Overheating AMD CPU and Windows automatic repair crash

[freshmootz]

My gaming machine is suddenly heating like crazy. Right now I'm in the bios and I'm reading the temperature at 185.9F.
Recently I added a new video card (Nvidia gtx 970). Then the problems began. I have the right power supply (Antec 500w) to run the card. I checked the cooler and it seems Seated properly. It crashes right at 185F.
Now when it goes into Windows boot up to loading the automatic repair screen it crashes before I have a chance to go anything.
Any ideas?

put the old video back in.

I did that. Still overheating. I'm guessing the CPU stock fan/cooler just sucks and I need to replace it. I'm certain reseating it will also? Any suggestions on what buy?
