Sorry if this has been asked before, but I couldn't find anything that had an answer. I have version 6.4 and my GPU only does 3.30MH/s on ETH. I also can't seem to be able to mine a few currencies or it will make my GPU drivers crash and I have already done a fresh install of the program and my Nvidia drivers. I previously had v5.10 installed when I had my GTX 970 and everything worked fine. My current GTX 1070 has no problems and run all games fine. Can anyone please help me? I also noticed that when uninstalling the program it doesn't remove all the user files and such, anyway to completely remove all of it?
