I purchased a set of these (from OC) back in October. At first they worked fine but after a few days I would hear a `click` from the woofer and the system would switch off. After a couple of minutes I could switch back on and restore power only for it to power off again a few minutes later. I contacted Creatve and received a replacement under warranty which again worked fine for a short time but has now developed the same problem. Its as if the system is over heating and a safety system is cutting in. Does anyone else have this system? Has anyone experienced the same problem? My PC is fitted with an ASUS P5K-e wi fi board, Intel quad core duo 2.4Gig and a Razer AC-1 gaming sound card
