I upgraded to windows 10 July 29th. Since I installed windows 10, 3 drivers have been giving me error messages:

 

1. HL-DT-ST DVD + - RW GHA2N SCSI CD ROM Device
2. Logitech unifying usb receiver (came with dell wireless keyboard and mouse, both of which work)
3. Dell Wireless 1703 802.11b/g/n (2.4 GHz) (wireless printing works, as does Bluetooth)

The error message is:

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

 

Steps I have taken:

1. Installed driver for Dell wireless card from Dell website, Install repaired the previous install but did not correct the issue
2. Attemped to click on Update driver, which returned the message the driver is up to date
3. Clicked PC checkup In Dell support assistant, and ran Dell diagnostics from the dell website, both of which failed to identify the malfunctioning hardware, and came back “passed”
