So i've owned this strat for about a year and it has been pretty good, but all of a sudden today i pulled it out of its case to play it and the strings wouldnt vibrate when i hit them.

After examining it i realized when i pushed the strings down on the guitar they hit the pickups causing the string not to vibrate. I've tried tightening the screws around the pickups and its not working. How can i fix this because im getting very frustrated? thanks.
1. try and lower the pickups as far as possible
2. raise the string height
3. take to a professonial
Yea ive tried doing that. i have a guitar lesson tommorow so ill see what my teacher can do and if he cant fix it ill just leave it at the shop and see what they can do with it.
