Has anyone ever had a problem booting their computer and tried everything imaginable only to find out it was trying to boot from a USB device? I couldn't get mine to start, so I took out all my cards, reset the CMOS settings, unplugged all the electrical stuff. Still couldn't get it to boot. I'd forgotten that newer BIOS's allow booting from USB devices. So, I unplugged all the USB devices and it started fine. I forgot to turn off the "Boot from other device" option. Has anyone else ever went through this ?
