My acer laptop does not play any sound and camera webcam is also not functioning 
I reset my laptop, yet the problem still persists.
I downloaded realtek audio drivers from their official site and installed , the problem still persisits.
Also , there is no category for "sound video and games controllers" in my drivers manager. 
I have to add it manually every time.

The error message from the drivers 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)"

I have also tried to install drivers using driver easy, yet it was up to no avail.
Please help
