Was shutting down win 7 pro as normal shutdown when I got the bsod. Stupidly I forgot to write down the error code while trying to get puter unlocked from the bsod. Finally shutdown with off button but when I tried to restart I can not get past the BIOS page that shows mem, drives installed, and basic pre post info; but that's as far as it will go. I have switched ram from slot to slot and tried all 4 sticks I have independently.(ram test shows ok on info page). Rescue disc does not work and have tried booting from a cloned harddrive but only get to the same bios page and no further, so does anyone have any suggestions for me to try. Running amd 2+ black 5000 cpu, gigabyte ga-ma770-ds3 board, 3 gb crucial ram 800, xfx nvedia 8600gt, and 600 watt ps. Any help is greatly appreciated, thanks.
