Usually the white connectors are from the power supply for additional plug-ins. If the Hard Drive has two cables hooked into it and you can trace one to the power supply and one to the motherboard then it is connected. If everything is connected, try a different connector from the Power Supply. If that doesn't work it could be the connecting cable from the HD to the mother board, or it could be the HD has failed.

SOURCE: Hp compaq presario v3000 is not loding the OS, show an error

  • as you boot the computer, start tapping the F8 keys
  • From the boot menu, select Safe Mode
If this seems to work, you can try restoring the computer to an earlier point from Start > All Programs > Accessories > System Tools > System Restore.
If Safe Mode also fails to load, you would have to check your disk for errors or you may have to install XP all over again.
Please get back, if you need any further help.

Problem with COMPAQ DC5850 SFF ATH/5000 2GB80GB COMBO WVXP PC Desktop hp compaq dc5850 pc won't turn on after plugging in old hard drive for transfer Posted by Author imageGuest on 1/4/2013


The h3ll you say.

(Kidding around)

Let me see if I understand this straight;

You unplugged THE harddrive to your computer..............

Then you plugged an old harddrive in, and expected to be able to use it.

Expected to because you've done it in the past.

Really

Curious;
1) Was it an old harddrive you had in the computer, removed it; and had a larger one installed?

2) Is it one that you have had in another computer?

Here's what I know, and why I'm asking;

When Windows is installed on a computer it assigns hash values, to certain major hardware components.
For example;

A) Processor
B) Motherboard: To include the motherboard chipset, and BIOS program. (To include version and date)
C) Harddrive
D) Graphics chipset

Change any two of these hardware components, and Windows will think it is being stolen. Put on another computer.

Microsoft User's License states, "One GENUINE copy of Windows per ONE computer"

(Microsoft makes one Master disk, and from it all GENUINE copies are made, and sold to the consumer)

Now if you stated you installed the old harddrive as a Slave drive; then I could understand.

P2 connector?
That is a Power Supply power cable.

According to specifications the Harddrive is a SATA unit.

http://h10010.www1.hp.com/wwpc/ca/en/sm/WF06b/12454-12454-64287-3328896-3328896-3658105-3687950.html?dnr=1

Internal Drives - Hard disk controller -SATA 3.0Gb/s NCQ SMART IV

The power cable to it is a SATA power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Probably what your P2, and P3 power cables are.


http://www.ebay.com/itm/HP-DC5850-SFF-Motherboard-SPS-461537-001-/310417711958?pt=Motherboards&hash=item4846566356

P1 will be a 24-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

P4 cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

P5 cable, MAYBE, (Might be P3 too)

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

And P6 power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#floppy

This type of power cable is also used on a Card Reader.

To conclude;

A) SATA harddrive has to have a SATA power cable, and SATA data cable.

The SATA power cable's connector is wider, than the SATA data cable's connector.
15-pins for the SATA power cable connector; 7-pins for the SATA data cable's connector,

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

The above is a general example of a SATA data cable, and it's respective connector on the motherboard.

Your SATA data cable connectors on the motherboard, are of a different style than the above.

You have Four SATA connectors on the motherboard;
1) Light Blue
2) Orange
3) Dark Blue
4) White

First, please disconnect all USB devices and then perform the following steps:


Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.



In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".



Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".



Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.


for xp


click start control panel administrative tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X


you will need to update/reinstall drivers

right click to reinstall drivers


if you can see your usb but its not working

ports(com&lpt)right click update driver


sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable


just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again,



if you can see your usb drive but its not working

ports (com&lpt) right click update driver if this fails to fix the problem


check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts


hope this helps

IBM thinkcenter says no os after installing DVD writer


Did you install a SATA or an PATA (IDE) drive?

First check that the data cables are connected to both the hard drive and the motherboard. (I know that I've frequently had the cables come loose from the motherboard on my ThinkCentre 8433 when I work in the case.) Also check that the power cables are firmly connected.

