Windows 8.1 Boots DOG SLOW With samsung 840 EVO with/without rapid mode enabled

it takes 100 seconds for my machine to boot. when my brothers machine boots in 10 seconds. His cpu is only 100mhz higher than mine and i have a faster gpu. Was it the way the files were copied from the WD Caviar black i had? i used samsung magician, or is it the hardware. is there something wrong with the drive? if there is something wrong, is there a way to fix it?

There are many variable to check.
Is your motherboards set to run in AHCI mode?
Are you plugging in your SSD into a SATA 3 port?
Have you check the settings in your motherboard's BIOS to reduce hardware checks and turned off CSM.
Is trim enabled for the SSD?
