Windows 8 RP constant BSOD

Hi, Im new around here, but I really need your help. Ive been having regular BSOD appear with the message DPC_WATCHDOG_VIOLATION within 5 to 10 minutes of starting my PC. The weird thing is that after I get the crash 2 to 3 times in a row, I can finally use my computer without any apparent problem. I have to do this like every session, and Im afraid of them doing damage to my PC, cause sometimes they sound horrible.

Im on Windows 8 Release Preview. This problem started some time ago, I cant remember the date exactly, but I used the RP without any problems for some months. I attached the zip with my info. Id really appreciate any help you can give me.

Thanks in advance.

Caused by you SATA controller driver, update it:

ATA NVIDIA nForce
fffff880`011cd000 fffff880`011f8000 nvstor Tue Sep 13 01:53:04 2011 (4E6E9B60)

I cant find how to update it, through device manager it says its already updated. What should I do?

You need to download a new driver from Nvidia.

This is really strange. I found the driver on nvidia website, and it has a bigger version number than the one I have installed (the windows default), but, it has an older date of release. I installed it anyways, and in the Device Manager it now says its out of date. Is this because of Windows 8 RP being newer than the release date of the driver?
