What's wrong with my small form factor Dell? Using known-good DVD drives my burns ALWAYS fail verification! Info: I've got a fresh install of 32 bit Windows 7 professional on a quad core Q9400 Dell Optiplex 780. The memory is a 4 gb stick of Kingston; the hard drive is a new 500 gb Seagate 7200 rpm. I'm using Verbatim media. I've tried a brand new burner and I've tried several burners which work perfectly in my laptop, but it's always the same - data verification failure. For software, I've tried Nero Lite and I've tried ImgBurn (Infrarecorder refuses to create the image for burning on my machine... ???). What should I try next?
