I'm having an issue with my USB 2.0 & Audio ports are not working. But USB 3.0 is working sometimes and sometime not working.
When I Start my PC in my bios screen it shows how many usb devices connected in that screen sometimes it detects my mouse and keyboard plugging in 3.0 usb ports and sometimes not detected. Whenver i try to connect devices into USB 2.0 is completely not working.

So I need a help to how to fix this problem.
