Hi everyone! 1st, i'm from Poland, so my english isn't perfect. 2nd, yesterday i get on my computer Windows 7 Professional. It work's fine, but i don't have sound. Windows 7 atomatically installed some drivers but they don't work. Then i installed another from my motherboard site for win7. But i still don't have sound. My motherboard is Gigabyte M57SLI-S4. Could someone help me please?
