my sound card

i have a sound blaster audigy SE 24 bit sound card. And i within the past few weeks got a new case and transferred everything. But i lost my driver disc and it took me a little bit to find the drivers i needed. But i got them and it worked..kinda. It worked for about a week then it just stopped. then it started working again without reason. i didn't change anything, it just started working two days later. But not it has done the same thing. I don't know if it's a driver error what. Any ideas. thanks in advance

 

I think i would try reinstalling the card, sometimes just removing and reinstalling cleans the contact area enough to clear up problems. ed
