Thank you for reply.
I've downloaded all relevant Drivers
for ASUS Maximus II Formula from ASUSTek Computer Inc as you suggested. In Utilities I installed "AsusUpdt_V71706", Installed the latest "soundMAXAD1988B_Adio_V610X6585_Win7", and lastly installed "SB_XFi_V10_R19_XpVistaWin7" and updated it. After restarting windows I am still having issue with it. Will that help if I reinstall Windows 7 and start all over again this mean I have to reset my RAID ARRAY again but I fear that I may get the repeated problem...Is there any other way around this problem.Thanks again
