Hi, I know my stuff is old and out dated but I'm hoping someone can help me. I have dual Radeon 5670's GPU's on a alienware aurora windows 7 and i7 processor. I have had trouble with crashing when I use both graphics cards so I have usually just used one. I have been noticing my fps slowing in iracing so I tried the other graphics card and disabled the one I usually used and the fps sped up. Cool. But when I go to start up the computer I get a blank screen no signal. I'm using a crappy little vga acer monitor. So to get it to work I have to plug the monitor into the graphics card I thought was disabled and the display works but says no graphics card detected and it looks like its in safe mode or something. So I have to go thru the whole process of enabling the crappy card and then disabling it and plugging into the good one. I am not a big tech guy so maybe I'm missing something simple. Thanks for your help.
