ataport.sys BSOD caused by WMP
So, I have done a clean install of Win7 RTM. I installed everything back onto my computer that I needed. I have tried to watch DVD's using Windows Media Player. I describe my results/progress/bsod:
Try #1: I click the autoplay button to watch dvd using Windows Media Player. Complete and entire freeze of system (no mouse, no keyboard...nothing until I hard power down laptop.
Try #2: I try click the autoplay button to watch dvd in VLC Media Player. I watched some of the dvd in fullscreen. I got out of fullscreen to do something and dragged the window slightly to the right; complete and entire freeze of system. I then un-installed K-Lite Codec Pack, thinking it to be a bad codec somewhere.
Try #3: I try again in Windows Media Player with autoplay button and it loads the DVD and plays it. If I get out of fullscreen mode and move the windows it freezes the entire system (as mentioned before).
Try #4: I try again in Windows Media Player (I believe this time with or without autoplay button) and when I tried to move the player at all I got a BSOD.
Try #5: Beginning to get a little frustrated at not being able to move a window while playing a DVD. I didn't touch the window and no problems. I watched several other videos off of the dvd without problems.
Try #6: I dragged the window tonight while in WMP because it seemed to be improving in capability. It made it over to the right computer monitor and stuttered before continuing to play (nice). Then when dragging back over to my external monitor, BSOD.
Yikes! I have tried to analyze the MEMORY.DMP files left behind in my system with the Windows Debugger program. All I can find relevant is that it is caused by ataport.sys and wmplayer.exe. The !analyze -v results are attached below.
I'm using Mobile Intel 915GM Express Chipset Family with the latest driver (6.14.10.4764). Dell hasn't made any updates for firmware for my DVD player either (Sony DVD+-RW DW-Q58A ATA Device).
I'm baffled at why ataport.sys would appear to be causing the problem--that's not a third party driver from what I can tell (it's from MS).
