If you don't want to run that, it's ok. When you get your disk from Dell come back here and somebody will help walk you through your reformat and reinstall. Now anything you have saved on there, documents, music, pictures and the like that you want to keep you need to back up to a cd or flash drive. Take note of all the programs you have installed, you will need to reinstall all of those also. Go to the Dell website and you should be able to log in there and get the full specs of the computer as it was when it was shipped to you. This should tell you drivers, etc.
You might do a Belarc scan and print that out also. This will tell you what all is on there now so you will know all you need once the reformat/reinstall is complete.
Can't think of anything else, maybe cauz can think of something else you will need to do.
Once you get the disk just come back and we will get you started. Should take a couple hours to reformat and reload. Then add drivers and do the updates needed. After that you can put your programs back on.
