Can't write to C drive

[bobbster2000]

Whenever I turn on my pc, I get a message saying "Can't write to drive C, may have bad sectors or files may be missing." It then does a scan disk and doesn't come up with any errors. Then, when windows opens up, as soon as I touch my mouse or any key on the keyboard, the screen turns blue. It tells me that "Can't write to C drive, may have bad sectors or missing files. Do a through scan disk."
I've done the through scan disk over and over again but it never finds any errors. Now when I turn on my pc it automatically opens up in safe mode and still gives me the same error messages. Can any one please advise me on what I can do to restore my computer?

How much free space on the drive? Can you get into dos and delete any temporary files to make more free? This is the first check. Ed Fair
