Hello anandtech!
I recently upgraded from a core2duo/4870 to ivy bridge/7870/Z77X-UD3H gigabyte. Should mention a seasonic 750W PSU as well.
Everything was going great until I tried to start the computer. No screen whatsoever, on bios or OS. I used the intel 4000HD to get windows installed and get up and running.
I tried installing AMD drivers for the video card but it would have problems during installation. Basically, it wouldn't detect the video card which makes sense because the card doesn't show up in device manager either.
SO, troubleshoot time. I first tried to disable the onboard GPU and that left me with an unusable computer, bios reset (BTW, I'm running a gigabyte Z77X-UD3H motherboard). I try a few other bios options like forcing PCI-E to be the default all to no avail.
I then set up my old motherboard with just a CPU and RAM and the video card + my old power supply. The motherboard booted to the bios screen and I could see it which is more than I am getting on the new motherboard. So the video card works in the OLD motherboard but not the new one.
That would lead me to understand that perhaps the motherboard is faulty. I tried the other PCI-E slots which did not work. I THEN tried my old 4870 (bless it, such a god buy) and it works flawlessly in my NEW motherboard. I am currently playing Diablo 3 and BF3 on it.
SOOOO, the question is, am I missing something. If I return the card to where I bought it they will charge a 15% restocking fee if there is nothing found wrong with the card. This would be alright if it worked in NOTHING but it worked in my old motherboard.
Do you guys have any insight as to what might be the problem? Have any of you ever come across something like this before. Any help is much appreciated.
