No power to 12 volt, Hard drive, or Disk drives.

Most new power supplies can only be turned on via motherboard signal. That is why you have to plug in the 20/24 pin connector from PS to mo bo. When operating yellow wire is 12 volts and red is 5 volts DC. And black is ground.

SATA Hard Disk as a Slave b> An SATA hard drive is an internal hard drive that connects to your computer's motherboard. It is even possible to connect multiple drives to the same computer; however, only one drive can be the master hard drive; the other(s) must be slave drives. This is because the master drive has the operating system installed and must be used to boot up the system. When installing a new SATA hard drive onto your computer, you must set it as a slave.

Power down your computer and disconnect the cables. Remove the Phillips screws from the exterior of the computer case and slide the case open to expose the interior of your computer. Identify the hard drive at the front of your computer, then slide the new SATA drive in underneath. Insert the smaller power cable into the power port on the side of the SATA hard drive. Follow the power cable running out of the current hard drive and insert it next to it on the motherboard. Pull out the ribbon cable, which has three different connection ports: one on each end of the cable and one in the middle. The connection port on the middle inserts into the slave drive and is slightly different than the other two ends (the pins built into the port are in different locations than the other ends). Insert the middle connection port into the ribbon port on the back end of the SATA hard drive. Plug one of the opposite ends of the cable (doesn't matter which one) into the SATA connection port on the motherboard (your current hard drive is inserted here). Once connected, this completes your slave drive connection. Second SATA 2 Hard Drive as a Slave b> Installing a second hard drive in your desktop PC or notebook is an option used to increase hard disk space without losing or transferring the data from your original hard drive. Using this method not only increases hard disk space, it also increases the virtual memory space for the Windows operating system, increasing operational efficiency. One of the ways in which a BIOS can recognize the second hard drive is to boot it as a slave drive, with the primary hard drive booted as a master drive.

Turn the PC off and remove the desktop chassis. Refer to the pin connector diagram. This is displayed on the sticker, on top of the hard drive, for the position of the slave pin. Place the plastic connector on the slave pin as detailed on the diagram. Connect the hard drive to the power and IDE/SATA cable. Ensure the other ends are connected to the motherboard. Use the screws to mount the drive. Replace the desktop chassis. Turn on the PC. Enter the BIOS, by default this can be done by pressing F2. If this does not work consult your motherboard manual. In the BIOS, press right until the boot device tab is highlighted. Set the slave drive to boot following the primary drive. Read the bottom line and use the relevant key to save the settings. Restart the PC.
Hope it helps.

Trying the easiest solution first - It sounds as if the power is getting to the hard drive, but the information is not getting to the computer.

Is the IDE/SATA cable attached to the hard drive AND the motherboard?

Are the connections tight?

Is one end of the cable reversed - does pin 1 on the hard drive correspond to pin 1 on the motherboard?

Are the jumper settings on the hard drive set properly - Master/Slave/Cable select?

Are you replacing an IDE hard drive (uses a wide thin ribbon cable) with a SATA drive (uses a narrow, fatter cable). Can your motherboard handle a SATA drive? Perhaps you are trying to install the incorrect hard drive?

just plug in , these cards are plug and play sistem, after that you plug in you must to installa the driver software

OK your hard drive is an ATA drive.
You motherboard will have two hard disk controllers, on the 1st controller the ATA cable will have two connectors - a connector will have the C drive hard disk attached to it and the jumper on the hard drive will be set as the Master drive. You may also have a CD or DVD drive connected to this cable, if so then the CD or DVD drive will be jumpered as a Slave drive.
If the second connector does not have a drive connected, then you can connect the second hard drive to this connector BUT it needs to be jumpered as a Slave drive.
You may elect to connect the second hard drive to the second IDE controller instead on the first controller. If there aren't any drives on the second ATA cable then the second hard drive can be jumpered as either a Master or Slave drive.
If there is a drive on the second ATA cable you need to determine the jumper setting of that drive and then set the jumper on the second hard drive to a different setting. BOTH drives on the same cable CANNOT have the same drive setting.
After installing the second hard drive, check the BIOS configuration of the second hard drive, if the hard drive is detected then when Windows boots up you will see the hard drive and its contents.

Good day sir, let try to test first the power supply, Unplug the power cord, remove the 20 pin (24 pin for the late model) molex power connector from the motherboard, plug in the power cord, get a 2 to 4 inch jumper wire, short the green wire with any of the red or black wire on the molex 20 pin power plug, the result maybe the following:

1. you will see the power supply fan turn. you power supply is in good order. replug the power supply, and test again.
2. you will see the fan turn for a few second then stops. you power supply is selective, and may require a different type of motherboard. Get a new one.
3. you wont see the fan turn at all. get a new one.

