BSOD when computer autolocks, error 1000007e

[flea2005]

Hi, I purchased an HP dvt6-7000 laptop about a month ago - Windows home premium 64 bit. Am using it for work, but recently it's started crashing whenever I leave the computer and it auto-locks. I tried disabling sleep but it still crashes. I called HP support and they had me test the memory and hard drive in Bios, and update the BIOS, but it still crashed.

I've attached the dump files, and also copied and pasted the error code below.

The dumps point to dlkmd.sys, a driver associated with 'WDDM KMD Loader - DisplayLink Core Software'. From the below link, please download the latest version of the program. If the crashes continue, uninstall the program.
DisplayLink: Windows Software
