Random BSOD's on Windows 7 64 Bit

Hello.

It's been 5 months I am having issues with my computer. I get random BSOD's.
1.Tested RAM with MemTest
2.Re-installed Windows with core drivers only

Basically I get random BSOD's with diferent messages.

My PC config is following:

Intel Core 2 Duo E6000 2.4 Ghz (NO OC)
Asus P5Q Deluxe MOtherboard
2xCorsair Dominator 2x1024 8500-C5D
2xCorsair Dominator 2x2048 8500-C5D
Asus nVidia Geforce 8600 GTS
Sound Blaster X-FI Platinum

Custiom Bios Settings I have (note that I get same or even more BSOD's with AUTO):

DRAM Voltage: 2.1V
NB Voltage: 1.40V
CPU Voltage: 1.325V

There must be some underlying piece of software that crashez, because I get different files in the dumps. I am unable to interpret them and find what is crashing these sys files.

I've attached the files you need from posting BSOD problems on this site

If you need more info, I will gladly give it to you.

Regards,
Sorin B.

The Asus P5 series of motherboards is very finicky about memory settings/timings/voltages. You cannot (as you've found out) use the Auto setting in the BIOS. It's recommended that you visit the Corsair website and find the settings/timings/voltages that are recommended for your RAM - then use those to set the settings in your BIOS.

Please visit the Windows Update site and get all available Windows Updates.

How long did you run MemTest for?

Please try this free hard drive diagnostic procedure: HD Diagnostic (read the details at the link)

Please update your Creative audio drivers from the Creative website. The one's installed on your system date from 2008: http://www.carrona.org/dvrref.html#ctac32k.sys

From what you describe, and from the different BSOD errors, there's a strong possibility that this could be a hardware problem. The BSOD's blame core Windows files, including those that work with the hard drives - so we'll start with the hard drive tests first.
