No, I haven't checked it in disk management yet. when I didn't show up in windows I just came to the library, to start loooking up how to solve the problem

.
Nope, didn't test the old drive. It didnt' come with a diagnostic utility. How do I test it?
and I'm not sure what kind of crash it had either. It just stopped working suddenly. one day I went to turn on my computer, and it wouldn't load windows. It would just go to a blue screen, then the blue screen would disappeaer too quickly for me to read what was on it, then It'd go to a screen that told me windows didn't load properly, and asked me if i wanted to boot into safe mode. but even when I'd do that, it'd just repeat the process over again. I took it to a repair place, and they told me the hard drive failed, so i just got a new one and now i'm trying to figure out if I can save my old files.
