Analizing crash dump - windbg

I'm having an issue trying to find out to which problem is crash dump pointing. If someone could help me it would be nice.
This is what I get in windbg.

UDK error, how to examine crash dump

I am working on a game in UDK, and sometimes the game crashes when restarting the level or trying to open a new one.
I cannot find the problem trough the log files, they are just displaying a critical error.
Now I am trying to fix it by examining the crash dump, but I do not have a clue how to do this. Does anyone have an idea how I can further investigate the problem? I tried some things that I found online and this is what I have so far.

The most basic analysis in WInDbg is done with
.symfix
.reload
!analyze -v
Since it crashes, there should be an exception somewhere. Try
.ecxr
.exr -1
Also the call stack is potentially interesting. Since this is about UDK (Unreal Engine Development Kit), I assume it's written in C++ and thus we need a native call stack

windbg exception in sos.threads on first run

When I load a crash dump in windbg (x64), version 6.3.9600.16384, and load the sos extension for .net, the first time I run the !threads command I get this error:
c0000005 Exception in C:\Windows\Microsoft.NET\Framework64\v4.0.30319\sos.threads debugger extension.

Subsequent times the command runs fine. Full transcript:

This seems to be a weird issue caused by saving an explicit workspace which remembers which extensions are loaded. If I .loadby sos clr and save the workspace, next time I open the workspace it will have sos loaded twice. However if I do .load c:\path\to\sos.dll and save the workspace, it only gets loaded once when I reopen it.
In summary, workspaces in windbg are confusing.

How do I make windbg load clr.dll from a custom location?

I am starting windbg using the following command line:
C:\Program Files (x86)\Windows Kits\8.0\Debuggers\x64>windbg -i c:\tmp\Psscor4\amd64;c:\tmp\Psscor4\x86;c:\tmp;srv*E:\symbols*http://msdl.microsoft.com/download/symbols
C:\Program Files (x86)\Windows Kits\8.0\Debuggers\x64>
Then I load a memory crash dump and inspect where did it load the clr.dll from:

So, my question is why does windbg insist on loading clr.dll from C:\Windows\Microsoft.NET\Framework64\v4.0.30319 when both the image path and the symbol path direct to another location where sits the clr.dll that I truly need - c:\tmp?
Now, when I force loading of the symbols, then we can see this:
Loaded symbol image file: clr.dll
Mapped memory image file: c:\tmp\clr.dll
Image path: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\clr.dll
Image name: clr.dll
I do not like it. I want the image path to come from c:\tmp as well.
How do I do it?
The Image path shows where debugee (the process which were dumped) found the clr.dll.
Like it or not, it's noting you can do about it :-)

Sometimes Windows Crash while LabVIEW operator Advantech PCI-1716 card

The system include 2 Advantech PCI-1716 card:http://www.advantech.com/products/PCI-1716/mod_86EC4C4D-F497-45C5-81DA-B8600C0EB36F.aspx
I write a program with NI LabVIEW 7.1.
The LabVIEW program can control the two PCI 1716 card.
It work very good.
But about a year later, The computer crashed and sometimes auto restart.
Nobody change the software and hardware.
I used WinDbg to analysis the Windows crash dump file and I think I find something abnormal.
For the WinDbg result, I think maybe the PCI-1716 driver was broken so I re-installed it.
But the problem also happen.
And I also re-installed my windows xp.
The also problem happen again.
I don't know how.
Maybe the PCI 1716 hardware broken.
But how to find which one, there are two PCI 1716 card.
The WinDbg result is:

I'd run Memtest86+ just to see if you have any bad RAM.
Following that maybe you can pull 1 card out and write a simple script to do some I/O (similar to what you're doing normally maybe). If it takes a while you could put it into a loop and run it for a while and see if you can force a crash. You could repeat the test on each card to see if you have any issues with just one of the cards.
Does the crash happen often or rarely?

WinDBG: Unable to insert breakpoint 1 at 64b6ea43, Win32 error 0n299

I am trying to make a call to a method of a Windows COM interface from the Go language. I suspect I am doing something wrong in the way I invoke the call and would like to see how the registers change during the invocation.
But I have a hard time getting to it since I can't seem to set a breakpoint in WinDBG. The command "bu 64b6ea43" ends up not working with an error "Only part of a ReadProcessMemory or WriteProcessMemory request was completed". The full message is below.

To me it was problem because of ASLR.
running editbin /DYNAMICBASE:NO NameOfDetectedExe.exe fixed it.
Switched to Ollydbg which works. Learned that WinDbg sucks badly.
