Dual displays with 2 C2075s no longer working since Cuda 5.0 install

Hi all,

I have 2 NVIDIA C2075s that both have monitors connected to them. Previously, I have had CUDA 4.0 installed and everything worked great – both monitors worked at full resolution and my home grown cuda code worked fine.

Yesterday, I installed CUDA 5.0 and only one monitor works now and it wont display at full resolution. Upon checking Device Manager under Displays, it shows both my C2075s. I also notice that the NVIDIA control panel no longer works. Even going throught the right-click context menu wont open the program.

Please help – how do I get all this working again?

Thanks in advance,
