Question Computer randomly restarts about once per day. Possibly from Bluetooth dongle


Apr 11, 2015

I have had this issue for about a week now. Every day at a random time my computer will completely restart instantly with no warning or BSOD. I got a minidump from the first time that it happened but windows has not given me another since the first time.

This is what I get when I analyze the minidump

The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL
or above.
Arg1: 0000000000000000, A single DPC or ISR exceeded its time allotment. The offending
component can usually be identified with a stack trace.
Arg2: 0000000000000501, The DPC time count (in ticks).
Arg3: 0000000000000500, The DPC time allotment (in ticks).
Arg4: fffff804408fb320, cast to nt!DPC_WATCHDOG_GLOBAL_TRIAGE_BLOCK, which contains
additional information regarding this single DPC timeout

After seeing this I assumed it was an issue caused by the USB Bluetooth dongle I have in my computer that I use for headphones. I have tried reinstalling the drivers for it but the issue is still happening.

If anyone has any ideas on how to resolve this or if you need any more info about my system I am happy to provide it. Thank you!


Can you pass a link to the BT adapter that you're working with? To me, it looks like a driver issue with your USB port(s). Might want to also include the make and model of your motherboard and it's BIOS version at the time of writing. Make and model of your PSU and it's age?

Hey there sorry for the late reply. The BT dongle is a "Kinivo BTD-400 Bluetooth 4.0" (I think). My MOBO is an MSI B450 Tomahawk Max running on bios version 3.E0. I also have a 1000 watt EVGA PSU. Not sure of the exact model but it is less than a year old.
