Hi everybody. I just bought myself a Powercolor Radeon HD 4890 yesterday. After installing the card and the required drivers everything works like a charm. However, every time I start up my PC I get a message saying that a new device has been found on my system. On checking Device Manager I found an "Unknown device" entry under "Other devices". I'm attaching a screenshot of Device Manager. Are there any drivers I'm missing? It only happened after removing my old card (after uninstalling all its drivers) and installing the Radeon. Any help is greatly appreciated. Thanks.
