I even purchased the similar system . The core VGA slot has got no fault and the power supply more power then really what it required. Consorting to me I would advice RMA the mobo into MSI, and they will quickly furnish you a replace. I am having trouble with my audio . initially it shows that there was no audio machine linked . After than I flashed the BIOS and rebooted my system, later some time I am it it demonstrating that the headphones are plug in still there is no outer machine linked into it.
