When I "finished" building my computer i installed an older 120 gb hard drive to use until i buy one with more capacity. I have two other drives, a 500gb and a 250 gb one, but whenever i plug them in it causes windows to freeze on boot up. I have also tried turning on my computer and installing windows on the 500 gb hard drive but the installer doesn't even detect that there is a hard drive at all.I posted this question elsewhere and looked on google but i couldn't find any answers. I don't even know where to start trying to fix this and i don't want to buy a 1tb hard drive online just to find out i cant use it. Any ideas at all? Thanks in advance
