Windows 7: BSOD when streaming to Roku 2 - ntoskrnl and tcpip.sys

It may have been Avast, and it may have been ASACPI. Both of which are known to cause blue screen crashes. Streaming video involves a network connection, and Avast may have misinterpreted the connection and caused a conflict. There also may have been a conflict with the streaming software and ASACPI.SYS.

If you want to try updating ASACPI.SYS and see if it fixes the issue, this is a good first step.

Thank you so much. I'll keep you updated.

No problem. Let us know if updating the driver fixes the problem and we can proceed with further steps.

ASACPI.sys is now updated to 5/14/09. I'll let you know if it happens again.

It just happened again after updating ASACPI.sys. It appears tcpip.sys is involved again, but it said the process name was PLEX Media Server, although I don't really put the blame on Plex since tons of people on Win 7 are currently using it. I ran the avast uninstall utility and installed Avira. Here's the dmp that happened today just to confirm my findings... Do you think I'll have similar issues with Avira? Thanks!

We'll have to wait and see whether Avira causes similar problems. Microsoft Security Essentials - Free Antivirus for Windows is really the only trusted antivirus on these forums and has been found not to cause conflicts on systems. If you continue to get blue screen crashes, consider switching to MSE at least to test. Then we can try narrowing down to other things if necessary.

Your .dmp file was pretty much identical to the seventh one I listed in the code snippet in my previous post. I added the debugging analysis to my post with the seven dump files, so now there are eight. I did note one more thing while I was working on that .dmp file.

Please remove any CD/DVD virtualization software, such as Daemon Tools/Alcohol 120%, as they use a driver called sptd.sys that is known to cause BSODs. Use add/remove programs to remove the software. After removing the software, use the sptd.sys uninstaller to remove sptd.sys from the system.

I prefer TotalMounter as my CD/DVD virtualization software as it allows me to burn images to a virtual CD/DVD if I just want an ISO file instead of a disc, and it is free.

Many use MagicISO - Convert BIN to ISO, Create, Edit, Burn, Extract ISO file, ISO/BIN converter/extractor/editor as well, which is also free.

So removing the software will remove the driver, even if the software isn't open at the time? I never have Daemon Tools open unless I'm installing something. Just making sure.. My judgement may be clouded right now... _ :cheers!:

Remove the software via the add/remove programs in Windows. Then use the sptd.sys uninstaller to remove the driver.

Daemon Tools Lite isn't listed in the program list... Should I be able to just delete spdt.sys from drivers directory and be good?
