PC hardware--CPU & Motherboard & RAM/peripherals
There seems to be a problem with all the USB peripherals ( webcam,printer, scanner Bluetooth etc ) on my desktop.
When I checked the device manager these devices have a yellow triangle with error code 39 (see attachment)
I tried re installing the drivers but it did not rectify the problem
Can you identify what or where the problem may be?
Most likely the problem may be in updating the system components. Give it a try on the motherboard (or computer) manufacturer's website, and look for chipset drivers. You might also find BIOS updates may be needed.
Updating those components is not difficult but requires careful attenton and understanding of what you are doing, because it may brick your motherboard.
