Thanks for your suggestion but I tried that but the problem is that this computer is refurnished and does not have the hard drive which dell originally installed. The only IDE & EIDE Controllers they have is for a Hitachi Deskstar 180GXP Family (20,30,40,60,80,120GB) Hard Drives. The hard drive in this computer is a Maxtor.
Hard Drive Model: Maxtor DiamondMax Plus 8
Capacity: 4 Gb
The hard drive is not making any unusual sounds. Its just making the usual sounds of it powering up and spinning. I also noticed that under Primary Drive in BIOS, when there is a disk in the disk drive it says UNKNOWN but when there's no CD in the disk drive it says Maxtor N40P.
