Hi fiqurez
🙂Well I'll state the obvious...that we all have ASUS hardware here so not many will have a great idea about MSI motherboards :confused::o
Having said that there are plenty of troubleshooting steps in common.
Have you got the latest BIOS for your board? But be careful make sure it is the latest for your OS too...the very latest are recommended for win 8 only for example....can you get into BIOS on the screens? I would start simple and try connecting only one monitor to start with of course. And how are you connecting....correct cable etc.
You got GPU seated correctly and all the power connectors properly seated?
