Upon boot-up I recieving the following message 'Select first boot device' then it gives me the option to boot via the different drives I have (Floppy, DVD-RW, DVD-Rom) it also gives me the option to cancel by pressing 'ESC'. Upon pressing ECS it boots up into windows as per normal. This message appears in a blue box in the centre of the screen with the rest of the screen the black colour. The message appears just after you see all the info regarding your computer on boot-up. I have checked device manager and there is no yellow exclamation marks next to any of the hardware. I have ran Norton Disk Doctor which is reporting no problems. Just recently I have added another case fan connecting it to the power supply directly using the 3-4 pin adaptor. Now I did get this message on the odd ocassion before installing the case fan but it has appeared more often after i've installed the case fan, Conicedence? Does anyone know why this is happening.
