Ok, so I wanted to run Memtest86, so I downloaded it, burned it to DVD and made it a bootable DVD. I read on their site this should work just fine. So I set my Boot Priority to DVD Drive first, as I usually do when using a Bootable disk. So it restarted . . . nothing happened. No idea, because usually it asked me to "Press any key to boot from disk" on a black screen, but that didn't come up this time. I checked in Bios, and it said CD-Rom was still first boot priority. I checked, and normal DVD's run, i.e, movies or games. So I inserted my Windows bootable disk to see what was up...and it doesn't work either. I tried pressing F12, which is a feature of my Bios to use a "Fast-boot" to select what to boot fast without editing the Bios. This did not work either. Please help, thank you.
