Jan 5, 2012 - Solved: Installed new OS and then installed the drivers from driver disk in correct order, however, the PCI Simple. Missing PCI Simple Communications Controller Driver. I has the same problem, Your link is the solution. I tried the Vista drivers on Dell Driver downloads site and after attempting to install them, I get an error saying that they are incompatible with the OS. I found these on Dell.com for my Optiplex 760 running Windows 7.
Hey guys, I have an Optiplex 980 which I digged up to sell and I had an extra graphics card in the computer. I don't have the exact model of the graphics card here right now, but the thing is that these low profile cards come with a special DVI-looking plug which requires a cable that splits into 2 regular DVI ports. I do not have this cable so the plan was to pull out the card so BIOS wouldn't auto-disable the on-board VGA or let me use onboard display port. However the computer boots up with diagnostic lights 2 4, which means graphic card failure - even without the graphics card in the computer. Anyone have ideas on what to do??
Not sure if I need to enter bios to enable the onboard graphics card. But in that case I have a problem lacking the weird-DVI-plug-to-two-DVI-ports-cable. Finally got around to testing this with no luck. Tested the following: -Removed CMOS, held power button to drain power, waited 1 minute or so and put it back in.

Did several times -Removed RAM, tried starting with only 1 ram chip. Tried both chips -Tried to insert graphic card in another slot -Tried with and without graphic card inserted Regardless I get the 2 + 4 graphic failure diagnostic lights.
This computer was working fine the last time I had it rigged and there's no way BOTH onboard VGA + graphic card is broken. Any other suggestions guys? Guess I will just strip it for RAM & SSD, sell them - then throw the d.n box out the window Hello, I picked one of these Dell 980's in the same configuration, i7 8gb ram with dual radeon 3450 cards with the DMS-59 connections. From the service manual I don't believe onboard video was an option for the i5 & i7 models. Both the onboard VGA and display ports had black plugs with the no symbol on them in my system. I eventually broke down and ordered the $4 splitter on eBay.
Works well for me. I'm wondering if I can hook up a second splitter and run 4 displays​?
