Yes, i do know this is an ati forum, but i was wondering if one of the few nvidia people out there could help me. I've been using AtiTool for most of my overclocking needs since i got my 7900gt. Recently though, AtiTool has stopped working. It cannot detect my card, read temps off of it, or anything. Although under settings -> use device, its set to Nvidia 7900gt. Also, a lot of other applications cannot pull gpu data anymore. For example, Everest Home no longer has any idea as to which graphics card i am using. Is this something to be worried about?
