Have you got your wallet.dat backup?

Here's a step by step guide

Yes it will - it will generate a new wallet.dat
Don't understand the question
Info about transactions is stored in the blockchain(blk0001.dat, blkindex.dat) not in the wallet.dat. wallet.dat contains your pub/priv keys

You may want to familiarize yourself with how Bitcoin works by reading our wiki

Also, you definitely want to read about securing your wallet

If it is not obvious and you are completely brain dead, this post is for you
DON'T BUY OR TAKE ACCOUNT FROM A STRANGER!!!

Back up your wallet.dat before updating. It should be fine, but backups never hurt. Then download new client, uninstall the old one and install the new one. That's it.

Btw, geeks ARE normal people - the rest of you are a bit weird

Post the exact figures at this moment

That's exactly the one my friend blew in two hours, except it was 1050W  Don't buy PowerCool

 

Like phantastisch said - it totally depends on the brand. The amount of power you have is plenty. I was mining on a 5870 with a 250W for about a week until I got round to buying a better one while my friend blew a 1000W brandless psu within couple of hours mining with 2x 5870

So you think CIA has something that is faster than the top 500 supercomputers on earth combined?
