A:Answer The socket on the motherboard is an AM3+, so you can only use cpus that fit into that socket. No Intel chip will work as AM3+ is an AMD chipset, and the Ryzen uses AM4. I replaced my cpu with an AMD 8350 Black Edition, which works great. As for the PSU, I couldn't tell the wattage, but it should be enough to power most any rig (unless you are looking at multiple gpus. The reason I went with the AMD 8350 was it had the same wattage as the 4350 that came inside. So no worries about power there.
I'm not sure what issues you are having, or if you are just wanting to upgrade, but the issue I had with my rig was the graphics card, it was garbage and kept crashing the computer. I replaced that with a Nvidia GTX 980 from an older rig, and all of my problems went away.