Next make sure that you have no disc in the DVD writer. (Or enter the BIOS by pressing F1 (IIRC) repeatedly on start up. Make sure that the hard drive is the boot disc.) While in the BIOS, you can check if the hard drive is recognized by the motherboard. If you don't see the disc listed, recheck the data and power cables.

If the hard drive was working before you replaced the dvd drive, you may have changed the master/slave assignment on the drives (if they are both IDE). Remove the drives from the computer and check the jumpers. (These will depend on the manufacturer. Use either cable select or master/slave as needed) The boot drive should have the jumper set to master or cable select. In the case of cable select, the boot hard drive should be connected to the black connector. The slave drive goes to the grey connector.

If you connected a SATA drive, try swapping the SATA ports (SATA 0 or SATA1) that has the optical drive connected to it.

The next thing to try requires either the Windows install or upgrade disc for your version of the OS (including the Service Pack) or a third party partition manager/repair utility disc. You'll need to reset the boot order to boot from the optical drive (or press F12 on starting the computer). Use the Recovery Console (for the Windows disc) to find any existing OS installs on your hard drive and attempt to repair the master boot record or boot sector if it still exists on the drive. Please add a comment with your OS for specifics on using the Recovery Console. (I replaced my WinXP with Win7 and the methods are different.)

You may have been unlucky and had the hard drive fail while you were working in the computer. See if the recovery partition (F10 on boot) still works or use your system image (Rescue and Recovery DVDs) will restore your computer to the last backup. Try doing the restore to a new hard drive if the recovery discs don't work.

I hope this helps. Please add a comment with any comments that will help me give more specific assistance for your missing OS.

Unpluged small ribbon cable from mother board installing hard drive need to know where it plugs in


If it's an IDE cable it goes into the IDE 0 or IDE 1 on the motherboard.
It's your primary drive so it should go into the lowest number.

If it's an sata drive the and it's your primary drive it goes into the lowest numbered sata port on the motherboard.

How to fix a NTLDR is missing error


Fixes for NTLDR Errors
  1. Restart the PC. The NTLDR error could be a fluke.

  2. Check your floppy and optical (CD/DVD/BD) drives for media and disconnect any external drives. Often times, the "NTLDR is Missing" error will appear if your PC is trying to boot to a non-bootable floppy disk, CD/DVD/BD, or external hard drive or flash drive.

    Note: If you find that this is the cause of your problem and it's happening a lot, you might want to consider changing the boot order in BIOS so the hard drive with Windows installed is listed first.

  3. Check the hard drive and other drive settings in BIOS and ensure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including NTLDR errors.

    Note: There is usually an Auto setting for hard drive and optical drive configurations in BIOS which is usually a safe bet if you're not sure what to do.

  4. Restore the NTLDR and ntdetect.com files from the Windows XP CD. Restoring these two important system files from the original Windows XP CD may do the trick.

  5. Repair or replace the boot.ini file. This will prevent the NTLDR error if the cause of the problem is a boot.ini file that is not configured properly for your Windows XP installation.

  6. Write a new partition boot sector to the Windows XP system partition. If the partition boot sector has become corrupt or isn't properly configured, you may receive the "NTLDR is Missing" error.

  7. Repair the Windows XP master boot record. NTLDR error messages may also appear if the master boot record is corrupt.

  8. Reseat all internal data and power cables. NTLDR error messages could be caused by loose or malfunctioning IDE cables.

    Try replacing the IDE cable cable if you suspect it might be faulty.

  9. Update your motherboard's BIOS. Occasionally, an outdated BIOS version can cause the "NTLDR is Missing" error.

  10. Perform a repair installation of Windows XP. This type of installation should replace any missing or corrupt files. Continue troubleshooting if this does not resolve the issue.

  11. Perform a clean installation of Windows XP. This type of installation will completely remove Windows XP from your PC and install it again from scratch. While this will almost certainly resolve any NTLDR errors, it is a time consuming process due to the fact that all of your data must be backed up and then later restored.

    If you can't gain access to your files to back them up, understand that you will lose them all if you continue with a clean installation of Windows XP.

  12. Replace the hard drive and then perform a new installation of Windows XP. If all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive.

