Sata Ahci Controller Driver Windows 10 Dpc Watchdog Violation

Some Windows 10 users have been reporting that they occasionally receive a DPC_WATCHDOG_VIOLATION Blue Screen, with a Bug Check code of 0x00000133, when working on their computer.

In Windows, many of the errors that trigger DPC Watchdog violation, are caused by SSD drivers, even with some quite recent ones. Its necessary to update the firmware on the manufacturer’s website. The firmware is the device’s own instructions that control its operation, they aren’t drivers that are installed in Windows. To fix Windows 10 DPC Watchdog Violation errors, try this: Right click the Windows Start button and select Device Manager. Open the IDE ATA/ATAPI controllers section and select ‘SATA AHCI’. Right click SATA AHCI and select Properties. Select the Driver tab and Driver Details. The correct driver is ‘iastor.sys’. If it is, continue to Step 5.

Apparently, this issue occurs because the iastor.sys driver, is not compatible with Windows 10. Microsoft is aware of this problem and is currently investigating ways to solve this issue, by preventing the driver from being migrated when upgrading to Windows 10.
