Are you comfortable entering your system BIOS when the computer boots?
You likely need to to set your display defaults in the BIOS. If you provide your motherboard name and model number, I'll try to look up the settings for you.
I don't know the make of the motherboard. I'm not to comfortable with changing the bios. I'm running an AMD A10- 5700 APU with Radeon Graphics 3.4 GHZ 8 gig of Ram
