Let me start by saying I've been building computers since I was little. It has always been a hobby. I've changed graphics cards in the past without issue. But this time I'm stumped.
OLD: AMD Radeon x800 xt
NEW: AMD xfx r7 370

I am upgrading my video card because the windows 10 update says my current card doesn't have a digitally signed driver and it won't install the driver for it. Using the generic driver I only get 1 monitor going via vga. Normally 1 is vga and 1 is dvi. New card has 2 dvi so I plan on using that for both now.
Trouble is, I installed card, attached both pci power cables, pressed power and all I get are fans and lights. It never makes it to the bios beep.
I have a 1 year old corsair power supply 700watts, no issues there...
I have tried both pci slots. No go. Windows already removed the old driver when it upgraded so only generic Microsoft driver is in use currently. So I don't believe it's a driver issue.
Motherboard is bout 2 years old, gigabyte brand (GA-Z77-D3H) running an i5 @ 3.6ghz.

I've reverted back to my old card in the mean time. It's been a while since I've done upgrades like this so I think I'm forgetting something.

Any help is appreciated.

An assumption was to blame. I assumed that because my motherboard wasn't too old that it had fairly new bios. Turns out, it's bios version was so old it wasn't even listed on Gigabytes website anymore. Once I updated that I had to set the graphics setting to PEG (Pci Express Graphics) for it to function correctly.
