Can’t Boot In Safe Mode

I got the dreaded blue screen of death. I have reformatted my HD and installed a new video card. I also can’t boot in safemode, safemode w/networking, safemode w/command prompt, or any opitions the menu offers. I get a keyboard error everytime I initially start my computer even though my keyboard still works and so do other keyboards that i have used. I also cant see the monitor when i plug it into the tower, but when i plug it into the new video card slot it works. Im fresh out of ideas so any information would be appretiated. Thanks
