2 cards working fine, but third card is stuck at "Starting"

[iamzill]

I'm running three 5830s on a MSI 890FXA-GD70 motherboard. I'm running XP SP3. Two of my machines have this exact same setup and they're experiencing the same error: after clicking "Start mining" in the GUIminer, the lower right hand corner status bar is stuck at "Starting...".

No hash rate, 0 shares accepted forever, and MSI Afterburner is showing 0% GPU usage for that card.

Thanks in advance.

I tried both Slush's pool and BTC guild and have the same problem.

If I use the summary or the console it'll say "Connecting..." forever.

After I click "Start mining", in the console it'll display "Listener for "Default" started" and then nothing happens for 5 minutes. 5 minutes later the line "long poll: new block 00000xxxxxxxxxx" will come up, but still no hash rate or GPU usage.

Is this a network problem or a card problem? Should I swap out the cards and try them on different machines?

I've had to convert my friends from mining on Windows XP to Windows 7.  7 handles multiple video cards 1,000 times better.  I have one friend who has tried everything in the book, yet one of his cards never hits a solid 99% GPU usage, it fluctuates everywhere.  I'm betting him 7 will fix the problem.  The overall layout of the operating system is different when it comes to handling the video drivers.

Thanks, I'll give Windows 7 a try.

I used XP because I have many licenses for it.
