View attachment mini

Here is my mini dump. This machine was provided by my work. It's a referb that is outside of the 90 day window. I honestly don't know if there is/was a hardware on the issue on the motherboard that was never properly addressed, but I'm hoping that it's just a driver conflict that can be worked out. *fingers crossed*

Video driver is up to date as supplied directly by the manufacturer.

Help is greatly appreciated. I did watch the video at , downloaded the tool to view, and can see that in all the mini dumps (I have several) btath_a2dp.sys is the referenced problem but it's beyond me to know what to do next so I'm reaching out for help. Thanks.

Hi Xroads and Welcome to The Forum.

STOP 0x0000007E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (go to top of page)
Usual causes:
Insufficient disk space, Device driver, Video card, BIOS, Breakpoint with no debugger attached, Hardware incompatibility, Faulty system service, Memory, 3rd party remote control.

Your latest dump file lists btath_a2dp.sys as the probable cause. This is an Atheros Bluetooth Driver.
Old and incompatible drivers can and do cause issues with Windows 7, often giving false error codes. Random stop codes can often indicate hardware issues.

As a Priority:
