cgminer problems

[yomamanodros]

I have been successfully mining litecoin using cgminer for about two weeks without any problems.  In the past few days I have had far more rejects than normal and cgminer fails after running for about 5 minutes.  The accepts just start to slow down and then stop completely followed soon after by the program crashing completely.  This problem started around the same time I changed pools so I thought it might have been that, but now cgminer crashes when I use my original pool as well.

The accepted shares seem to usually stop coming right after stratum detects a new block.

I have tried installing the newest version of cgminer but that didn't do anything.

I have 3 Sapphire radeon hd 7950's running on windows 7.  

Does anyone have any suggestions on what this issue might be?

Whats your configurations?  Whats your drivers version? Most crashes I usually see is due to temps getting to high.

Yeah, more info.  What temps are they running at and what does your config or batch file look like?
