Use !analyze -v to get detailed debugging information.

BugCheck 3B, {c0000005, fffff960007c0a85, fffff8800288eae0, 0}

Probably caused by : cdd.dll ( cdd!DrvMovePointer+b5 )

Followup: MachineOwner
you have a number of different dmp files although many contain the above error. The cdd.dll quoted above can mean a number of things, it's a microsoft display driver (or part of) and it's appearance can signify either malware, corrupt files or hardware issues.

Your missing a service pack. Either run windows update or download the service pack here:

If you have issues installing the service pack run this update readiness tool:

Once the service pack is installed you'll still need to update windows so run the update application again.

BiosVersion = V3.0
BiosReleaseDate = 11/24/2011
Your Bios needs updating. Please check motherboard web page:

dtsoftbus01.sys Thu Jun 20 08:22:51 2013: Daemon Tools driver, possible BSOD issues in Win7. Please remove to test.

Rt64win7.sys Thu Feb 16 05:39:50 2012: Realtek Gigabit Network driver. Please update:

If the cdd.dll file is just corrupt a system file check should fix it. Find cmd prompt via the start menu. Right click on it, choose properties and then run as admin. Type:
sfc /scannow
Press enter and await results.

If you still bsod after updating the above test RAM using this app:
Run for a few passes.

Post any new dmp files.

Hi kemical, tnx for quick reply.

-I have installed Windows 7 SP1.
-Bios version 3.2 installed with Live update tool.
-Daemon Tools uninstalled.
-Realtek Gigabit Network driver updated.
-When I run sfc /scannow it says: Windows Resource Protection did not find any integrity violations.

Will see what will further happen.

Tnx again!

Just one more question, how long should i take memtest? How many passes, or hours?

just do about 3-4 passes but only if you get another bsod.
