I find out my main dual gpu rig went BSOD on me Dec 24th... reboot and ... disk I/O error not good. BIOS is reporting this is a S.M.A.R.T. drive but not responding to commands, and the rescue disk sees the drive sometimes and not others.
So I have actually managed to get the system booted again (typing from it now). I have ordered a replacement hard drive and am taking a system image backup now. If I make it through this successfully I will be surely surprised. Friday the drive gets here.
