ddkmd.sys blue screen in Windows 10 start up


Bought a $9 USB 3.0 to VGA adapter from eBay and thought it is a straightforward step just to install the drivers (from the CD) to my Windows 10 PC. After the driver installation, it asked to reboot the PC. Then, the PC got BSOD (Blue Screen of Death) with ddkmd.sys exception. The PC tried to repair itself and reboot again. The ddkmd.sys exception blue screen keeps coming after the reboot.


The standard solution is to remove the new installed failed driver and stay there.
Since I'm a long time IT veteran and I believe there is no problem can't be resolved. So, I downloaded a suggested windows 10 driver from http://osbase.com/idisplay/. Luckily, it works.

A. Remove the failed driver
To remove the failed driver, Press F8 to boot into Windows 10 restore option while in PC boot up. Choose the option to "Restore from a system restore point". Follow the on screen direction to restore the system state before the failed driver. At the end, there is a reboot. It should bring your machine back to normal.

B. Download and install a proper display card Windows 10 driver.
If you are brave enough like me, you can download and install the driver from http://osbase.com/idisplay/. The one I downloaded is http://osbase.com/Drivers/151219CL2534iDisplaySetup.exe.

Or you can contact your seller or someone know the right driver to install it. After the proper driver installation, the proper driver should show the new display device in device manager. In my case, it is "Fresco Logic FL2000 USB Display".


Good luck to you.


Paloma tankless water heater C4 56 error

Couples days ago, my Paloma tankless water heater got the C4 56 flashing error code. Hot water never comes out from the faucet anymore. I searched the web and found no solution to the Paloma tankless C4 56 flashing error code issue. So, I tried to resolve it by myself.

The solution is: Restart the water heater.

How? Unplug the power plug and wait 5 seconds. Plug it back.

Then, the water heater is up and running again.

This is not cool that the cause is not found yet. It is good that it buys me sometime to find another solution or shop another one. Yay!

Hope this solution works for you too. If it works for you, please leave a comment. :)
