Ilan,
You are NOT a piece of damaged good. You posssess a heilige neshama, a TRUE nefesh Eloka Mimaal, a soul that is part of G-D above. Even if for some reason (yes, we make crazy decisions
) you feel like this, perhaps it is better not put it in writing.
If I could humbly share the following (even if it does not make sense), as this has worked for me:
If I were in your situation (and I recently was) I would, for the next couple of weeks, forget about the computer problem. Instead, I would just focus on my shemiras einayim in the street. By this, I mean being DEAD SERIOUS about not looking, with the exception of first blood relatives at ANY and ALL women in the street. Without going crazy (hey, if someone crosses in front of me that's how it goes, but I avert my eyes from her face and body), do not look and turn away from any femenine creatures. This includes any "parve" magazines, any and all movies, TV, news anchors, newspapers, Yahoo's homepage), store clerks. If I were in a college your situation (as I think you are) is indeed difficult but not impossible if I really wanted and exerted myself.
I spoke once with Elya and his advise was priceless. I would strongly suggest that you speak to him, as you said, before Shavuos.
With best wishes for a kabalas haTorah beSimcha u'BePnymius.
YosefYakov
WE ARE WITH YOU
