Question about Dell PC Desktops

2 Answers

Sound is scratchy

I have a Dell Optiplex 745. The sound is extremely bad. I cannot listen to any music or watch any U tube videos or watch a DVD. I tried calling Dell - they recommended a change in motherboard, which was done by them as the product was still under warranty. The sound comes out like a very bad 'am radio' with disturbances and screeching etc.
I was hoping not to have to reinstall the entire windows xp and all my programs. Is there a way to just check the sound files or replace a corrupted sound file in windows xp.
I have done the usual steps of replacing the external speakers and following the windows trouble shooting of the sound system without any luck.
I would really appreciate any help.

    The soundcard is integrated with the Motherboard. So I cannot install a new sound card.

    Thanks for your help

    Initially when I had called Dell, they had informed me that there was no way a new sound card could be installed as it was integrated with the motherboard. So they agreed to change the motherboard to resolve the problem. It did not make any difference.

    The computer is a small size. so there is no room for installing a new sound card. There are no empty slots for a sound card.

    Are there external sound cards avaiable?

  • skindoc Dec 26, 2008

    I am going to Circuit City right now to purchase an external sound card. I do hope this solves the problem. I shall post a comment by this evening if this works. My only fear is that the motherboard has already been changed once, and the new integrated sound card did not make any difference.

    I had one question before I purchase a new sound card which is about $75.00. A Dell technician told me it is highly unlikely that a sound card is causing my problem, because when I connect the speakers to the earphone jack in the front of the computer, the problem with the crackling and distortion still persists. He said the earphone jack bypasses the sound card in the computer.

    I don't know if that is an accurate statement. Perhaps someone could advise me on that.

    Make sure the speakers are plugged into the correct jack. Check that you do not have an analog ->digital mismatch.

I would suggest you get yourself a new sound card for the computer.
here are some from newegg http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=creative+sound+card&x=0&y=0


the 30usd card will do great, but if you want even better quality you could get the creative extreme audio they are all on that newegg shop page above.

    A computer can have more than 2 sound cards installed, this will fix your problem you wont need to remove the build in card, you can have both installed or disable the internal card from computer bios.

  • Ekse Dec 26, 2008

    it doesn't matter if you have a internal sound card, it can be disabled from computer setup / bios during start up. Or you can have both installed and working, you will just need to change one small setting in windows simply to use the new card instead of the internal old card.

  • Ekse Dec 26, 2008

    Yes there are external sounds cards, there are sound cards for USB for example Sound Blaster Go! http://www.soundblaster.com/products/pro...

    If I had to use a USB sound card I would go for the Creative its a great brand.

    drop me a comment if you need help in getting the windows to use the external sound card instead of the internal one. I can take over the computer for a moment and help you with it, but it debends if I'm available when you get back. Im on Finland time, its almost 8pm here.

  • Ekse Dec 27, 2008

    go to a real computer shop store and make sure you are allowed the return the usb card incase it doesn't work.




    The jack is connected to the sound card, try connecting on the back of the pc. I don't understand what he ment.

Yellow light power button


A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Remove broken headphone jack on an Optiplex 745


Since the Headphone jack is soldered onto the motherboard in most cases you could remove it by unsodering it from the MB. However, replacing it might cause another issue. You can always install a sound card that would allow you to have additional headphone jacks.

Dell 745 - only gets sound from speakers


Onboard sound does not need drivers. The little speaker is attached to the motherboard directly or by wires plugged into the motherboard. You need to check to see which speaker you have. Once you have found out, be sure that, if it has wires attached to it, that they are plugged in.

Bought a used Dell Optiplex 745 Desktop Computer. Seems to boot up okay, but no video. Want to check inside to see if any connectors are loose. How do you remove off the cover(s)?; I don't see any screws...


Hello,

To remove the side of the Dell Optiplex 745 cases you need to push the release latch on the back either top or side depending on whether it is a tower or a desktop. The latch just slides back and the side will release and the cover will pop loose. The normal issue with this model is not a bad video card, it is bad capacitors on the motherboard. We repair these boards all the time for a federal prison that is located near our office. Look over this guide we have posted on our site that explains what to look for and what to do about it. http://www.ccl-la.com/blog/index.php/dell-optiplex-745-repair/ The repair is easy to do if you can solder, We have 4 units in right now for repair. Check out your board, I would bet his is what your problem is.

I hope this helps, if so please rate our solution.
