ive done this several times but it doesnt seem to be working. ive had a look through several websites but i find it really confusing! help!!

How have you run chkdsk? What exactly did you do? Try it this way:

Open My Computer.
Right click on drive: and select Properties (drive: is any drive)
Click on the Tools tab then the Check now button.
Check the "Automatically fix File System errors" box.

or click on Start then Run, type chkdsk /r and press Enter.

For C: you will get a window that says:

The type of the file system is NTFS.
Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another
process. Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N)

Type Y and press Enter.

Shutdown and reboot. Chkdsk will start. It can take an hour or more to run depending on the size of your hard drive. Be patient and let it complete undisturbed.
