If it was me, I would replace the hard drive all together and reinstall Windows on a new hard drive and format the old drive. You will lose everything unless you already had it backed up though. However, if Dell makes has a recovery disc for your computer brand and model, you should order it and give it a try but you will still risk losing everything. Another method is to download a free anti virus program and a disk cleaner for junk files. I use Avast for anti virus and CCleaner (Spelled as it is shown) for junk files. Not sure if these good fixes but it is worth a shot, however, reformatting the HDD and reinstalling the OS are the best choices if you want a long term fix because I know that computer techs use this method all the time. Anyway, I hope this works out for you.
