So, before I upgraded from a Vertex 2 to a Vertex 3 HDD, I hadn't been utilizing my mobo's SATA 6G ports so I could just leave the controller disabled to speed up boot times (and because, according to benchmarks, the Vertex 2 couldn't max out Sata3 yet). Anyways, since using the SATA 6G port for my new SSD, I'll come up to my computer only to find it a the black screen informing me that it couldn't boot into Windows. When I rebooted sometimes the Marvell controller screen would appear and the Vertex 3 would just be undetected and sometimes the controller screen wouldn't appear at all. The workaround for this seems to be to restore defaults, which fixed the issue with the Marvell controller, but then I'd need to enter the BIOS a second time to to fix the boot order, since the Vertex would no longer be selected as the boot drive. The only time I've ever seen the actual blue screen, it mentioned a Marvell91 something driver as the issue, but that was after I tried installing the Marvell driver from Asus's website, which didn't seem to fix the issue. After that I did a clean install of Windows and DIDN'T install any Marvell drivers and thus far I haven't actually seen the blue screen, even though yesterday I came to a black bootup screen TWICE. I also tried looking at the event logs but found nothing other than a log saying the system had rebooted unexpectedly (duh). My specs are listed in my sig, and the SATA 6G controller is set to AHCI, although I tried IDE for a while to see if it helped (it didn't). Please let me know if there is any other info that might help. Thanks for any assistance!
