Hey guys,

Recently purchased (couple weeks ago) a Sapphire HD Radeon 7790 because my new Nixeus VUE 30 kept causing the Radeon 4850 to crash. Realized the new 7790 could run three monitors & just happen to have three. The folks @ sevenforums told me Display Fusion was a must.

Yesterday I installed DF & set 3 separate wallpapers from deviantART,very nice - this was on a standard user account & no problems. This morning while on the Admin user decided to go for it & put up a wallpaper than spans all three & my PC crashed twice in the following few hours.
System Dump indicates Probably caused by : atikmdag.sys ( atikmdag+23c5c) which I'm pretty sure is the driver for my GPU. When installing the new Sapphire 7790 I used AMD Catalyst Un-install Utility & Driver Sweeper to clean out old driver files. Then AMD Driver Autodetect & updated to the most current.

Have had no problems until I tried spanning all three this morning & since reverting back to Windows Desktop Background no problems.

Watching a youtube video on Nixeus during one crash but not the second time, just IE, Chrome & Word running. Sapphire TriXX too but I've had that up for a week or so without any issues. AMD Catalyst of course.

Dell 3007 & Nixeus both connected Dual DVI & Dell U2412 via displayport.

Any ideas, tweaks thru DF or more info I should provide?

Thank you

Just a single image, haven't yet attempted loading random wallpapers. I suppose it could just be coincidence that my computer crashed a couple hours after loading the triple monitor wallpaper. Has not crashed in three days since.

This morning however after bootup the Display Driver had crashed, no BSOD just the driver.

So I again ran AMD Catalyst Un-install Utility & Driver Sweeper (CCleaner too) then decided to try a different driver. @ AMD there is a specific Driver just for the Radeon HD 7790 PCIe & I was temped to install that one last week but auto-detect downloaded the latest version for all Radeon HD 7xxx series PCIe.

AMD has released a specific Catalyst™ Performance Driver for the AMD Radeon™ HD7790 graphics card for both Windows® and Linux based systems. This Catalyst Performance Driver can be downloaded from the links below.

Update
◾The Catalyst™ Performance Driver for the AMD Radeon™ HD7790 graphics card for Windows based systems contains an update that resolves Corruption in Tomb Raider with TressFX enabled.

This version looks to be an earlier version than the other:
Previous Display Driver = 12.104.0.0000 & Previous Catalyst Control = 2013.0328.2218.38225
Current Display Driver = 12.101.2.1000 & Current CCC = 2013.0416.1149.19347

So will give this one a shot, see what happens.
