If you’re seeing a yellow exclamation mark next to your PCI encryption/decryption controller in the Device Manager, you’re not alone. It indicates something is wrong with the driver for this device, but you can resolve the trouble easily.

Here’re three ways to update the driver for your PCI encryption/decryption controller; just pick one to your liking.

  1. Update the driver via Device Manager
  2. Update the driver automatically (recommended)
  3. Download and install the driver from the manufacturer

Option 1 – Update the driver via Device Manager

One easy way to update the PCI encryption/decryption controller driver is using the Windows Device Manager. You can follow the steps below to do it.

1) Type device manager in the search box and click Device Manager.

2) Double-click Other devices (or Unknown devices) to expand the list.

3) Right-click PCI Encryption/Decryption Controller, and click Update driver.

4) Click Search automatically for updated driver software.

Windows will directly download and install the detected new updates. Then, reboot your computer to fully implement the change. If Windows fails to find the driver for your PCI encryption/decryption controller, try the next method below.


Option 2 – Update the driver automatically (recommended)

If you don’t have the time, patience or skills to update your PCI encryption/decryption controller driver manually, let Driver Easy do all the job for you.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing.

All the drivers on Driver Easy come straight from the manufacturer.

You can update your driver automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 steps (and you get full support and a 30-day money back guarantee):

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click Update next to the flagged device driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the Free version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

You can do it for free if you like, but it’s partly manual.
The Pro version of Driver Easy comes with full technical support.
If you need assistance, please contact Driver Easy’s support team at support@drivereasy.com.

If you want to update the driver on your own instead of using a driver updater, check out the third way.


Option 3 – Download and install the driver from the manufacturer

You can manually install the latest chipset driver to solve your PCI encryption/decryption controller driver issues. This may take some time for searching and downloading. First off, you need to go to the manufacturers’ websites:

Then, find and download the right chipset driver corresponding with your specific flavor of Windows version (for example, Windows 32 bit) and download the driver manually.

Once you’ve downloaded the correct driver for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver.
