Have a read through the threads in our Security forum for information on how to detect and remove spyware, trojans, etc.; such an infection could cause the behaviour you're seeing with IE.

Do the IE windows ever stop opening? That is, does the system eventually stabilize enough for you to be able to run other programs?
If so, download Ad Aware, SpyBot Search & Destroy, and HijackThis (download links are in my signature below) on another computer (to avoid having to try to use the problematic IE on your compter), burn the programs to a CD, and install them on your system that way.
