2. The simplest solution is that we right-click the exclamation mark, and then click "Update Driver" in the pop-up to see if this can be resolved without, if we can't solve our downward view.
3. We first go to Baidu search to download a "Universal Driver assistant" and then open it.
4. Then want to not recognize the hardware, open the chassis, the optical drive to connect the data cable unplugged, and then changed the interface, the boot detection, or did not find, this is going on, my head is big.
5. Try adding hardware to the Control Panel. Follow the prompts to do it step by step. What I see here is the optical drive with an exclamation point. But it's okay to see an important message here, "because of incomplete or corrupted configuration information"
