Windows 10: Now i dont have the scan for hardware changes

I am desperately trying to get my camera back. first it came up with a error message. so I came here and someone said to uninstall the camera and restart the computer. I did that and now I cant find the camera icon in device manager. I came back here and asked again. I pretty much got the same reply but they said to go to action and "scan for hardware changes" I don't have that option and now im lost again. I don't get it because other than my firewall which ive since removed I have made zero changes to my computer and my camera was working 2 months ago and now its not. I don't know if there is an automatic update that I don't know about. but I went through the steps if it was updated and still nothing. it said if all else fails call the company that the camera belongs to, but I uninstalled so how am I supposed to know the name of it ?

Must scan device after each startup


I installed a dual serial port card in a PCIe slot in my Acer i7 desktop, Win 10 Home. It works until the computer is restarted, then device manager lists the ports as hidden and says they are not physically connected. If I right click the device and scan for hardware changes, they will work until the next time the machine is shut down and restarted. The manufacturer suggests putting them in a different slot, but that is not helpful as there is only one PCIe slot. Can anyone suggest a way of fixing this or, alternately, is rhere a way to force windows to scan devices for hardware changes at each startup? Thanks for any help.

 

Stuck on "Scan for Hardware Changes"

I was having problems with my wireless network adapter so I uninstalled it on the device manager. Then, I made the Device Manager "Scan for Hardware Changes" so that the network adapter would be installed again, but
every time I tried to scan for the hardware change, the scanning never ended. I forced closed the device manager and tried again but the same thing happened. Every time I pressed "Scan for Hardware Changes" it got stuck saying "scanning plug and play compliant
hardware". I need help fixing this problem because right now I can only have wifi by connecting my computer directly to the router with a cable because I was not able to reinstall the wireless network adapter.

 

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)
