 (I have been using my GPUs hdmi audio until now but I need to be able to use the microphone jack).

Since then I've been experiencing random freezes.

It only happens when I use the computer, but not when I use a specific program (I mean, it froze when I watched a movie, or played around with the maps app, or when I was just surfing the internet, but it stayed on all night without freezing).

 

I also installed an app called "freezefix" but it didn't seem to help I guess (If I remember correctly, freezefix is supposed to fix freezes caused by the GPU... which proves my theory that it's actually related to the kext I installed).

 

Is there a way to find out for sure? and how can I possibly solve it without losing onboard sound card support?

 

EDIT: By freeze I mean I can't do anything but hard-restart.

 

EDIT2: Reverted to the original applehda, still freezing after 1-2 hours.

 

Build:

CPU: Intel i5 3570k

GPU: Sapphire AMD HD7950 3GB OC

RAM: 2x4GB corsair vengeance

MB: Gigabtye z77-hd4

 

Thanks!
