So I only get the DPC Watchdog Violation when using Deluge while connected to my VPN (PureVPN via the desktop program). I have no issues when using Deluge without the VPN. I have tried changing the hard drive drivers to no avail. These are the steps that I followed:


When you upgrade from Windows 7, or Windows 8, 8.1 to Windows 10, sometimes, you may get this annoying BSOD error. It occurs because of the iaStorA.sys driver that isn’t fully compatible with Windows 10.

To resolve this BSOD error, you can replace that problematic driver with the storahci.sys driver from Microsoft. Here are the steps you need to follow:

Press Windows + X and then press M to bring up Device Manager.

Locate and expand the “IDE ATA/ATAPI controllers” option on the list.

Right-click on the “Standard SATA AHCI Controller” or any other controller that has “SATA AHCI” in the name.

Note: To verify that you have chosen the correct one, click on the Driver tab -> Driver details. If the iaStorA.sys is on the list, then you have selected correctly.

In the Properties of Standard SATA AHCI Controller, select the Driver tab, and choose “Update Driver…” option.

Next, choose “Browse my computer for driver software” option and then select, “Let me pick from a list of device drivers on my computer“.

Select “Standard SATA AHCI Controller“, click on the “Next” button, and then restart your Windows 10 PC.



I have since changed the drivers back to the automatically selected ones.


Any help would be much appreciated! Thanks.

Those are not the best steps to change from IRST to AHCI mode. I do not see anything in you dumps relating the iaStorA.sys driver though. It seems to point to the following driver: asmtxhci.sys Timestamp: Fri Aug 16 14:28:42 2013.


Create a Restore point before updating drivers.


Update the driver and any other outdated ones from the following link. Let me know if this resolves your issue or not.

Please temporary uninstall Kaspersky as well and use Windows Defender as alternative while troubleshooting.

Kind regards,
