Ah, I get it. Is there any way to flash or reinstall your bios in 16bit mode by booting from a cd? Why don't you try a bartpe cd and a bios flasher and see if that helps? http://www.nu2.nu/pebuilder/ Just in case you don't know, bartpe makes a windows cd or dvd that allows you to boot directly into 32bit windows. So no installation or any crap, though the whole windows dir is on the cd. It creates a ramdrive, so you should have at leat 256mb ram. And it's a great emergency bootdisk. Or it could be hdd corruption and there are errors reading off it. If it is, you'll have to format again.
