At some point we were having issues with blue screens due to what seemed like nvidia drivers crashing constantly, and one of the options on one forum was to unplug or replace the CMOS battery. Unplugged it and put it back in, and not a single blue screen for about 6 months.  The blue screens started again with the Nvidia crashes (I can NOT find a stable driver). So the battery was unplugged again, but this time when we start the comp it says "reboot and select proper boot device, or insert boot media in selected boot device and press a key."


"Boot mode is set to: Legacy; Secure boot; off

Legacy boot:



Other Options:

BIOS Setup

Enter ePSA

Change Boot Mode Setting"


Under Aptio Setup Utility>Boot

"Set Boot Priority is set to [Legacy]


Set Boot Priority

1st Boot [USB Floppy]

2nd Boot [USB Hard Disk]

3rd Boot [USB CD/DVD]

4th Boot [Hard Disk]

5th Boot [CD/DVD: HL-DT-STDVD+/-RW GA31N

6th Boot [Network]"


It is an Alienware x51, I can't give much more info as we really don't know where to look for it. ANY help getting this computer to boot into Windows/my HD would be appreciated.

It may be time to replace, not merely remove, said CMOS battery.  It's cheap and easy to do...may resolve your issues or help pinpoint such.
