Graphics card or driver issue?

To start, I have a Radeon HD 7850 graphics card with 2 monitors connected. The primary display is connected with an HDMI to DVI cable and the other is standard DVI.

I have a continual problem with my primary display where the screen will turn black with multiple colored lines running up it in a horizontal pattern as if the colors on the page were dragged to the top. It does not affect the secondary display(which is an extended desktop) but if I disconnect the HDMI cable the same problem occurs on the second screen. This led me to believe it is a driver issue but could it possibly be a fault in the card whenever it recognizes the primary display and malfunctioning?

Also, restarting the computer fixes the problem every time and I have tried updating the drivers to the latest beta build and trying the original released drivers after fully uninstalling the amd drivers.

Im pretty new to this site in terms of posting so I am not sure if this is the correct way to link this but here is a link to a picture of what is happening in case my description was not very clear.

did you have it before/when you first purchased it or is it troubling since recently?

If so, it could be hardware..

However, you can start your PC in safe mode, uninstall the display drivers,

use driver sweeper and remove the drivers completely of its files..

then try installing the latest dirvers..

Since you mentioned that you got it on Xfire, AMD has issues on XFIRE setups... maybe the latest drivers broke something there..

alternatively, you can try swapping the two GPUs off their PCIe slots, i.e. make your current primary GPU as the secondary and your current secondary GPU as primary and try running to isolate the issue..

Have you try to switch the monitors? Make the primary secondary and the secondary primary, without switching cables. If the same thing happens with the second monitor set as primary display maybe this post can help you:

I must have mis spoke. I am not running crossfire. I only have a single card and I have tried changing the displays around amd it is the same issue. I would assume if it were the hardware that it would be a consistent problem but the time between occurences varies dramatically. It could be a month between the problem befor it happens again or it could be tomorrow l.

Also the card was bought new about a year ago

Aah.. So I see that you are running two displays with one GPU.. I think I know what could be the issue..

- the graphic card is not seated properly to the pcie slot.. You can switch off your PC and try to seat it back up..

- the cable is faulty.. Change the cable..

Its one of the two reasons.. I have similar setup at work and these are the only two points where the monitor is having issues..

Just try switching the HDMI and dvi cables to the monitors and if the Issue is replicated in the other display, change the cable.. :)
