first off check the mb bios rev. the newest rev is f14 that i found. the bios rev will be on the first page of the bios screen. make sure your mb has all of the bios patches. with the ram make sure xmp profile is turned on and run cpu-z check that the ram in windows is running at it rated speed and voltage(the spd tab will show you your ram rated speeds). make sure you have the newest intel chipset driver install. the last issue could be that the low end power supply can output the voltage needed for the gpu. one issue if it not power then it could be that the gpu fan not ramping up to keep up with the heat. try running msi afterburner make a fan profile. and check that the gpu fan will spin up to it max speed. if you have a mini or small case if you think it heat issue take the side panel off. I would also run hardware monitor to check your cpu and gpu temps..post them up here to see if there getting to hot.
