Hard Drive Problems on Start Up

[TheAceOfSpades]

My Hackintosh works perfectly fine aside from two problems, the internet (I have a gigabyte mobo. addressing this problem elsewhere), and the boot up with hard drives. My hackintosh lags at boot to the point of not starting up sometimes when i boot with hard drives plugged in. To clarify actually it will boot perfectly fine with my external USB hard drives or nothing at all. If I boot with a flash drive in or my second internal hard drive (which is a time machine drive) it doesn't work. Ive selected the drive i want osx to boot from. Ive installed with DSDT; Ive changed the settings to boot Order: Hard drive, Cd Rom, Disabled; Ive reformatted and fixed permission for troubled disks and Ive installed universal 3.0 USB from multibeast. Need some help please
