Re: Welcome to GIGABYTE Technical Support!
Hello
I've just had a similar problem to this with my son's new build. Gigabyte D3H would work fine if using on board graphics connected to VGA cable but as soon as I put in his XFX 7870 it would either freeze on boot or BSOD saying hardware issue. So I tried one of my 6870's and it did the same thing. I then tried an old 4890 and it worked ok. I tried the 7870 in my machine and it worked ok. So i was thinking it was MB or power supply problems. Got a new more powerful PSU and tried that. Again it would either freeze or BSOD. SO I then trolled through lots of google pages and eventually I managed to get it working. What i did was;
Take out GPU and attached monitor to Internal graphics.
Done a fresh install of Windows.
Updated BIOS to the newest one (F18 i think it was)
In BIOS I disabled all power saving features on the CPU
Disabled internal graphics
Put 7870 in machine
Installed latest Drivers for GPU
Then installed MB Drivers individually rebooting after each one was installed (if a reboot was required)
His machine has been working fine now with the 7870.
Seems it was either a conflict with the internal graphics or the power saving features where stopping the card running properly.
By the way i've NOT re-enabled anything that I disabled.
