So I've been messing with the wife's rig for a couple weeks now, replacing pieces, trying to get it to run. At this point, the only thing that ISN'T new, is the video card. Everything that is in it, I checked for compatibility on PCPartPicker.com, everything was good to go. I get everything hooked up and double checked, go to power it in, and it's doing the same thing it did when it originally didn't want to fire up....hit the power button, it will light up and spin the fans for maybe half a second, then it quits, and won't do anything, unless I turn off the power supply, then back on again, hit the power button, same thing... At this point, I'm not sure what else to try. I read some posts that the B350 boards aren't the greatest, but it still compatible with the Ryzen 7 1700x, which is in it (according to PCPartPicker). It's hooked up to a new 500gb SSD, a new 750 PSU, new SATA cables, and yet it STILL won't boot up. I really don't want to have to pay to take it in...I've built several rigs in the past, but this is the first time I've had this much trouble with one before. Any help is appreciated.
