Hello Steve,
Lets start at the very beginning. Is your eMachines computer a laptop or a desktop computer?
Also, to be clear, you already own a valid Product Key, correct? This is a sticker on the bottom of your laptop, or on the rear or side of your computer, and clearly is marked Product Key. I want to make sure you can read a DVD OK - do you have a DVD that
you can test in your machine?
Lastly, are you downloading and making the copies of the ISO files on the "damaged" computer? If so, we may be able to salvage your computer another way. If the answer to this question is yes, try this instead of the Windows DVD: download and burn to a
CD the following: http://download.cnet.com/BootMed-64Bit/3000-2094_4-75450831.html .
You do this by downloading the file (another long download) and then right-clicking the ISO file, and then clicking on Burn to disc (this will fit on a single data CD).
If you can do this successfully, insert this CD into your computer and try to start it using this CD. Its a Live CD that should allow you to boot 'around' any virus or malware infection, and allow you to restore your computer this way.
Please let me know how you want to proceed and/or answer my questions and we'll move onto the next step.
Regards,
BearPup
P.S. Don't worry about the time it takes to work through this, I just want to make sure you get what you need. I'm happy to help you.
