Here's my system specs:
AMD FX-8350 (eight core) 4.0 ghz
Asus M5A99FX Pro R2.0
ADATA XPG Gaming 2.0 16gb DDR3 2x8Gb 2400 MHz
2 x MSI AMD Radeon HD 6790 Video Cards (Crossfire)
WD 600 Gb Velocirapter (System)
WD 600 Gb Velocirapter (Work Disk)
WD 600 Gb Velocirapter (Flight Programs)
Ultra Gladiator Mid Tower case (case fans replaced with Cougar Vortex PWM fans)
Antec Cooler H2O 920 (2 x fans replaced with Scythe Gentle Typhoons)
NZXT HALE82N Series NP-1BN-0750A-US 750W Power Supply
Windows 7 x64 Ultimate
I've been running the crossfire for about a month now. One of the Radeon cards has 2 x 6 pin power connections (840 clock) and the other one has 1 x 6 pin power connections (it's an OC model 920 clock). Got a new monitor today and wanted to do some house keeping. The 840 clock Radeon was the original one installed about 6 months ago. I uninstalled all the AMD Video drivers (Control Panel, reboot, Driver Fusion, reboot, search for any leftovers, JV16 Registry cleaning).
When I got it back together, plugged in the new monitor (HDMI) and booted the system. At post, I got the 1 long and 3 short beeps -"no video device installed". Removed the Crossfire bridge and power cable from the second card. Booted, went into Windows, checked driver in Device Manager (Windows standard VGA) - all ok. Shut down, removed power cable (x2) on 1st video card, installed HDMI on 2nd card, power cable and booted - all ok. Reconnected both cards, Crossfire bridge, HDMI cable on 1st card, booted -"no video device installed". Tried HDMI cable on 2nd card - "no video device installed".
Went back to 1 card in system and installed Catalyst 13.4 (13.9 messes with FSX) on each card - individually runs fine, both connected same problem. Reinstalled the card in the original positions - same problem.
I think I've run out of options - where do I go from here (thinking about a new card - NOT Crossfire - and...maybe...not AMD...
