A BSOD thankfully is different than a Post Failure**. In the BIOS Load Optimized Defaults, save and boot. If that fails then Clear CMOS (Button or Jumper method); see -> http://www.youtube.com/watch?v=rdHH9KrceR0
Now if both of those fail then boot off your Windows DVD, assuming Win 7, press F8 use Startup Repair -> http://windows.microsoft.com/en-US/windows7/What-are-the-system-recovery-options-in-Windows-7
and if needed System Restore.
Once, hopefully, in Window you may have a mix-match BIOS to Windows -- e.g. BIOS SATA -> IDE <=> Windows Start -> 0; the correct choices are SATA -> IDE <=> Start -> 3 <or> SATA -> AHCI <=> Start -> 0; see -> http://support.microsoft.com/kb/922976
use 'Fix It' or manually match-up BIOS and the Registry.
**Often when updating the BIOS if you set SATA -> AHCI then updated the BIOS the setting changes to SATA -> IDE and you end up with a BSOD at startup.
