PLEASE HELP. MALWARE HAS TAKEN OVER MY COMPUTER

HI, I have a dell inspiron 1721 laptop and have been having so much trouble with it lately. It is so bad that I can't even log onto my computer normally anymore. I can only use it when in safe mode. When I try to start it up normally, either the feared Blue Screen of Death comes up and it keeps restarting. If I don't get the blue screen of death, and it actually starts up normally, then Desktop Defender 2010 pops up which I know is a malware infection. I am desperate at this point and I don't have enough money to take it into a computer place and get it fixed. This has made my life more difficult then needed as a student, where I am now spending more time at the library using computers rather than just being able to use my own. I don't know if this will help at all, but these problems started occurring shortly after I installed a WD smartware external hard drive. If anyone has any information on how I can fix these problems I would greatly appreciate it. I would just like to be able to use my computer normally and all of the programs that are on it again. One final note, since I can only run in safe mode, I have tried to install many suggested programs unsuccessfully because the Windows installer will not work in safe mode. PLEASE PLEASE PLEASE respond to this if you think you might know what I can do to fix my computer
