Look for the file below and if there...:
C:/Windows/system32/wdmaud.sys
Delete it (or move/rename) and Reboot.

Next,
1.click start-->run-->devmgmt.msc-->ok
2.on the device manager, click view-->select show hidden devices/drivers.
3. then click on "non plug and play drivers/devices", and find TDssserv.sys
4. right click it, then select disable, then restart the computer.
5. then check if the problem still persists. good luck!
After doing so!
