repeated OS crashing with uga-2k-a

sony vaio z series laptop running window 7 64 bit keeps crashing and requiring forced reboots when i use plugable usb 2.0 display adapter model uga-2k-a. now my own laptop screen occasionally stutters and i get an error message that states display adapter stopped working and was fixed by windows despite having disconnected the adapter.
