7950 is not compatible with 280x , it is only works with 7970.I also have the same problem with 7950 when I try to connect it will not work but 7970 works fine.
Did try the device manager uninstall and it resulted in all the graphic cards named 7900 series and everytime i operate cgminer, vertminer they crash due to the driver crashing, this might work if all the cards are the same model. Are your mining rigs the same card model, so one rig only has 280x the other rig only 290s. Will try downloading the latest beta driver.
so all cards were recognized? no yellow triangle? if thats the case you need to automatic update each 280x one by one (sometimes only once) in the device manager. Yeah it did not give and yellow triangles but it crashs really easily. When I try to update 280x by pressing automatically update it says it is up to date.
you dont need these drivers for windows 8.1 only windows 7

Hey guys;
I have a 6 card rig which is made of 5 280x and one 7950 connected to an asrock h81 pro via usb power riser. Am getting an exclamation point on the 7950 with code 43 notifying me that it can't detect it. I removed the card, uninstalled the driver and reconnected but it came as Microsoft basic adapter. Tried to install the driver to the 7950 by itself but the install update jams and i have to restart it. Tried this http://www.gobitgo.com/articles/1002/How-to-Mine-with-6-GPU/ but as I said the install update jams. Any ideas how to fix this?
go to device manager display adapters go to the 7950 uninstall and unistall driver and let windows update the driver for you should take a couple minutes. this will only work on windows 8.1 i have 3 of these boards and had same problem windows 8.1 did the trick.

Did try something similar I went to device manager and uninstalled the 7950 and deleted the driver of the graphics card, but if I press search for hardware changes if gives the same thing, the name of the device with an exclamation point beside it. so as a second try I shutdown the pc removed the card and uninstalled and deleted the driver in device manager. shut down the pc and reconnected the graphics card. when I went into the device manager it named it microsoft basic adapter. But I will try to do as you said and let windows update to install the driver. if this doesnt which hopefully it will I will try to install the latest beta driver 14.1 beta as I heard from some that it helped solve their problem. if not
will try install the 12.6 version even though I have a win 8.1 64bit os and the 12.6 supports til windows 7.Posted From bitcointalk.org Android App
