Yes i try to add new hardware, and reinstall too. Windows see the hardware,and said the driver is the newest, but can't use. "Code 39."

The website mentioned above should solve  your problem, do be careful to exactly do what it says because if you make a mistake in your registry, the result won't be nice  ONLY do what it tells you to do.
