So I recently upgraded my motherboard, processor and ram. When I go to post though the most I can do is get into the BIOS. I keep getting an error for "system thread exception not handled" when I try to get windows up and running. I'm aware it's tied to display drivers since I'm using the same GPU's from my last setup. I just can't get it into safe mode so I can uninstall/ re install my drivers. Where do I go from here?
