Eraser Forum

OK...I'm a complete moron when it comes to this terminology! I THINK I successfully burned a CD with the DBAN program. But now I get the error rundll32.exe missing to run DBAN.
Is it possibly b/c I ran eraser earlier today and it was erased?!?!?!

All I want to do is erase all my files on my hard drive b/c we're donating the computer.

Please help!
