I have a MSI A75MA-G55 motherboard and have been using the GPU on my AMD A8 APU. Recently though I decided to upgrade my GPU and got an EVGA GForce GTX 750Ti card. After getting it installed my motherboard stoped posting for some reason. All I get is a "_" in the top left corned and B2 in the bottom right corner and nothing else. After a while it will beep like its trying to restart, but doesn't actually do anything different. If I take the card out and start it back up things go like normal without problems.

Thinking that the issue might be a conflict between my on board GPU and the new card I went into the bios to see if I could find any settings to allow the switch to happen. I found an option to dissable the on board GPU and thinking that would fix things went ahead and did that. So now I have the problem of not being able to reenable it.

So as may or may not be made clear by the above I'm A little out of my depth here and would really appreciate any ideas or suggestions I can try. Thank you all in advance for your help.
