Fix: KMODE_Exception_Not_Handled (mv91xx.sys)

Most of the users that have (and are) experiencing this issue have Windows 7/10 operating systems installed on their computers. The root cause of this problem is the conflicts that are arising between some of your system drivers and the Marvell 9123 Disk Controller. The drivers that you might be running on your computer might be obsolete or just plain incompatible. But probably you already know the problem but don’t know where to find the latest drivers? Is your supplier’s website unable to give you the driver that will lead to the end of your worries? Then you have ended at the right place.

We will share a trusted third-party website from where you can download the latest drivers and install them on your computer to rid yourself completely of the mv911xx.sys caused BSODs. Perform the following steps:

If your download doesn’t start automatically, click on the download button once.
