I tried a couple of ways to unlock the shaders on my radeon and i keep on getting the blue screen and my computer reboots.  I used this link and followed the directions but no result.  help.  thanks.

Are you using a reference 6950 with the BIOS selector switch? 

When do you get the BSOD preboot or after you've loaded windows?  Do you have your mining setup to begin immediately upon windows boot?  Did you overclock your card prior to unlocking shaders, and if so what temps were you working with prior to the unlock?

I load windows and try to change bios in windows.  Then it reboots.  The mining was turned off.  My card was overclocked but i dont have a bios selector switch.  Temps were normal.
