My computer has had a bit of a problem lately. After powering on it becomes especially slow, and then I formatted it the usual way and got ready to reinstall. At first everything seemed to go smoothly, but when it got to the self-check it showed that drive C had a problem (I don't know what went wrong either), and then it told me to fix drive C first before installing Windows. But my C drive has nothing on it right now. I don't know whether it can be repaired under DOS. If it can, please tell me the repair command and how to use it. I would be extremely grateful! Thanks, everyone.
