BSOD playing LotRO MMORGP, error 0x00000050

[Sionachai]

Hi -

I have recently rebuilt my machine after experiencing frequent BSOD 0x00000050 crashes when playing Turbine's Lord of the Rings MMORPG.

History: I had previously read through your forum threads (a valuable resource if ever there was) and other sources on this error, updated drivers to most recent, switched out anti-virus to recommended Microsoft Security Essentials, cranked down the graphics settings, and other various tweaks, etcetera etcetra, and after still experiencing the same error threw my hands up in despair, re-installed the OS from scratch, installed all drivers from scratch, finished installing all the MSFT updates, and was playing game with nary an issue until...

The BSOD 0x00000050 struck again this evening, twice as is.

Running BlueScreenView I did note ntoskrnl.exe was flagged in both dumps. The driver dxgkrnl.sys was also flagged in the second dump.

I have not yet run MemTest86+ but I will start the process anticipating it'll be needed.

So, enough about me... please find attached the necessary zipped dumps and my great appreciation for your insight and assistance. Thank you in advance.

Both your dump files directly blam the driver ctoss2k.sys Driver Reference Table - ctoss2k.sys look into updating this or if not possible for testing remove it

Hi Pauly

Thank you for responding.

I have installed Creative's most recent drivers as per their instructions. I noted the general version driver both before and after the install has not changed; 6.0.1.1348 dated 7/7/2010. Although I did not note the specific version of ctoss2k.sys prior to installing (sorry) I note that it is currently; 6.0.1.1348-2.17.4020.

I also looked back to the LotRO forum for BSOD issues with Creative SB X-Fi Titanium drivers and found several threads. Seems I'm not alone and it has been an ongoing problem for two or more years!

I note that a key thread refers to the more recent (12-12-2011) beta instance of the driver. I'm trying first with the supported release and then playing long enough to see if issue is resolved. If not, then I'll go with the beta instance.

I also noted one thread in the LotRO forums recommending disabling EAX and setting the software sound playback in the game audio options. I'll try this also as a third option. I only mention this detail in case another lost soul from Middle Earth comes across this thread.

I'll post back with results.

BTW, noted you're in Old 'Blighty. Devon no less. I'm an expat living in WA State and missing home quite a bit these days. Though I'm visiting family in Hertfordshire and Cotswolds next month so musn't grumble. Raise a pint of scrumpy for me in the meantime. Cheers and apologies if that was all TMI

Playing LotRO today - the first long session I'd had since my post above - I hit the 0x00000050 BSOD again.

As planned I have now updated to the beta driver. The version has not changed for either the main driver or the ctoss2k.sys driver but I do see the new date showing as 8/11/2011.

I'll continue forward for a few days and post again if there are further issues or resolved.

 

[Sionachai]

That did not last long.

However, this time I have a hit a different BSOD error; 0x0000007E.

I've attached a new dump of the log files and attached it here.

Well see for yourself the output of your dumps one = 0x50 (again) and the other = 0x100007e
Original issue still blames ctoss driver and new dump blames fvevol.sys this is quite strange as it is a windows provided driver and relates to bitlocker drive encryption which is quite unusual

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
This is a very common bugcheck.  Usually the exception address pinpoints
the driver/function that caused the problem.  Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003.  This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG.  This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG.  This will let us see why this breakpoint is
happening.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff80002e81ea0, The address that the exception occurred at
Arg3: fffff8800336ff08, Exception Record Address

Unfortunately i am unable to extract a finite cause for your issue from your dumps files as is often the case so i recommend you go the long route and start by proving all your hardware/software upto you which order you do it in

First off if your OCing in anyway stop, return everything to stock settings for the purposes of testing

If you havent already, fill in your system specs so we know what we are dealing with
http://www.sevenforums.com/tutorials/180324-system-info-see-your-system-specs.html


Make sure you have read the guide on asking for help with BSOD so you know what we need
http://www.sevenforums.com/crashes-debugging/96879-blue-screen-death-bsod-posting-instructions.html


And if necessary set your machine to create minidumps (Method 2 Step 2 is easiest IMO)
http://www.sevenforums.com/tutorials/174459-dump-files-configure-windows-create-bsod.html


Run some scans to check against virus or infection
