First of all calm down and be relax.

It's not the wallet that is the problem, it's the computer itself, it won't turn on.
calm down , it is a silly problem.
You can get back your data easily , what type of PC you use old(serial cable one) or compact type(New Type)?
You can take out your hard disk and switch it in other cpu and then try copying the wallet data from that hard disk and then save it in new PC , and your problem is solved.