If in case you are with #1. uinplug the power cord and remove all the expansion cards, data cables from the hard disk and cd drives. we are trying to isolate the problem. make sure that the only connected cables on the motherboard are as follows:

1. 20 pin power cable.
2. 4 pin 12 volt power cable (if applicable)
3. speaker
4. power switch
5. power led

Test the pc once more. plug in the PC. If still the board wont power on. problem with your motherboard. Note:make sure your RAM is good. Hope this helps.

Try removing all cards with the exception of the video. Remove all memory leaving (1) to boot from.
Disconnect power and reset the processor.
If you have a boot disk or copy of XP on disk, try to boot from the CD or DVD.
If the unit boots at all the problem may be the HD.
If not try downloading the BIOS update for your chipset.
Remove all extra drive, like secondary CD or DVD drives, Floppy or Zip drives.
You may have burnt the processor but I don’t think so.
Power supply is OK or you would not power up. Their are 3 or 4 supply voltages from supply, +- 12 volts, +- 5 volts and +-3.3 volts.
You may have a secondary 12 volt 4-pin plug but that is for on board video.
Try a boot disk and flash your BIOS, if you can.
Hope this helps.

Still have that Windows XP Pro full installation disk, that you used for this harddrive?

First:
Make sure all power cables from the power supply are connected.
You have a motherboard, (Intel D845GBV), that has a Socket 478 processor socket, and uses Intel Pentium 4 processors.

Computer Unplugged from power! Touch the metal frame of the computer case to relieve your body of static. Work on a table. IF you get up for any reason, then return, Make Sure you touch the metal frame, BEFORE you reach inside.

1.Make SURE the 4-pin ATX power cable from the power supply, is plugged into the 12 volt ATX connector on the motherboard.

[12 volt ATX connector on motherboard:
Bottom LEFT corner of the processor socket. You are looking at the motherboard with the processor at the top, and the ram slots to the right]

2.Make sure the 40-pin flat ribbon interface cable, is plugged into the harddrive correctly.

There is a faint red stripe along one edge of this flat ribbon cable. The red stripe designates Number 1 pin. (There are 40 pins on the back of the harddrive. [39 actually. One pin is blocked out]

As you view the back of the harddrive, the 4-pin Molex power cable, plugs into the right side. (All the way to the right)
The 40-pin flat ribbon cable plugs in to the left of the power cable.

Number 1 pin of the flat ribbon cable, is next to the power cable connection.

The red stripe, will now be close to the power cable connection on the harddrive, when the flat ribbon cable is plugged in correctly.

3.Make sure the 4-pin Molex power cable is plugged in firmly into the harddrive.

4.Check all power cables to the optical drive/s, and the main power cable to the motherboard.
[20-pin ATX power cable. To the right of the ram slots]
Now, close the computer case, plug the computer back into power, WAIT 1 minute, turn the computer on.

As SOON as the POST screen goes by, start tapping on the F2 key. You are going into BIOS Setup.

You should now be on the main menu in BIOS Setup. You can no longer use your mouse, you have to use your keyboard to get around in BIOS Setup.

At the top you will see headings in the header bar. Maintenance, Main, Advanced, Security, Power, Boot, and Exit.
Use the Right Arrow key and highlight Boot.
Press the Enter key.

Use the Down Arrow key and highlight Boot Device Priority in the drop down submenu. Press the Enter key.

Use the Down Arrow key and highlight ATAPI CD-ROM. Press the Enter key.

Now press the F10 key.
If Yes/No comes up, use the appropriate Side Arrow key, (Left or Right), and highlight YES. Press the Enter key.

IF Y/N comes up, press the y key for YES.
(It isn't a capital Y. The capital Y is shown for clarity. Do Not press the Shift key, and the y key. Just press the y key)
Now press the Enter key.

(F10 is to Save Changes. Y is Yes you want to save changes. The Enter key executes the command)

Your computer will now restart. You need to have that full installation disk in your optical drive. (CD/DVD drive)
Your computer will now boot from the full installation disk in your optical drive.

If your computer goes past booting from the installation disk, because you did not get it in there in time, don't worry.

Just press the CTRL key, ALT key, and DELete key, AT THE SAME TIME. (Not shouting)
This will restart your computer, and it will boot from the Windows full installation disk.

1. First of all, you must open the computer case (with power off), and werify the power cable and data cable of hdd. please detach and put them right back.
2. then power on your pc
3. you MUST press F2 for setup utility in order for correct setings of your bios. the message "strike F1 to retry boot, F2 for setup utility" came from the computer bios, not from Windows XP CD.
4. verify if you followed the correct procedure of installing an new hdd as is described on page 66 of owner's manual from dell.
