Disk write error

[jennifer]

For the past two days my computer keeps saying

'Disk write error
Unable to write to disk in drive C:
Data or files may be lost
press any key to continue'

When I reboot it says that I need to run scandisk to repair any problems on the disk. Scandisk does not help and it does not find any errors, even when I scan thoroughly.

I cannot figure it out

How did you make this problem occur?

I don't know how the problem occured. The night before it was fine and then the next day I turned the computer on it was saying disk write error

Attempt to start your computer using a bootdisk.
