What OS are you on? If it's 10, it's likely windows has installed the driver it thinks you need (which might be older, or BETA) that's causing the conflict.
You can turn off the hardware driver auto-updates (http://www.tomshardware.com/faq/id-2763685/stop-windows-automatically-updating-device-drivers.html) but then the onus is on you to update it thereafter.
