My Dell Dimension 9100 crashed after about two weeks of the sound card malfunctioning. The power button blinks orange. I removed the Creative Labs Model Number SB0410 sound card from the computer. The computer boots up great and works great without sound. I purchased a new card from Dell and installed it. The computer crashed again. Thinking that the new card was faulty, I replaced the card with another new card. The computer crashes again. I changed the PCI slot and the same problem occurs. Help!!!!!
