20 Most Recent Dell OptiPlex GX620 PC Desktop - Page 7 Questions & Answers

do you mean you replaced the power supply of the monitor?. ok, does it the same specification the voltage and amper rating, from the original power supply?. if yes does the power indicator, stay or blinking?.just let me know if this is what you are asking for, so i can give some further solution.

It uses non-ECC DDR2 533Mhz memory (aka PC4200). Any of these will perform quite happily with that motherboard: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007611+600006096&QksAutoSuggestion=&ShowDeactivatedMark=False&Configurator=&IsNodeId=1&Subcategory=147&description=&hisInDesc=&Ntk=&CFG=&SpeTabStoreType=&AdvancedSearch=1&srchInDesc=

You need to go to the Dell Support site and download the drivers for the sound car, it is not part of the operating system.

Hi,
if you're not getting any sound from your optiplex it means either your sound card is bad or the driver is missing or corrupted. You should change the sound card if the first is the case or update the driver if the later is the case. I strongly believe that it's the driver, do that first and if it doesn't work, change the sound card.
Hope this helps
pls vote this

Please download the sound driver here and re install on your pc : www.nodevice.com/driver/company/Dell/SOUND.html www.notebook.driversdown.com/notebook-drivers/r_1_1.shtml

I'm sorry but this is not a warez site...We can't give out activation keys or access codes, and we cannot help you try and bypass copy protection.

Hi, you should check first your motherboard specially your memory module. Clean it and try to insert it again correctly.

enter bios by pressing either f12 or f2 or whatever key it says to press to enter setup. once the bios screen loads find boot device priority. change it accordingly, press whatever key you need to press to save changes and reboot If you need further help, reach me via phone at https://www.6ya.com/expert/joel_63c670a84e9f6a97

Hi, there. A slow Dell computer can be caused by many many reasons such as outdated hardware, overload start up programs, corrupt registry issues, too many junks, virus attack, poor security software taking too much system resources, remnants of uninstalled applications etc. The fact is, you should keep some system maintenance job regularly. If you don't want to do the job manually, try the Dell speed up solution available here: http://www.speedupslowdell.com/

Please try by resitting the ram.If the problem persists try by removing the cmos battery for some time. if problem is not solved then try with another smps.if all fails then your motherboard is gone bad.

With any computer on, plug a network cable from the computer to the jack if you get two likes on the computer the port is good, or at least functional.

Two wire are needed to attach a new hard drive.Please refer to the links below ,to see how the attaching cables looks.This cable is connects Hard drive to MotherboardSATA Data CableThis cable connects Hard drive to Power SupplierSATA Power Cable

One of your memory chips is bad.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting. Diagnostic Lights CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide. To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4"on the front or back panel. The lights can be off or green. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. If the POST portion of system boot completes successfully, all four lights display solid green. If the computer malfunctions during the POST process, the pattern displayed on the LEDs may help identify where in the process the computer halted. NOTE: The orientation of the diagnostic lights may vary depending on the system type. The diagnostic lights can appear either vertical or horizontal.

Problem Description

Suggested Resolution The computer is in a normal "off" condition, or a possible pre-BIOS failure has occurred. The diagnostic lights are not lit after the computer successfully boots to the operating system. Plug the computer into a working electrical outlet and press the power button. A possible BIOS failure has occurred; the computer is in the recovery mode. Run the BIOS Recovery utility, wait for recovery completion, and then restart the computer. A possible processor failure has occurred. Reinstall the processor and restart the computer. Memory modules are detected, but a memory failure has occurred.

• If you have one memory module installed, reinstall it and restart the computer. (see "Memory" for instructions on how to remove and install memory modules.)
• If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
• If available, install properly working memory of the same type into your computer.
• If the problem persists, contact Dell.

A possible graphics card failure has occurred.

• If the computer has a graphics card, remove the card, reinstall it, and then restart the computer.
• If the problem still exists, install a graphics card that you know works and restart the computer.
• If the problem persists or the computer has integrated graphics, contact Dell.

A possible floppy or hard drive failure has occurred. Reseat all power and data cables and restart the computer. A possible USB failure has occurred. Reinstall all USB devices, check cable connections, and then restart the computer. No memory modules are detected.

• If you have one memory module installed, reinstall it and restart the computer. (see "Memory" for instructions on how to remove and install memory modules.)
• If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
• If available, install properly working memory of the same type into your computer.
• If the problem persists, contact Dell.

Memory modules are detected, but a memory configuration or compatibility error exists.

• Ensure that no special memory module/memory connector placement requirements exist.
• Verify that the memory modules that you are installing are compatible with your computer.
• If the problem persists, contact Dell.

An other failure has occurred. This pattern also displays during System Setup and may not indicate a problem.

• Ensure that the cables are properly connected to the system board from the hard drive, CD drive, and DVD drive.
• Check the computer message that appears on your monitor screen.
• If the problem persists, contact Dell.

After POST is complete, all four diagnostic lights turn green briefly before turning off to indicate normal operating condition. None.

Hello,

This problem is usually caused by a failure on the motherboard. It is repairable if you can solder. The repair involves replacing 5 small parts. Look over this article on our web site at: http://www.ccl-la.com/blog/index.php/dell-optiplex-gx620-motherboard-repair/ The article show what to look for on your motherboard to determine if your board is affected. The capacitors should be flat on top, any bulging indicates failure.

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

Hi,

• Turn the machine off and unplug from power.
  
• Locate and remove the CMOS battery.
• Disconnect the hard disk from power
• Leave it like that for a few minutes and the connect everything.
• Start the machine now.

Worked for me,hope it does for you.Thank you!

If you are saying the Monitor says No Signal, then more than likely the Video Card in the computer is bad. Try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor does the same and displays No Signal, then your video card is bad. If the Borrowed monitor displays and works ok, then your original monitor is bad.

On a desktop it is easy because you don't have many parts to remove. A digital camera might help to remember where things go. Just remove the case and lay the laptop on it's side. Start unplugging the connections that run from the Power Supply to the motherboard and devices such as the hard drive and DvD Drive. You might have to remove the Power Supply, Hard Drive, Cd Drive, etc if they are in the way of getting the board out. There will either be screws that hold the motherboard to the case or there will be latches used to hold it to the case. Once removed, just lift the board out. Remember to take your memory, CPU, Heatsink and CPU Fan off the old board and put them on the new one. You will need some Thermal Paste to apply a fresh coat on the Cpu and HeatSink to keep the board from overheating.
