When i went to device manager three of my Standard Enhanced PCI to USB Host Controller has yellow exclamation signs and when i click on device status it says this “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)” It wont recognize anything i put in the USB ports and the built in webcam wont work either and the only that works is the touch pad mouse. When I try to update the driver it says its already updated
