  1. Hi MrDrift,

    This link has some good steps to follow to solve this problem (incidentially it could be BIOS related and might be a bad CMOS Battery. If the battery is weak it could still keep the data and time properly but other settings could be lost). If you have a multimeter you could check the battery to see if it is run down, or it is cheap to just replace it anyway).

    Check out this link:
  2. Battery is now $5, but hey, you can't anything for $4.99 these days. It's #2032 from Radio Shack or any computer store.

    NTLDR can also be restored from a floppy or flash drive if you don't have the CD. I keep one handy.
