When my computer is running an application or for that matter simply running, distictive tickticktickticktick in the background can be heard. It is faint but drives me crazy. Could it be a problem with the voltage, or maybe the harddrive? I am running on an antec neopower 480 watt power supply, powering 2 GB ram, fatal1ty sli, 7800gtx, xfi sound. Maybe other people are running into this problem?
