Yes, it is possible. Reinstalling will just replace missing system files and won't repair a damaged registry. However, as long as you do it over-top of your existing installation, you won't lose anything. So it doesn't hurt to try.
However, it seems as if your system is infected with either a virus or some form of spyware that's hanging your system. If you have a large enough hard drive, you might be better off creating a second partition, copying over as much as you can to it, then formatting the primary one and doing a clean install of Windows. Then you can just restore all critical files and documents from the copy you made. Of course doing it this way can take some time, considering you will STILL have to reinstall your applications, but at least you get a fresh start. Utilities like Partition Magic ($19.99 or less) can help you with this.
In the future, backup your system regularly. If you have a CD or DVD Burner, create an image to disc using a program like DriveImage or Norton's Ghost. It will save you a lot of time in the long run. Plus, you never know when your hard drive might croak.
