BSOD while gaming + streaming video

The crash only seems to occur if I attempt to stream video and play a game simultaneously. Curiously, the crash is a bluescreen in name only, as visually it's actually a black screen followed by loss of signal to the monitor. Minidump suggests tcpip.sys is the cause.

Windows 7 64-bit OEM
Asus P8Z68-V LE
Intel Core i5 2500k 3.3ghz
8gb RAM
500gb Seagate (Windows install drive) + 2tb Western Digital (for extra storage)
AMD Sapphire Radeon HD6850

All parts are less than 1 year old, Windows 7 installed fresh 26 December with many documents restored from previous backup.

Despite perfmon.exe's insistence to the contrary, I'm running Bitdefender 2012 for anti-virus services.

First, make sure Catalyst Control Center/Vision Engine Control Center is not overclocking your display card. If it is, turn off overclocking.

If the above does not stop your blue screen crashes, uninstall your display card and re-install using the following steps.

1. Download and install Driver Sweeper
2. Download the latest driver for your display card
3. Click Start Menu
4. Right Click My Computer
5. Click Manage
6. Click Device Manager from the list on the left
7. Click the + next to Display adapter
8. Right click your display/graphics card device
9. Click Uninstall
10. Check the box to Delete driver software for the device
11. Click OK
12. Restart your computer in safe mode
13. Run Driver Sweeper, select display card manufacturer's drivers, analyze, clean
14. Restart your computer
15. Install the latest drivers

Hi there, thanks for the quick reply. I tried the steps you listed and it doesn't seem to have helped. I created a fresh BSOD dump in case anything changed:

The performance monitor found some errors with the HD audio device this time around, which seems odd since the audio service seems to be running normally.

How did you get tcpip.sys? These are all related to your display card. It could be a memory problem. Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete.

Hi.

Just my 2 cents:

In addition to writhziden advice,remove Bitdefender from your system for testing purposes.


For now download and install Microsoft Security Essentials with windows firewall enable.

I got the tcpip.sys thing by viewing the minidumps in BlueScreenView; it keeps appearing under the "Caused By Driver" column in the top pane. I'm no expert on these things so I guess I just assumed it was accurate.

I've re-tried the removal and re-installing of my video drivers after removing Bitdefender and installing MSE. The crash still occurs so I'll run the memory tests this evening and post again in the morning.

Thanks for your help so far, 'tis much appreciated.

These problems sometimes occur due to file corruption. Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs.

Finished error checking the drives, still getting the crash.

I didn't start getting this crash until I started using this mobo and video card together; previously I had been using this same video card with an old Asus P5K without any issues. I'm not sure if that provides any extra clues.

You are not getting the STOP 0x116 error, but the steps in http://www.sevenforums.com/crash-lo...op-0x116-video_tdr_error-troubleshooting.html are very helpful for determining display card issues and may tell us if there is an incompatibility between the card and motherboard or a problem with the card itself (which is unlikely since it was working on another board unless it was damaged in some way during transfer [ESD]).

Not much luck in there so far though I'll keep going through the checklist. Furmark ran its Burn-In test for an hour straight with no issues.

BlueScreenView is also mentioning something called ntoskrnl.exe. I have no idea what that is though.

Both recent crashes\bsods points to gpu.


First read carefully this tutorial then run http://www.sevenforums.com/tutorials/160729-nvidia-amd-video-card-test-occt.html


Occt automatically create a folder with screenshots\results in your documents folder.


Let the test\stress finish,zip that folder and upload it here.


During the gpu test\stress have always in mind the temperature,if the temperature of your GPU exceeds 80C, stop the test.

OCCT isn't giving me any output files after testing (unless it's hiding them somewhere bizarre), and the monitoring function doesn't seem to work at all, even after installing Fanspeed. I assume I'm just doing something wrong but couldn't finding anything I missed in the tutorial.

I let the test run for an hour anyway and it reported no errors, but I can't find any output files to upload.

I prefer HWiNFO64 Download over fanspeed for getting hardware sensor information. You can start the logging in sensor only mode to generate a comma separated value (CSV) file that you can upload on here.

Run the log in HWINFO while you run OCCT, and also keep HWINFO logging enabled and go through the rest of the steps outlined in that thread for STOP 0x116 I linked in my previous post (the ones you have not already done, that is) and post back the results. You want to go through the first three posts in that link and follow each step closely until you have completed all steps that you have not already done to this point. I am with usasma in that I do not approve of registry cleaners, so steer clear of that step.

Good luck! :)

HWINFO output during the OCCT test attached.

I'll continue with that checklist as well.

I've finished most of the checklist now. I haven't tried reinstalling Direct-X just yet, and I don't have a multimeter to measure voltages with (though I can go out and get one if necessary). Ran sfc.exe /scannow, which returned normal results. Reset my page file according to the steps in the link. Crash keeps happening like clockwork.

I haven't tried streaming video from a different web browser (just in case that makes a difference) or by playing a DVD; I'll see if those also cause the crash, just out of curiosity if nothing else.

I had HWINFO recording during the last crash, the log is attached. I was running Dead Island while streaming youtube videos to reproduce the error.

EDIT: Tried using a different browser for video playback. Same old thing, got the crash.

It definitely appears to be display card related for the crashes, and it may very well be hardware related. When the crash occurred, the GPU sensors gave very strange readings. The fan's RPMs dropped to 0, yet the GPU sent that the fan was running at 100%. The memory clock changed from 1000.0 MHz to 3196.9 MHz, the GPU clock changed from 775 MHz to 13.7 MHz, and the GPU utilization dropped from 100% to 0%. Temperatures and Voltages look good.

It could be a faulty power supply (though as I said, Voltages look good, so I don't think this is the case), a bad motherboard slot, or the graphics card itself was damaged during transfer. The only way to really test these is to find another graphics card, another power supply, or use a multimeter on the power supply to rule them out.

I've opened a ticket with AMD tech support, I'm hoping I'll get an RMA out of this (because it sucks to go buy another video card just for testing purposes). I'd try my old EVGA 8800GT to test the slot, but it is sadly dead. If no RMA is forthcoming I'll get a new card to test (return policy permitting of course).

I'm going to move the card to a different PCI-e slot and see if that changes anything.
