Windows 7: BSOD every 2 hours with new system.

Hello,
I bought this system last September, I handpicked all the parts myself. From first day I get random BSOD about every 2 or 4 hours.
This happens when I am gaming or even just browsing and watching video. Since then I have tried allot of stuff except for changing videocards or other hardware.

Some stuff I have already tried:
- Memtest86
- Prime95
- checked temperatures cpu/gpu
- OS is up to date
- Reinstalled a different OS same problem
- tried some voltage tweaks in bios on serveral components




OS: Windows 7 Ultimate x64 (tried Win XP x64 aswell)
CPU: AMD Phenom II X4 955 Black Edition
Motherboard: Asrock 870 EXTREME3
Memory 4GB Dual Channel DDR3-kit: GeIL GV34GB1333C9DC
Graphics Card: Club3D HD 5850 1GB
Sound Card: Onboard
PSU: Seasonic M12II 520W
Cooling: Scythe Mugen 2 Rev. B

Hi.
Ur most recent minidumps points to LUsbFilt.Sys,EX64.SYS and atikmdag.sys errors.
LUsbFilt.Sys is a logitech mouse driver error,EX64.SYS is a norton driver error and atikmdag.sys is ati graphic card error.
Download the most update driver from logitech Logitech.
Uninstall the mouse driver,clean with ccleaner CCleaner - Optimization and Cleaning - Free Download.
Install the new mouse driver.
Download the newest catalyst http://support.amd.com/us/gpudownload/Pages/index.aspx
Uninstall ati catalyst,clean with ccleaner,install the new catalyst.
Unistall norton,again clean with ccleaner,DONT install norton, install MSE http://www.microsoft.com/security/pc-security/mse.aspx
(If you like you can try one step at the time,wait for results and continue,my opinion,remove norton first)
----------------------
I notice that you have PSU: Seasonic M12II 520,seasonic is a good psu,BUT 520W is a little weak for ur system,this may gives troubles.
A psu update is definitely a good idea.
-----------------------
Please post back with any results!

Thanks for replying. Ill take your advise and see what happens.

Remember,post back with any results!

Hi again,

I have some new test results.

My brothers geforce 9600gt didnt help (because of the ati error I borrowed his)
I have done all steps above as well, lastest logitech drivers, no norton but ms security and did a full scan.

Also I looked into the Seasonic PSU; I have tried a watt calculator on this page eXtreme Power Supply Calculator
The result of that my system requires atleast 420 watt.

Those were the results. Im planning on a hard drive scan. I never tried that before because those worked fine the day before I bought the mobo, memory, CPU and GPU. It could be a coincidence though, for example: my onboard sound is now not working anymore from the moment I inserted my brothers GPU and its still not working but I still have a PCI soundcard thank god

Edit: extra minidump from 30 minutes ago while playing a videogame.

Did you have enable both onboard and PCI soundcards at the same time?

No its a cheap pci card that I bought 6 months ago when I was suspious about the onboard sound causing the bsod. I had disabled onboard sound in the bios at that time, just like I have now. But the PCI sound card has been in a box for the last 6 months.

The new minidunp points to ntoskrnl.exe.
For possible solution please read these:
NTOSKRNL.EXE is missing or corrupt.
Error message: "Windows could not start because of a computer disk hardware configuration problem"

hello a quick update

i have been checking this NTOSKRNL.EXE is missing or corrupt.

- I have sf /scan and it reported this: errors were found but was unable to resolve all of them....

- Did a large harddisk check on the one with my OS on it but no errors.

- Another memberycheck 10 phases no problems.

I do not have been able to get a spare keyboard so I couldnt test that and windows 7 doesnt seem to be having a boot.ini file, so that one cant be corrupt.

I have also downloading WinDbg and noticed that I was getting the following errors in my minidumbs:

dxgmms1.sys, ntoskrnl.exe and also when Im not using my brothers nvidia gfx, I get the atikmdag.sys error.

The newest error is LUsbFilt.Sys (Logitech USB Filter Driver)
Download the newest setpoint from http://www.logitech.com/
Uninstall setpoint,clean registry with ccleaner,restart.
Install the new setpoint,restart.
