I've recently did a bunch of upgrades to my computer including adding more RAM and a new GPU (1070) among other things a few months back. Shortly after installing the new graphics card, my computer wont boot Windows after its been sitting for a few hours. It will just go to an empty black screen. If I perform a hard reset, it starts right up and there are no problems. But once it sits for a few hours with no power it will do the same thing.

I've tried updating my BIOS on my motherboard and that didn't do anything. Now i'm at a loss of what else to do. Any suggestions? Thanks in advance.
