Recently, I did not use my computer for a week or so due to a faulty power plug leading to UPS malfunction. The computer sits in a fairly dusty environment. Once I restarted the computer after cleaning it up a bit, I get this error on start up and no sound from the speakers.
It looks like the on-board sound card has become faulty. Any way of finding out for sure?
May be another dust cleanup for the motherboard will get it back? If not I will have to replace the motherboard.
