I just bought a Gateway DX4380G-UW308 with a A6 5400k Trinity APU with built in graphics. It had an open PCIe so I put a Radeon 7770 in it and upped the PSU. But now my computer doesn't recognize monitors if they're plugged into the Motherboards HDMI or VGA. And under manage devices it only shows my 7770 under display adapters. It doesn't show the orginal driver for the APU.
So my problem is when I restart the computer or turn it on the monitors don't automatically turn on. I have to unplug one of them and then plug it back in for them to recognize the signal. I have windows 8 and when I try to restart it into BIOS they wont turn on even if I plug them back in. I have to manually shut the computer off and turn it back on to boot into windows then unplug/replug a monitor in for them to work. This is driving me crazy and idk what to do. Under Windows setting it's showing my main monitor as #2 and my secondary monitor as #3 but no #1. Under AMD Catalyst it's configured correctly but not under windows.
I can't change the numbers of the monitors and cant get into BIOS to set my graphics card as primary video. And now my orginal video outputs built into the motherboard aren't working at all.
Please help! Thanks ahead of time!

This worked for me!
I'm have the same problem, I found the link below going to try it later on today. I saw the secure boot in the BIOs screen. Hope this fixes the problem.
No video at POST with new video card in Windows 8 prebuilt machine?
If you have just installed a new graphics card into a prebuilt system with Windows 8 installed on it and get no Video at POST or a beep code, assuming the card has enough power and is properly seated with the necessary power connections, a common cause of this issue would be a conflict with Secure Boot on UEFI motherboards.

I have no solution same problem same computer gateway (dx4380g)different graphics card. Installed radeon 6570 plug in monitor, no signal, there is no option to disable on-board graphics in bios or anywhere. The card works when I plug it into my old Gateway. Can I flash a generic bios to my computer to maybe solve the issue?
I searched high and low, and even found settings for their bios - but nothing to disable the onboard video and/or update the bios.
In some of the other forums, clearing the CMOS settings (with the jumper or removing the battery with power off for 30 seconds), allowed the bios to automatically configure the card.
That is all I could find on it...

I just went into BIOS and there was no option to disable the onboard video, there was no options that had anything to do with video only sata and LAN. IDK if it's different for windows 8? but I tried disabling the onboard graphics on Device Manager then shutting down, installed the card, then rebooted and the monitors didn't come on automatically I had to unplug/replug again for it to recognize the signal from the desktop.
