Hi guys! I'm having trouble using both my graphics cards at once. All my drivers are updated and the graphics cards are both detected and utilized via the AMD crossfire enable option, but i have some very annoying problems. One is that every time i log on it asks me to enable crossfire which i'm sure isn't right. Most importantly when i'm playing my games there is no improved performance and very distorted glitches happen during gampeplay to terrain and mostly HUD elements. Also when playing highly advanced graphics games such as Skyrim my computer eventually crashes and and throws out a black screen with a continuous noise coming from my monitor. Sometimes when i turn on my computer and log in it tells me it couldn't find an operating system. I have tried to figure out the problem via trial and error and have concluded its not the graphics cards or connection to the motherboard. I also have two crossfire cables and i'm pretty sure that both of them wont be faulty. I have only had my PC for a few weeks and this problem began on day one. Thanks for your time!
