A few days ago my BIOS screwed up. It took a very long time to test my memory and it didnt detect my cd-roms/floppy drive. And it said that my memory speed was DDR200 and it really is DDR266. The boot sequence was also all screwed up and nobody was on my computer. I cleared the BIOS and had to reinstall Windows. My computer works fine now , but I am just curious what happened! Does anyone know what could have gone wrong?
