After 3 days of digging, I found the fix for the OptiPlex 790 and 990 PCI Serial Port Driver issue which shows as a yellow triangle under Device Manager. This trouble occurs when you upgrade from Win 7 which is fully-supported by Dell on these machines, to the unsupported Win 8 or Win 10. Again, this trouble surfaced because Dell decided not to provide support Win 8 or Win 10 for these PC's. Intel driver detection tools also won't fix this issue. I'd like to give John Makster about 99% of the credit, but his answer was buried in a forum thread that was tough to find. The fix he found for Win 8.1 back in 2014 works perfect for 790 and 990 under Win10.
Procedure: * Download the following Dell driver package, and ignore the warnings that it's older than what you have currently installed: * Don't choose the autoinstall exe package. The package is older, but it contains the correct driver for the PCI Serial port which is missing on your machine after upgrading to Win 8 or 10 * Unzip this compressed Dell file into a folder of your choice. I created a new folder called PCI Serial Driver fix. Do not execute the file package once unzipped * Launch Device Manager and scroll down to the 'yellow trouble triangle' over your PCI Serial device * Open the device and update drivers by pointing to the unzipped folder you just created Voila, trouble solved. The Win 8 and 10 compatible driver is found and updated. Instead of a malfunctioning device, the Device Manager tree now shows: Ports (COM & LPT), PORT (COM1), Intel(R) Active Management Technology (COM3) PS: I have a Dell OptiPlex 790 MT, but this fix obviously works for 990.

PCI Express Serial+Printer. PCI Express Card Serial(DB9M) -Parallel(DB25F). Driver supports Microsoft Windows 98SE/DOS/Linux/XP/2003/2008/32/64bit. QNINE PCIe 2 Port Serial Expansion Card, PCI Express 1.0 x 1 to Industrial DB9 COM RS232 Converter Adapter Controller for Desktop PC with Low Bracket. DTECH 10 ft USB to RS232 DB9 Female Serial Port Adapter Cable with FTDI Chipset Supports Windows 10, 8, 7 and Mac Linux. UGREEN USB 2.0 to RS232 DB9 Serial Cable Male A Converter Adapter.
The same R298379 package applies to both. There are tons of Dell models that work fine in windows 7 or 8 or 10 that are 'not supported'. Optiplex GX620 machines work from MSDOS all the way to windows 10 just fine as long as you update the bios to A11 and use a pentium D 900 series 915 to 945.
Pre 2005 you have issues because the CPU'S do not support NX or CMPXCHG 128 so windows WONT INSTALL on those. 'Officially no, Dell has not listed this system for Windows Vista or Windows 7 compatibility and as such no drivers are officially available directly on the drivers and downloads page.' (Actutally the Vista Drivers were listed but this has become broken) There ARE Vista Drivers. No Windows 7 Drivers from Dell. (Dell Officially Listed this system as Designed for Windows XP/Vista Capable) You will be Much Happier with the Upgrade Result if you Get 4 Gigs of Ram and a radeon 6450. From $39.93 Most of the hardware uses Native Windows 7 Drivers with the exception of the Audio Codec. Thanks, Chris: Yes, I realize Dell can't spend time and money supporting their PC's beyond about 5 yrs.
Obsolescence is the nature of the business because they must compete with mfrs that do the same. Generic or home-built PC's have no such support, but such hardware is not bastardized (customized) for Dell.
