My brother had a Dell computer and wanted to upgrade video card but he have a btx case with 4 1/2 " ( hard to put a 8800gts in there )So i decided to get a new board with a new cpu but keeping the hard drive. Now i installed all doesn't want to boot into vista blue screen pop up and too fast to read anything. I wanted to go into Boot safe mode but there not even a boot safe option just BOot Normal and Boot diagnostic too that search for error and (try) to fix it. So i guess need to reformat or there a way to get really in safe boot mode ?
