A bad block is a problem which might indicate the drive is going bad. How old is the drive and is it still under warranty?

Let's have a look:

Copy this command to your clipboard:

When the prompt appears Right click in the window and click paste on the menu.
Press enter.

Do the same again using this command.
Copy this command to your clipboard:

Press enter.

Restart and allow it to run.
When you get back, go to Start >Run and type
Eventvwr.msc
Press enter
Double click on Application in the left pane.
Look in the right pane for an item whose source says winlogon.
Double click on that to get the report chkdsk created.
What does it say?
If you want to copy it, look at the icon which looks like two pages and click on it.
That copies it to your clipboard. Paste that in here.

If it were me, after finishing all this, I would back up any files on that drive to CD if possible so they weren't lost in the event of a hard drive failure.
Then we'll continue. I'll look closer at your events files after we determine the state of your drive.
