Ok, I'm one those guys that leaves their comp on for weeks at a time. The comp works totally fine when I have it on. So every 1 - 2 weeks or so, I shut down the comp and leave it off over night. When I try to boot up the next day, one of my harddrives (doesn't contain windows) starts making a clicking noise when it is trying to be detected by the mobo. Sometimes the drive gets detected sometimes it doesn't, however with the clicking, the boot up process is slow. So I have to turn on and off the comp a couple of times until the hard drive doesn't have the clicking sound and the comp boots up and works totally fine. Can anyone tell me what might be wrong? I was thinking the hard drive might be dying but I just bought it last year, and it only clicks on boot up, never when the comp is finished booting and running. Thanks!
