BleepingComputer.com: Wiping computer memory

To access the BIOS you need to press F2 and hold it as the computer is turned on.

I did. It still takes me to the same screen(the BIOS). Then I went to "boot sequence", unchecked "diskette device" as well as "Hard-dick drive c", so it would start up with "IDE cd-rom device". Saved, shut the computer off, restarted, and I still get the message:
"isolunux 4.00 4.00-pre46 etcd copyright © 1994-2010 H Peter Anvin et al reading sectors error(edd)
No default or ui configuration directive found.
That's all it does. Once on that screen, it simply stays there.

Here is what the BIOS screen has, just to make sure I'm entering the right area:

system time
system date

drive configuration
harddisc drive sequence
boot sequence

memory information
cpu information

integrated devices
power management
system security

keyboard numlock: on
Report keyboard errors

Out of those, I enter "boot sequence", and get this screen:

1 diskette drive
2 hard-disk drive c
3 ide cd-rom device
4 bev device(not installed)

I enter ide cd-rom device, uncheck the first two, to start, as i'd mentioned, with the cd-rom, but just get the error message.

By the way? Thanks for putting up with my lack of knowledge, and trying to help anyway

Any other suggestions that I should be trying?
