so i purchased a Radeon RX 480 4g OC edition last week and it came in the mail today. i hooked it up to my custom windows 8.1 system, three monitors, cx 600 corsair PSU, i5 cpu, and 4g ram.
well once i got the pc booted up i noticed that only my center monitor was working. i checked the connections and all three were properly connected. i figured it was just that i didnt have all the drivers installed yet so i inserted the disk included with the GPU. i installed the programs contained and it asked me to reboot the computer. i did just that and still only one monitor was working. i tried booting up skyrim to see if it was atleast functioning as a GPU, however it wouldnt even run it on low settings for more than a minute before crashing from the lag. maybe i still havnt installed all the drivers yet, i dont know. this is the first GPU ive tried installing. i have rebooted the computer with only one monitor connected at a time and it will work on all three as long as only one is plugged in at a time and i restart it
