I'm running an AMD Radeon HD 6900 Series which is what does most of the heavy lifting for me, I'm only running an I5 processor and only 16 gigs of ram on a Z77A-GD65 Gaming MSI mobo, with a thousand watt power supply. Since I just started this I haven't had a chance to get any hardware specifically dedicated to mining yet, but plan once I understand a little more about the whole process, again, thanks so much for the help!

Hi everyone, Extremely new to this whole bitcoin thing, but it seems interesting and fun, however I seem to be experiencing a few difficulties.

I have my wallet all set up, my miner is running (currently using guiminer for simplicities sake, but I also have cgminer ready to go) and according to my miner I'm mining at about 330 Mhash/s. Here's where my problem arises, while my GPU is currently operating at 99% it doesn't actually seem to be mining anything at all. I simply have a message that says [Shares:0 accepted, 6 stale/invalid]. Now, I'm not quite sure if this normal or not, and I've only been running for about 30 mins, but from what I have gathered thus far, it isn't. I'm sure that the answer to my particular problem is neither hard to solve nor hard to find examples of, I guess all the new jargon I'm trying to learn all at once is just making it a little bit more difficult for me to quickly or easily find. I am connected to Slushs' Pool (I think anyway), any help anyone could offer would be wonderful, thanks in advance.
