    In an effort to eek out the best possible graphics Possible Cause 3: benchmark test results, many accelerated graphics cards hog the PCI bus in order to improve their performance. As a result, other hardware in the computer may be starved of bus and/or processor time. When starva- tion becomes bad enough, audio recording and/or playback can not keep up with the data requirements and this results in audible clicks, pops and other audio artifacts.
