So I have a 460GTX it is not overclocked yesterday it hit 66Celsius. I've had it hit 70 in the past with no issues. But after last night I don't know what the deal is but I'm getting weird like hm. They look like giant spikes. They come from textures in almost all my games. I've seen rainbow colors on specific objects. like Doors Or signs. I've had flickering textures and things go black. Temp is down now running at a steady 50C and still getting weird errors. Is the card fried or is this some type of driver error? I've had issues with my graphical driver for a long time.
