We have been expreiencing multiple HP PCs and HP Laptops bluescreening with a "Stop code: DPC WATCHDOG VIOLATION". WE have tried all of the following steps, and eventually the only resolution is restoring the PC to it's out of box condition. Has anyone else been expreincing this issue?
Steps that we've taken
-restore PC to date prior to most recent windows updates
-running all windows updates
-updating PC/laptop firmware
-updating all device drivers
To date we have had to restore approximately 10 machines - combination PC/Laptops. We only use HP brand products, so I don't know if this is also happening with other brands.

Some time ago, I'd had a DPC Watchdog error and the fix in my case was to reset Watchdog to a longer period for error correction to run. In that case I suspected- without exact evidence, the problem was driver conflict. At the time, an IP friend said the most common problem were drivers.
The fact that so many of the subjects systems had the same error does suggest a common cause.
The article linked below seems to be a good, broader overview to the problem:
As the subject systems seem to have gone through a quite thorough set of attempted repairs, the list of possibilities and procedures in the link above may provide some additional perspective and/or eliminate some porssibilities.
This is a wild guess, but the mention of the IDE ATA/ATAPI Controllers drivers might be looked at for update if that was not done previously. If the reinstallation was done from a fresh ISO, those and other drivers may be updated and that cure will last, but if there is a single cause, that may save having to do the additional reinstalls.
Was the BIOS updated in any of the subject systems prior to the reinstall?
I'd be interested to know what happens.
