sometimes my hdds don't start
Today I just go back to my room after leaving for 2 weeks and went to turn on my computer and it just hung part way through post and I didn't hear and hdds come on. After opening the case and using compressed air and checking connections I tried booting up again and it worked. However this does seem like a problem to me since most of the time when I power on the computer it sits at the spot where it hung today for noticeably longer then I hear a hdd click on (not the click of death) but just turning on. Could there be a problem here? Is there any other way to check for sure? I ran hd tune and no errors showed up on the drive and the S.M.A.R.T status reads ok on both drives.
