The system can not sound (Come help me rookie!)

Users questions: The following issues when playing music; I uninstalled the sound card after (RealtekHighDefintionAudio), and then install the sound card. Sound can be heard, but after restart the same problem occurs. I scan with Kaspersky 7.0 N films, there should be no viruses. 7777 77 uninstall sound card, and then re-install the motherboard drivers, install the sound card driver.
