You have a mess! The only hope I can see is a total re-installation of you operating system using the restore partition on the hard drive. Google "factory restore" for your particular make and model instructions.
This will wipe all the data and set your machine back to the day you bought it. After you have successful reinstalled, do all the updates including Windows and a good virus scan like Avast (free). Before transferring your files off the external hard drive, I would scan that drive for viruses with Avast.
Use your dell cd re-install it again. THIS TIME REFORMAT THE C DRIVE BEFORE THE INSTALL BEGINS. This will clear all the folders, retest the drive and record andy bad blocks.
Make sure you choose the FULL format NOT the quick one. See below CUSTOM installation reformatting the hard disk and make sure you do a FULL format.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
