Greetings, all. I use an eMachines series T2862 desktop, and have recently begun to experience a technical difficulty with my audio. The sound shuts off on rare occasions with no explanation. When this happens, the CPU runs at 100% everytime I make an action that would create a sound under normal conditions. It seems as though it's trying to process the sound, but can't. I've attempted procedures that should've fixed the problem if it's either coming from the sound driver or a corrupted Windows XP file. Yet, this continues to happen even after I reloaded the driver and ran the Windows file protection scan. I don't think the problem is coming from a hardware source because the sound always returns after every restart. Has anyone else here experienced the same problem? Could it be a spyware? Would restoring the entire system fix the problem? Thank you for your time.
