There can be more than one reason, why the computer can't play any sounds. These are discussed below:

If you have a desktop computer, it may or may not have a separate sound card. But in case of laptops, the sound card is integrated into the motherboard and cannot be removed, so some of the solutions may not apply to laptops. Also, new laptops come with built-in speakers, so the external speakers and cabling problems may not apply here, unless you use external speakers or headphones.

So, where do you start, when you can’t hear any sounds from your computer?

Before we start with the solutions, did you try the simplest solution first? Rebooting or restarting the computer is the simplest solution and should be tried first. If you didn’t already reboot, try it now. The sounds may just work after a reboot.

Can you hear the Windows startup sounds from the computer? If you can hear the Windows startup sounds, the sound card is working fine. If you can’t hear any startup sounds, enable the System Sounds in the Control Panel, if they are disabled. If you aren’t able to enable the system sounds and they are grayed out, you may need to install the sound driver.

Are you trying to play an audio CD, and not getting any sound? If you can hear the System Sounds, but can’t hear anything from the audio CD, even though your audio player software tells that it’s playing the disc, the problem is most likely with the digital cable that goes from the CD/DVD driver to the sound card (or to the motherboard).


One side of this cable goes into the back of the CD/DVD drive and the other goes into the sound card or on to the motherboard (in case of motherboards with built-in sound).

Are the speakers connected to the proper sound port / jack, at the back of the computer? Are they powered ON? External speakers generally have a separate power adapter, which plugs into the wall socket or any other power source. Is the speaker volume control, set to a comfortable level? If not, turn it to the middle position.

If in doubt, test your speakers by connecting them to another sound device like CD/DVD player or a radio/tape player, or any sound source. If you can hear sounds from the speakers, they are fine.

Check that the speaker pin is connected to the green jack on the back of the computer. Also, check that the sound (check speaker icon in the system tray) isn’t muted. Such a simple thing, which can happen accidentally, can confuse some people when they can’t hear sounds from their computers. This can get overlooked because the speaker icon may be lost between many other icons. Click it and un-mute the sound, if it’s muted.

Note: If you can’t see the speaker icon in the system tray, you may need to enable it from the Control Panel. From the Control Panel, double-click “Sound and Audio Devices” and check the box that says “Place volume icon in the taskbar” and click OK.

Try plugging in a pair of headphones in place of the speakers, to check whether you can hear anything. Play a song or music CD or any sound file, which you may have on the computer. If you don’t have one handy, you can run a command to test your sound:

Click the Start button, and then click Run (or Search, in Windows 7 / Vista). Type the following command and then press the Enter key: dxdiag

Click on the ‘Sound’ tab to see the details of your sound card. You can also test your sound card from this tab. Note the name of the sound card and the manufacturer, on a piece of paper.

If you can’t see the name of the sound driver, or aren’t able to hear the sound by using the ‘Test DirectSound’ button, or you get an error, the problem may be with the sound driver. If the sound worked sometime ago and now it isn’t working for some reason, the simplest solution for re-installing the sound driver is to do a System Restore. Restore the system to a date that you know, when your sound worked. Check out the following links for a short tutorial on System Restore

Note: Current documents, files and e-mail are not affected by System Restore. If you get an error like “Restoration Incomplete. Your computer cannot be restored“, undo the last action by selecting “Undo my last restoration”.

Here’s a youtube video on how to restore a system with System Restore: http://www.youtube.com/watch?v=mU5yqvye57E

Here are step-by-step tutorials on System Restore:

http://windows.microsoft.com/en-US/windows-vista/System-Restore-frequently-asked-questions

If System Restore didn’t help or you get a message that System Restore couldn’t be completed, try the following:

Start the Device Manager (Start -> Run -> devmgmt.msc and hit the Enter key). In Device Manager, Click the + sign next to “Sound, video and game controllers”. See that the sound driver that you noted from dxdiag above, is listed.

Doube-click this sound driver. Device Manager should give a status message that the driver is working fine. If the driver isn’t there or if it shows a yellow exclamation mark, shows under other devices, or gives any other kind of status message, reinstall the driver. In any case, it doesn’t harm to uninstall and reinstall the driver.

From this sound driver properties page, you may also click the Troubleshoot button, to open the Sound Troubleshooter in the Windows Help and Support Center.

SOURCE: dell 4700c

take off the side panel of the computer and listen to it a little closer when its on. there are very few actual moving parts so i should be fairly easy to isolate the noise. if it's a fan anywhere in the computer it can be replaced for less than 20 dollars and shouldn't be left till it dies, replace it , it's protecting something.

If it's a cd drive making the noise , it can be replaced for 25 dollars.

If it's the hard drive, then you need to back up your important files AS SOON AS POSSIBLE, because when it crashes, you generally have a hard time retrieving stored information from it.
hard drives can be replaced for 50 to 150 dollars depending on type and how large it is.
Most times the noise from a computer comes from the fans and power supply, then the cd/dvd roms , then the hard drive : so check them in that order. post here again if you need further assistance.. Regards

SOURCE: Swap Dell 4700C Motherboard into New Case

Let's make this really simple, though you are apparently knowledgeable enough to realize the answer,
without my intervention.

Knowing what we both know about the units and their present condition.
1. The 2400's board is dead.
2. The 4700C's network card and CD Drive (hence, the slots and/or inputs on the motherboard, and
therefore the motherboard are also dead.) I am willing to bet you that in another system, the network
card and CD actually work.
3. All Dell® system's are totally proprietary in the board design and even the placement and removal
procedures for all drives.
4. Neither system is state-of-the art, but you knew that also.

ergo

Since you know enough to protect for ESD I will take a shot and acknowledge that you could build from
a barebones kit a new unit, using any of the parts from the two systems that actually work and end up
with a brand new system that will work for you for an extended time period into the future.

SOURCE: I have dell dimension 4700c I just get black

You should try a different monitor if you can. I can't tell if you see the motherboard's BIOS, but if you don't, then I bet it's the monitor. If you can't find another monitor to plug it into, your TV might have the correct input. Hope this helps!

Dell Dimension 4700C Desktop PC, internet issue.


Try and test the computer and modem connection by hooking it up directly by an ethernet cable..

If the internet connection stays solid when cabled up..

Then try either changing or removing the wep or wpa encryption on your wireless network, and seeing if that allows the computer to stay connected.

Also try disabling the firewall on your computer, and also on your modem.

My Dell 4700C PC will not start


Sounds like a blown power supply. Easily fixed. Go the a local computer store and buy a 400+ watt power supply, open your case, remove the 4 screws in the back, all the power plugs and replace with the new one.
