Basically ive had a Creative X-fi Xtreme audio card for about a month, its been working every single day since then, but today when i switched on my pc and tried to play music in media player i got a error message saying something like "you dont have any sound device conneted or it is not functioning" or words to that effect, so i took the side of the case off and pulled the card out gave it abit of a blow and put it back in firmly but still no joy, so i then plugged the card into a different pci slot and its now working? does that mean the other pci slot has broken or something? or maybe a hair or dust has got in there somewhere? i cant think of anything else, the main thing is my card isnt broken and its working right now, but id still like to know whats going on, any ideas?
