    ???? Strange. If you go into the BIOS, does the computer see the hard drive in there?

There is no master resest button , if your hardrive is not working it is most likely dead or has a loose wire.

hardrives arent designed to last for ever,what you can try to do is unplug the mains plug leave the pc for an hour or so , and then before pluuging it bavck in press the power switch this should clear all power from the motherboard and power supply.

you can also try reseting the cmos by removing the small battery on the motherboard.
it is most likely you H/d is dead,following benwabnicks advice have you been able to see the H/d in bios. to enter bios press f10 or another key immediatley after powering up the pc, it usually tells you on screen press enter or f10 or another key to enter bios or setup.

let us know how you get on

    yes it should pick up the hardrive in bios.

    it will say something like 

    toshiba ide 492390 mb
    samsung sata 978930mb 

    partitions and stuff

    In printed circuit board you see "CS" "master" "Slave"
    I recommend place the jumper in "master"

    What happened is that your hard drive has died. The hard drive is the only moving piece of machinery inside a computer besides obviously the fans that can make that type of noise. The best course of action would be to buy a new hard drive, install it, then install Win7 again. Here is a good replacement drive.

    Dell 340 will not recognize my cd or dvd drive.

    check if you see any light on the drive, if yes. then the power is there and then the problem is with the data cable of the cd drive. try to repalce the cd drive with another cd drive. if it still doesnot work and if the same cables work with the hard drive, then the cd drive has gone bad. and if the new drive also doesnot work then reinstalling the operating system should fix the problem only and only if it appears in the bios. if it doesnot appear in the bios. then the problem is not of the operating system. then its the motherboard.

    Dell Precision 340 will not boot past the bios

    It is possible that one of the drives are causing the proble. Disconnect all drives Hard drives, CD, DVD, BLUERAY,Floppy etx and turn the system on if it boots then shut it down and connect the drives one at a time until you find the one at fault.. If this fails then the problem resides in the main board itself, YOu said you cleard the cmos, try reseating the processor (removing and then putting it back) then flashing the bios (clear the cmos) ,, if that fails then you may need to replace the mainboard.

    Hard Drive Problem

    Sounds like your hard drive is crashed. You will most likely need to replace it. Before it gets totally crashed try to backup your important data while it is running.

    Hope this helps you
