I've spent the last 48 hours trying to get GUIMiner working and searching through threads etc for a fix but NOTHING has worked.

Always worked perfectly well, been mining for several months on Slushs pool with guiminer and HD6950.

I added a second HD 6950 Friday and Continued to Mine perfectly fine. Sometime middle Saturday GUIMiner simply stopped accepting shares. Just stopped. Nothing was changed, updated, turned off, modified, NOTHING. it simply stopped. This is all im getting...

So far I've tried, updating drivers, disabling crossfire mode, uninstalling all drivers and reinstalling 4 different versions of drivers that dated back 2 years... Uninstalling and reinstalling guiminer and bitcoin qt etc etc etc... I've searched and search but no answers anywhere on this. I cant even post on it except for here, Sorry its not the correct section but can anyone PLEASE HELP?  ??? ???

Have you tried CGMiner or Reaper in Debug mode? They're better for giving you a better idea of what the problem is.

Thanks for your reply, Im just not a super technical and was not able to figure out how to get cgminer working :(
Not even sure how to repair in dbug...

You should be using 'stratum.bitcoin.cz' on port: '3333'.

See if that helps.

In the "Extra Flags" portion of GUIMiner, add -D (make sure it is a capital D). Let me know what GUIMiner throws out in the bottom left corner.

This didn't work either  :-[

It is just that specific card? Does the miner work on the other card if you remove that one?

Yeah, if you copied it directly, it wouldn't (sorry, made a typo).

It's : stratum.bitcoin.cz : 3333

It was working perfectly on both cards for a day... Both cards do the same thing. I haven't removed the new card to see if it will run with one card installed. I guess I could try that but still need both to run...

I saw somewhere that it was driver related or crossfire related but neither of those things fixed it...

Where exactly do I try this?

Also, I removed the new card and went back to my old trustworthy configuration with the original card. reinstalled guiminer and having the exact same problem still..  This is NUTS!