How do i format a hard disk that wont work


If it's truly broken you can't format it. Make sure the drive is being "seen" in the BIOS of your computer (use SETUP when the computer starts; watch screen for key to load SETUP). If you don't see the drive, it might be bad. Also check that the power cable to the drive is firmly connected. Hard drives can go bad - hopefully you have a backup "in case!"

Hi tracey,

Cause for the NTLDR missing:
  1. Computer is booting from a non-bootable source.
  2. Computer hard disk drive is not properly setup in BIOS.
  3. Corrupt NTLDR and/or NTDETECT.COM file.
  4. Misconfiguration with the boot.ini file.
  5. Attempting to upgrade from a Windows 95, 98, or ME computer that is using FAT32.
  6. New hard disk drive being added.
  7. Corrupt boot sector / master boot record.
  8. Seriously corrupted version of Windows 2000 or Windows XP.
  9. Loose or Faulty IDE/EIDE hard disk drive cable. are
Solutions:

Computer is booting from a non-bootable source


Windows XP users
  1. Insert the Windows XP bootable CD into the computer.
  2. When prompted to press any key to boot from the CD, press any key.
  3. Once in the Windows XP setup menu press the "R" key to repair Windows.
  4. Log into your Windows installation by pressing the "1" key and pressing enter.
  5. You will then be prompted for your administrator password, enter that password.
  6. Copy the below two files to the root directory of the primary hard disk. In the below example we are copying these files from the CD-ROM drive letter, which in this case is "e." This letter may be different on your computer.

    copy e:\i386\ntldr c:\
    copy e:\i386\ntdetect.com c:\

  7. Once both of these files have been successfully copied, remove the CD from the computer and reboot.
Misconfiguration with the boot.ini file

Edit the boot.ini on the root directory of the hard disk drive and verify that it is pointing to the correct location of your Windows operating system and that the partitions are properly defined. Additional information about the boot.ini can be found on document CH000492.
Attempting to upgrade from a Windows 95, 98, or ME computer that is using FAT32
If you are getting this error message while you are attempting to upgrade to Windows 2000 or Windows XP from Windows 95, Windows 98, or Windows ME running FAT32 please try the below recommendations.
  1. Boot the computer with a Windows 95, Windows 98 or Windows ME bootable diskette.
  2. At the A:\> prompt type:

    sys c: <press enter>

  3. After pressing enter you should receive the "System Transferred" message. Once this has been completed remove the floppy diskette and reboot the computer.
New hard disk drive being added

If you are attempting to add a new hard disk drive to the computer make sure that drive is a blank drive. Adding a new hard disk drive to a computer that already has Windows installed on it may cause the NTLDR error to occur.
If you are unsure if the new drive is blank or not try booting from a bootable diskette and format the new hard disk drive.
Corrupt boot sector / master boot record
It's possible your computer's hard disk drive may have a corrupt boot sector and/or master boot record. These can be repaired through the Microsoft Windows Recovery console by running the fixboot and fixmbr commands.
Additional information and help in getting into the Microsoft Windows Recovery console can be found on document CH000627.

Seriously corrupted version of Windows 2000 or Windows XP

If you have tried each of the above recommendations that apply to your situation and you continue to experience this issue it is possible you may have a seriously corrupted version of Microsoft Windows. Therefore we would recommend you reinstall Microsoft Windows 2000 and Windows XP.
If you are encountering this issue during your setup you may wish to completely erase your computer hard disk drive and all of its existing data and then install Microsoft Windows 2000 / Windows XP. Additional information about erasing the computer and starting over can be found on document CH000186.

Loose or Faulty IDE/EIDE hard disk drive cable
This issue has been known to be caused by a loose or fault IDE/EIDE cable. If the above recommendation does not resolve your issue and your computer hard disk drive is using an IDE or EIDE interface. Verify the computer hard disk drive cable is firmly connected by disconnected and reconnecting the cable.
If the issue continues it is also a possibility that the computer has a faulty cable, try replacing the hard disk drive cable with another cable and/or a new cable.
