OptiPlex 790 guard lock

We have a customer who bought an Optiplex 790 a year ago and continues to have a problem with it locking up. We have changed the settings, will not hibernate or stop the hard drive and also flashed the BIOS to the latest version. All diagnostics have been run, but no problems were discovered. Sell support suggested to reinstall the operating system (windows 7 pro). Has anyone out there experience this problem before, and if so, what was the resolution?

  • OptiPlex 790 Mini-Tower bi-ecrans?

    I have an Optiplex 790 minitower with Intel HD 2000 integrated and i5-2400 video.

    The case has a VGA and Display Port connector, I am currently using the VGA port. I am a student going for a Setup dual monitor and am confused if I can do without having to buy a discrete video card. I read conflicting reports that some say Yes and some do not. Can a kind soul please one way or the other?

    I do not use the PC for games, it's a casual work with video and web browsing. I need mainly two monitors for editing multiple files, scripting, programming, database etc..

    Many thanks, flipper.

    Hi end,

    Embedded video solution of OptiPlex 790 is VGA and DisplayPort compatible at the same time. You can connect two monitors to the computer without adding a discrete card.

    Please let me know if you need further information.

  • Lack of Dell Optiplex 790, PCI Simple Communications controller driver

    Performed a clean installation of Windows 10 Pro on my Dell OptiPlex 790.  Everything went well and all device drivers have been installed except one, the Intel AMT - GROUND device.  The vendor id is 8086 and the device id is 1C3D.  Can help you with this question?

    Thank you.

    -Jim

    It seems that it is the Intel Series driver LAN.  Your computer was never tested by Dell for Windows 10, which means there is no new driver created by Intel, etc., that can work.  You can google Intel AMT/GROUND and see if Intel has a driver for your chipset that can work.  It looks like Dell stopped supporting your computer for Windows 8.0

  • OptiPlex 790 SFF need service tag

    I bought an Optiplex 790 SFF skeleton and found out that it doesn't have a label service all over her. How can I get a serial number for it? I can from Dell?

    Latest version of the BIOS for OptiPlex 790 is here. Serial number shouldn't matter...

    Read and follow the instructions carefully and turn off anti-virus suite first, if you install it in Windows.

    Keep in mind there is always a small chance a BIOS update fails and kill the motherboard. So upgrade at your own risk...

    Assuming that ST has not been removed from the BIOS, you should be able to find by using the free version of Belarc Advisor.

    EDIT: ieee488 types faster as I do!

  • Question of OptiPlex 790 Displayport

    I have an Optiplex 790 and am setting up two monitors.  Two monitors are DVI and VGA inputs.  My 790 has a VGA and Displayport output.  I have the standard VGA cable and it works very well on both monitors.  I also have a Displayport adapter to DVI with a DVI cable.  When I have this hook to each monitor receive nothing.  The monitor is just like it does when it is not connected.  I tested the Displayport adapter and cable on the anther, put in place that works fine so I know the cables work.  In the video settings, it is only showing that I have a monitor.  Any help would be great.

    Thank you

    I reinstalled my video driver. But I also had a bad adapter Displayport to DVI.

  • Power supply Dell Optiplex 790 SFF cycles power on and off when it is plugged

    My new to me SFF Optiplex 790 does not start - pressing power causes a switch to send amber for a few seconds, the 1 + 2 diagnostic lights shine briefly, and then the system turns off. But wait... with power plugged in, it will try to restart every 10 seconds or until I have unplug the unit.

    System lasted about 30-40 minutes when I tested it, but it starts then power cycling.

    Power supply passes with built-in 'green light' regardless of any internal or external devices connected. I bought a sweater 'work' PSU, no change.

    Ideas for testing? System is stock, no mods or upgrades of what I see.

    Hello

    This system is out of warranty period so that any replacement of parts will be payable. That's why we can help you with the replacement of the part by sending the request for quote for parts and service or, Alternatively, you can buy the part of any provider of local service from dell.

    Serial number of the system also has information on the customers system so donot share it as a public message, send it out via private only message.

  • RAID0 en Dell Optiplex 790

    Buenas tardes!

    Estoy queriendo usar una Optiplex 790 como backup servidor, por lo that I need armar discos in RAID 0, y queria Saber TR are posible. Porque por lo than Biogen verificando via not web, none are posible.

    MUCHAS Gracias!

    Hi GFurlani,

    It is my understanding that the Intel Q65 chipset does not support RAID. If you need to add a separate controller card that supports the data disks in a RAID.

    Good luck!

  • ESXi install on dell optiplex 790

    Hi experts,


    1A tried to install Native Vmware Esxi 5.1 OS on Dell Optiplex 790, reported Installation Wizard not found supported network cards.

    2. I tried Esxi custom Dell installation 5.1 on the same area, then received the same error message.


    sounds like network drivers is not included in both of the Esxi Images, any idea on this issue.


    Error message 'no network adapters detected' when installing ESXi on Dell PowerEdge servers 12th generation - Dell Dell TechCenter - TechCenter community.



    Dell optiplex 790 got the intel pro 100/1000 cards.


    Even when I installed RHEL, it's the same thing, but fortunately RHEL does not stop in the Setup Wizard if the card is not supported. After the Installation of OS RHEL. I installed the e1000 driver. It works very well.


    VMware should have the same opportunity to install drivers after installing ESxi OS.




    If you do not have a suitable driver for the specific NETWORK card package, you can use Image Builder to create a custom ISO Setup / CD. Take a look at http://www.v-front.de/p/esxi-customizer.html , which greatly simplifies this task.
