I have a audiophile 2496 and I have put it in MANY machines it works fine. Sometimes you have to put it different pci slots to get a different irq. Its a good idea to swap around any cards that are in the machine until the audiophile has its own irq. The card can share a irq and still work fine but sometimes it can cause a issue. Alot of clicks and pops arent cuased by the soundcard but are data path issues. Prob a hard drive issue. Make sure you close all programs that are runing in the background. You should figure out the real issue before you get a new soundcard
