G3258 4.2 GHz causing hard booting/BSODs?

I recently built a new computer:

Pentium G3258
8GB DDR3
AMD R9 290X reference
Corsair RM650 PSU

Now, before the Corsair I had an older 750 watt PSU and whenever I would run Furmark my PC would immediately hard boot. Same with Unigen Valley and in any graphic intensive game.

So I bought this RM650 used from someone who had the same GPU. Now I can run Furmark quite easily for an hour (longest I've tried), however, it has still hardbooted twice after an hour of playing Assassin's Creed 4.

It also gets a BSOD randomly in some games and says there's an uncorrectable hardware issue. I looked at the log and it says there's an issue with a processor core.

Do y'all think the rebooting is tied into the BSODs? 4.2GHz at 1.275 volts is the highest my GPU will overclock without locking me out of my BIOS. I've run a few CPU benches and it hasn't seemed to come up with anything. I've also done memchecks so it's not the RAM. I downclocked to 4.0 to see if that helps.

I just...really don't want to buy another PSU. This one should be consistent and powerful enough to handle this setup. This is so frustrating.

Undo your cpu overclock and see if the problem is still there.

What did you do to test your cpu overclock for stability?

I just ran Prime 95 for a few hours. I'm going to try it again before I go to bed for around 7-8 hours.

Prime95 doesn't mean anything. You need to test games as well. If it hard boots it isn't stable.

Just back if off to 4Ghz & forget running Prime.. Just try your games. Your problem should be gone. CPUs aren't all alike.

listen to burpo. you just might be super unlucky and got a bad chip is all.

Would it be safe to run a CPU and GPU stress test at the same time to rule out power consumption/PSU problems? Or would going too long harm my computer?

But why would it shut down instead of BSODing?
That's a good question. We can't immediately finger the CPU, though reducing the CPU clockspeed to stock would be a good place to start. I recommend doing so without lowering vcore. Keep power consumption up while clockspeed goes down. If that doesn't stabilize the system, you should pull the video card and try running games off the iGPU (ouch) for a bit, to see if that doesn't stabilize the system. There may be a problem with power delivery somewhere, but at the moment, it's impossible to nail down exactly what's going on. It could be a motherboard problem, or it could be a problem with your video card.

I just couldn't get my G3258 stable above 4.0, even with 1.300v. So now I run it at 1.200v, but even then, it seems to crash / reboot about once every two weeks.

With how cool it runs, I'd personally just go all out and push it to 1.35V
