Zoness,
If your not dead set on Boinc there is a project that we run called Wieferich@Home that has fairly long wu's (8 to 10 hours with your machine) and uses very little bandwidth as it only uses your connection upon compleation of a wu. You can give it a look if you want and just holler if you have any questions. the url is www.elmath.org But, no matter what you want to do welcome to the forum and remember to at all times HAVE FUN!
