PC distraction

I don't have a full answer for this question, but partial. I'm really looking forward to see more answers.

1. Don't install IM client on your PC. It's a productivity waister.

2. Dedicate 1 hour every day in your schedule for personal work on your PC.

3. Open Outlook only 2 times every day (this advice is by the happiness guru, ben-shachar).

Procrastination is when you successfully find every excuse not to do the job at hand. There is no tool of which I am aware that will force you to concentrate on your task. You must develop self-discipline which is not easy but you can find a way to do it in a positive manner by giving yourself a compliment each time you prevent procrastination from interfering. You could even go out and buy a present for yourself if you complete the job on time. E-mail can be a time waster. Just as a manager gives himself one hour in the morning to go through his mail you should do the same and not devote any additional time. You will see that most e-mail do not require immediate attention. But again there is no substitute for self-discipline. That's how academics, novelists, etc. get their work done. 

Repeadidly remind yourself that you have a specific task at hand to do.  Once that task is completed, (for example, homework or research) then, and only then, you can move on to something else, such as playing your favorite computer game.  At first, this will take a lot of self-disapline, but it really works!  It will help you a lot with your time management skills too.  We all can get distracted so easily, but you have to learn to disipline yourself and your mind at the task at hand.  Practice concentrating harder on what you are doing at the moment and don't let yourself get "so distracted" by everything else you see and hear around you - even while working on the computer - Sort of being more "mindful" by trying to stay in the moment.  Pretend that you are in a library in a quiet area, and you have a lot of important reasearch to do and have to take notes, as well.  You certainly wouldn't want everyone bothering you, now would you?  You can always minimize a program and return to it at a later time.  If your tempted to download something, book mark the site or put it into your favorite places and return to it at a more convenient time.  Hope ths helps.
