SOURCE: no sound on my dell optiplex 330

Unless you have headphones, you need speakers, preferrably amplified speakers.
Another way the address the issue is to use a cable to connect your computer to your home stereo if it has an auxilery input (aux/cd/tape input) then all you need is a cable with two male RCA plugs on one end and an 1/8 inch stereo plug on the other end.
The 1/8th inch plug goes into your computers' sound "out" and the rca's go into the aux/cd/dvd "IN" on the stereo.
this cable can be purchased for under 10 dollars at walmart, though amplied speakers wont be much more expensive.
Hope this helps you decide which direction to go..
Regards..

SOURCE: my dell optiplex 790 desktop pc have a error code is 2-3-4 and some times 1-2 please i want help

Hello there
I have found two things which will help you.
A Technical Guide to the Optiplex 790 which will download from here:
http://www.dell.com/downloads/global/products/optix/en/optiplex-790-tech-guide.pdf
It is in pdf format and can be saved to your computer for future reference.
Also I found a Service Manual here:
Dell OptiPlex 990 Desktop Service Manual Page 76
If you click on the green download button at the top of the page then you will taken to a page where you enter 3 letters that are given to you and you can then opt to download it or view in your browser. In both cases it can be saved to your computer.
The latter has a good section on beep codes, and light codes on page 73 ( Chap 20) and following.
It gives your 2-3-4 as a possible USB failure, so try booting with no USB items attached - printer, flash drive, scanner, external drive etc.
It gives your 1-2 code as an expansion card failure and gives various means of checking.
Hope this is helpful, if so would you please register that with Fixya
Cheers

How to fix power supply in Dell optiplex 790


If a power supply has gone out in a PC the only cost effective thing to do is replace the power supply. If the Optiplex is the Dell I'm thinking of it requires a slim power supply. You may have to contact Dell to purchase another power supply.
