BSOD with unknown cause, possibly related to flash player

[melparsons0]

I'm troubleshooting a user's system that's having the occasional BSOD. Dump log attached. I wasn't able to get many details on what was causing the issue, but possibly related to watching online videos, so Flash. Apologies I can't provide more details. Running on Windows 7 x64 Home Premium. Help is greatly appreciated!

RAM - Test with Memtest86+​

   Tip

• :info: Pay close attention to part 3 of the tutorial "If you have errors"
• :tip: Test the RAM with Memtest86+ for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.
