Suddenly my PC tells me that no speakers are plugged in (although they are) and I can't get sound although nothing has changed in respect of my setup. Also, and I don't know if this is a coincidence or not, some but not all of my USB have stopped working. Is this a Windows fault or is my motherboard on the way out?
I have no exclamation marks in Device Manager and have tried the driver update route but no success. Anything else I can try that doesn't involve taking the tower apart - I wouldn't have the confidence to tackle anything like that.
