OK I've seen a few references to this problem but the posts are several years old on earlier models. On startup I get power indicator, black screen, DVD drive drawer pops out then 7 beeps -- 1 loud and 6 lower, repeating. If I hold down the power key for a few seconds the screen turns very bright white and after about 15 seconds I get the Windows 7 login screen. It seems to work well after that but same sequence after subsequent startups. Tried the blanket fix and updating BIOS as well as some Dell-run optimization with no success. Thanks for any input.
