I update realtek HD sound driver on a vista 32 bit with driver genius. At first Windows attempted to auto repair wait for that it auto reboot then came up with the KSOD. I've looked around for a solution tried them all but it seems mines different then most. I can't Ctrl+Alt+Delete / Ctrl+shift+Esc for the command prompt, 5x Shift does bring up sticky keys but I don't get a link to the Internet. I also can't run any form of Safe mode / safe mode with command prompt. Also I don't have any form of Vista recovery disc or Vista Media disc. So only way I can fix it seems to be if I fix what causing KSOD.
