I have been seeing some strange bios behavior lately. When I first turn on my computer sometimes right after POST I see bios image logo freeze with lots of colors that are distorted. Also sometimes when I click restart computer it just hangs and doesn't reboot my computer. When in bios menu I see the letters and the [ ] around the letters blink really fast. This all started when I upgraded my graphics card from my old 7800GTX to my new 8800GTX, might this be why all this is happenning?
