help..vista will not recog Raid today?

Vista will not recognize my raid this morning. It shows in BIOS, cannot get vista to see it. Computer managment is not showing it.

I rebooted many times, restored back before the last windows undate a few days ago. Of course I never can restore vista w/o errors doing so. Any ideas?
