The BIOS in my laptop shows twice before the computer finally boots.

I purchased a Sager NP9370 last year and the computer ran fantastically until a few weeks ago. Windows slowed down drastically in a few seconds, then froze solid. When I restarted the computer the entire hardrive was corrupted (It took about 2 hours for the chkdsk utility to get it to a running point again, but no programs worked and windows was very sluggish) so I reformatted and re-installed windows. After this reformat my bios will show up, followed by a black screen with a flashing white bar in the top left, before returning to the BIOS. After that point it will boot like normal. This really isn't a HUGE problem, but it's incredibly annoying as it drastically increases the time it takes for my laptop to boot.

It may be going through a "double boot" on account of a dodgy hard drive that's starting to fail, causing a drive detection hiccup.
You'll need to test the drive with the drive maker's diagnostic software for DOS which loads from a bootable CD.
