What happens if your computer is visited by gremlins at work? you phone your I.T support department and they asks you a few questions you say something like "i have no idea, can you fix it? i need a coffee anyway." when you come back to your desk, you have no idea what happened nor do you really care, whats important is everything works again.  

however, when your at home what happens ? the gremlins turn up for a party in your PC you get frustrated and who do you call? 

scenario 1. a family member or a friend that works on computers comes over (eventually) and in between huffing and puffing they click on things so fast, even if you had any inclination to understand whats going on you have no chance of knowing what happened. 

scenario 2. you go to your local pc world and they charge you £40 for the privilege of looking at your computer then telling you "is broken" this of course you know. then comes the news that it will cost the same as a new pc to fix. so, what do you do? 

New Scenario. you phone the local geek, your problem is more often than not diagnosed over the phone. we let you know that we have a flat rate cost for labour and give you an idea of how long it will take. everything works again.
