My desk top computers screen went black, can my data be save on the hard drive and how can i take it off


Not posting the model number of the Dell desktop computer, get's you generic information.

The model number can be found on the back of the computer, next to the Windows product key.

Moving on......


Suggest use an external enclosure.
Remove the harddrive from the computer, and install it in an external enclosure.

The external enclosure has a USB cable, and you just plug it into any available USB port, on a working computer.

Then go to My Computer, or Computer; depending on which Windows operating system the computer has; and double-click on the drive letter that corresponds with the external enclosure.

(WinXP: Start > My Computer
Win Visa / Win 7: Windows logo button > Computer )

Examples of drive letters;

C: Drive = Harddrive of the computer you are using

D: Drive = Separate partition on the harddrive for Restore files, or is for the optical drive (CD/DVD drive)

E: Drive = Optical drive generally, but may be the drive letter that corresponds to a Removable Device.
The external enclosure you plugged in, is a removable device.

None of the above is 'etched in stone', except the C:Drive
Things change from computer to computer, and the way you may have it set up.

Easy way to know?
Before plugging in external enclosure, open My Computer, or Computer.
Look at what each drive letter corresponds to.

Now when you plug the external enclosure in, you will see the change; and know which drive letter corresponds to the external enclosure you just plugged in.

Double-click on the name next to the drive letter, that corresponds to the external enclosure you plugged in.

Go into My Documents, or Documents.
Again, depends on which version of Windows you have.
Win XP = Start > My Documents
Win Vista / Win 7 = Windows logo button > Documents

Now open each folder, until you get the personal files you want to keep.
Photos, music, videos, documents you have created, or downloaded.

You cannot remove programs, or applications. Just your personal stuff.
(You can, but that is for a separate discussion)

Also open Downloads.
(WinXP = Click on Start > My Documents > DOUBLE-click on Downloads.

Win Vista / Win 7 = Click on the Windows logo button (Start), click on Documents, click on Downloads.

Harddrives are measured in Width.
2-1/2 inches across for a laptop harddrive. 2.5 inches.
3.5 inches for a desktop harddrive.

Don't know what Dell this is again, don't have the model number.

Cannot tell you if the harddrive is an IDE (PATA) unit, or a SATA unit.

So you will need either a 3.5 IDE (PATA) external enclosure,
OR,
a 3.5 SATA external enclosure.

There are external enclosures that are 3.5 and IDE/SATA, also.

Basic examples,

Easy way to identify what type technology is used, for the harddrive in your computer; IDE/PATA, or SATA;

Power cable for an IDE/PATA harddrive,

SONY VAIO PCV R53 39 DS WON'T BOOT UP


Pull the harddrive out, install in an economical external enclosure.
The external enclosure has a USB cable.

Plug the USB cable into any available USB port, on a working computer.

Go to My Computer, or Computer; and double-click on the drive letter, that corresponds with the external enclosure.

(Actually with the harddrive in that external enclosure, it is now an external harddrive)

http://esupport.sony.com/US/p/model-home.pl?mdl=PCVR539DS&LOC=3#/howtoTab

It's an IDE harddrive. Also known as a PATA harddrive.

A harddrive is measured across it's width.
2-1/2 inches across is a laptop harddrive.
3.5 inches across is a desktop harddrive. (3-1/2 inches)

So you need a 3.5 IDE (PATA) external enclosure.
One example,

After installing windows 7 the sound drives were not working , no sound


Hi,

Check Device Manager to for any "unknown devices", your audio device driver might be one of those. Unknown devices usually appears if the device driver (ex. audio driver) is not installed. You can also find an "exclamation point" under "Sound, video and game controllers" if there is conflict on the driver causing no audio to be heard from the unit.

To resolve the issue, you can either use the Drivers installation disc which came with the motherboard or Right-click on the "unknown device" and select "Update driver" button.

For pc users who doesn't know how to check device manager, follow below steps:

Windows XP
- Start > Run > type devmgmt.msc on the box then hit enter key. or you can also
- Start > Right-click My Computer > Properties > Hardware tab > Device Manager

Windows Vista and 7
- Start > type devmgmt.msc on the search box then hit enter key or
- Start > Right-click Computer > System Properties > Device Manager (link at the left pane)

Hope this helps.

Operating system not found on any devices


well, it probably doesn't recognise that you have an operating system (if you do) because of possibly a corrupted installation...try reinstalling windows on your harddrive, but it's recommended to format anything on your harddrive before you reinstall windows....if you need to backup what you have on your harddrive, you could buy a casing for it so that you can make it external.
