Hi. My sister's PC recently, all was working fine until one day when she couldn't play music. The volume icon on the system tray keeps blinking (mute/mute off with a red icon). She has a sound blaster live sound card, Live Value. I re installed the drivers, same issue. If I try to play music, PC freezes up. The PC was extremely slow, so I re installed XPSP2, all the windows updates, same issue, re installed the original drivers, then the updated drivers, now I get a message that no sound card was detected. Any ideas what might going on? Need a new sound card possibly? Thanks.
