I can not start my integrated camera or my external Logitech pro hd. I notice that I have exclamation marks next to USB root hub drives in device manager. I have unistalled the drivers and restarted on many occasions but they are still there. I ma running an Asus laptop on Windows ten. I have tried refreshing, but it wont do it, have also tried reloading windows 10 from a flash drive, it nearly completes and then says there is a problem and the programme will close.. Also can not run windows sys internals. I have run antivirus (Avast) Mbam anti malware, Hitman Pro, but they all pick up nothing.Have updated chipset drivers Etc. Can anyone help me solve this, It would be most appreciated.
