I put in a new motherboard and cpu, the HDD stayed the same with my old windows 7 on it. Trying to start windows would lead to a bluescreen so i decided to reinstall it. BTW this same harddrive works with another computer, everything turns on. So the problem with reinstalling is that i keep getting an error that says that "The file or directory D:\Documents and Settings is corrupt and unreadable. Please run the Chkdsk utility. How do i do that? I ran the Cmd and in it ran Chkdsk D: and later Chkdsk f/ D: but all i got was a message saying "Failed to transfer logged messages to the event log with status 50"
