2x Nvidia Geforce 560gtx SE SLI

I have been runnings games at ultra settings with high fps and then suddenly one day the performance drops dramatically to 5-10 fps for any game even at low settings. I ran msi after burner and ran diablo 3. The results were average cpu usage 50% while gpu 1 runs at 99% and gpu 2 runs at 10-15 %

Im not very experienced with sli would appreciate some feedback

P.S. I bought both cards about 2 weeks ago, but I didnt install sli till the second week because I had to wait for the sli bridge to come in the mail.
