Asus F2A85-M Pro with RAID-1 configuration running Windows 7 Pro 64-bit SP1. Computer has been working flawlessly until this weeks Windows updates. Now it boots to Windows with several corrupt file messages and fails to login with more errors. Cannot open Task Manager at any point. Pulled both drives and Scanned for viruses = Clean with Malwarebytes and Norton full scans. TDSSKiller nothing found either. Boot to Safe mode is not successful. Ran the chkdsk /r an it repaired hundreds of errors. Still no change. Attempt to run system repair I am stuck at loading drivers. Running system repair from RAID-1 or DVD. RAID controller is an AMD chipset onboard the motherboard. Downloaded all available versions from Asus website, but W7-64 drivers always come back as drivers do not belong to this hardware? I have also tested both drives with WD lifeguard extended tests = OK! I do have a backup image from before the Windows updates I will use if all else fails. Want to understand what caused and why before this is a recurring issue.
