Newbie here. This is my 1st post, and I just learned of the existance of BitCoins 2 days ago.  I make enough cash from a real-world job to invest in hardware, and I am eager, but I am reading mixed opinions whether it's even worth it or not.  Plus, I want to try and get it to work on my existing hardware before buying anything.  I've already opened a BitCoin wallet, registered on Slush's pool, and tried to use GUIMiner on Slush's Pool.  But, my GUIMiner just sitts there and says "starting..." without actually doing anything. It did this for 16 hours.  Yes my Slush login info was entered, yes it works on their website. Hopefully an advanced or intermediate user can tell me why my miner won't mine...
