Default [Q] Galaxy nexus wont boot

Hello ,

yesterday my troubles with my Gnex started , my power button stopped responding (only a small percentage of times it worked) which meant unlocking/locking my phone was hard. Today the problems got worst I am not able to start my phone at all anymore. I've tried multiple solutions shown on the internet for example the solution of taking out the battery , plugging my phone into my pc and then putting in the battery and turning it on.

Does anyone have any solutions to this problem.

Hope someone can help me ,
Thanks in advance Dendroo
