For your  Optiplex 780 problems make sure you have the latest BIOS update

www.dell.com/.../DriversDetails;fileId=3270400708&osCode=W732&productCode=optiplex-780&languageCode=EN&categoryId=BI

The Optiplex 780 had the latest A15 BIOS when Windows 10 was installed.

Dell is no help:

"Product not tested for Windows 10 upgrade

Dell has not confirmed that this product can upgrade to Windows 10. Some drivers, firmware, applications, and connected devices may not work as you would expect."

The Optiplex 780 PC has only 4GB Ram and originally used x86 Win 7 Pro. Now it has x86 Win 10 Pro. And runs poorly. The PC is 4-5 years old. I wonder if it would be worth it to add memory and convert to x64 Win 10 Pro. Maybe the best option is to revert to x86 Win 7 Pro.

The sound problems with the Optiplex 9020s and Precision 2800 were solved by right clicking on the RealTek sound driver in device manager and choosing "update driver." I do not know where Windows obtains the driver, but it cured the sound problems. Why didn't the Win 10 installation program install that RealTek driver? Maybe it's only been available in the past few days.

Go into power settings and set for high performance.

Then go into advanced power settings and set the HARD DRIVE SPIN DOWN time from 20 min to 480 min,

Then Set the display shut off to NEVER

Then Set the sleeps mode to NEVER.

Several Upgraded systems hang with a black screen and must be forced off.

Once you remove all the narcolepsy its stable.

Thank you for the suggestion.

Hi... I upgraded to Win 10 from Win 7 on my Dell Optiplex 780 (x64) and the big issue is the onboard audio is gone and Dell Website clearly states it's not providing Win 10 audio drivers. Have tried a number of things but no go, no audio. And yes, the system is a tad slower. What *** is that the kid's PC's are all Dell 780's. Hmm.. Upgraded my Acer Veriton also but with no issues!  Rolling the 780 back to Win 7 as performed better, will have to upgrade again.. eventually. Having played around with Win 10, I do prefer Win 7 over Win 10.

Installing the 32 bit or 64 bit VISTA/7 driver gets the audio back.Same thing is true for the video if you are using onboard.

Hey,

I know that I'm replying on an old post but I have this problem. i did the upgrade to win 10 but reverted it after a couple hours back to win 7 pro (I just wanted the machine to be registered with the free win 10 key if I decide to upgrade later on :p) but I had some problems so I did a compleet cleen windows 7 professional install. everything works just fine except windows update. It can't find any updates wich gives some annoying problems like .NET framework not installed and... Does anyone know a sollution for this problem? i tried resetting/reinstalling windows update, i tried reinstalling the complete windows again on a different drive so far nothing works.

specs 

win7 professional 64bit

intel q6600 (overclocked to 3ghz but this never gave any problems before)

16gb ddr3 ram

128 gb samsung ssd

500gb western digital hdd

I struggled with 780 MT drivers not installing for quit a while. The assumption was that sound was enabled by default. Not true for some reason after new installation of Windows 10 64bit from an Enterprise CD. Turned out in the BIOS, under Misc Devices, "AUDIO" was unchecked. Simple fix to a frustrating issue.

I know the topic and old , but so I ocmo others can benefit from this solution I could find .

First download and extract the latest version of the driver for windows 7 .

It needs to be installed manually ,

In device manager , Open sound drivers , see and games

In option HIgh defitinion audio, Right-click , update .

Search the driver manually and select the option to allow you to choose a list of drivers and devices on the computer.

then seek the ADIHdAud file within the R228257 \ amd64 \ folder view

Choose SoundMAX Integrated Digital High Definition Audio

Okay, your sound driver is installed.

Our 780 pc haves Win81-64 clear installed and works fine, all devices are installed.  This works in principal partition 150GB - 120gb free 4gb ram-

Now Im updating to Win10-64 but with the usb based media install, the error 0x8007025D 0x2000C appear some times around 13%. Take No_keep app and configurations, disconnect all usb devices, disable firewall, run defragmentation etc etc and no success. What can it be?

Solved - The 0x8007025D 0x2000C error was solved by creating again the Win10 media, using the newer MediaCreationTool from Microsoft, the old usb media was Win10-june2016 and the new is oct2017.
