Hey there,

I'm totaly new at the whole mining thing. I considered it once, but it did not seem very    
lucrative. I now read comments from 2 years ago saying a newcomer tried it out and made 10 BTC in a couple of days.
Well... fuck me for not jumping on board then cause with the prices going trough the roof.

So I decided to try it out now, maybe with the high-value of BTC's I might even make some money.
I've set up my wallet, GUIMiner and deepbit and everything seems to be worken, but.....

There are a couple of things that seem to slow my speed down from +-300 Mhash/s to only 300 Khash/s.
The decrease is usually when i get the messages:

 "long poll: new block...."
and

ADL_Adapter_ID_Get failed, cutoff temperature disabled for 0:0:Pitcairn

I don't know why my speed drops after a new block has been found but it does, and when I stop/start for a sec it will be back to normal.
I don't even begin to grasp what the whole ADL Adapter thingy might mean. Can it be my PSU isn't sufficient anough?

Any help and or advise would be much appreciated.
DeepBit has pulled me true the start up, I hope you guys can help me get rid of the little problems aswell;)
