Put your GPU back to default clock speeds... unfortunately i have no idea how to do this with GPU... try resetting cmos jumper and battery, might work, other then that i have no idea...
Actually use onboard video to get in, and reset settings there

Can we get a photo of the thing you mean by dot dot? If you can get into rivatuner, put the GPU back to stock speeds
