Brand New System Freezing

I've just built a new system, i5 6600, Asus Z170-A motherboard, new ram (an 8 gig DDR 4 Corsair stick) and a new SSD. I've got windows 7 installed here, but the system is freezing up really frequently when gaming (World of Warships to be specific.) I'll be playing and within 10 to 30 minutes the computer freezes, the screen image is stuck on the last rendered frame and the audio plays a loud sort of buzzing noise (I have no idea what to make of that, if it's cycling a sound super fast or what.) I can't do anything except hit the power button and restart the system.

I've checked the windows Event Log, but nothing jumps out at me, and I'm at a loss. Most of the parts are new (reusing a case, PSU and optical drive, plus a Gigabyte 970 vid card that's maybe a year old only) I'd appreciate any help. Thank you.

I'll give it a shot. Just wondering though, now that I think about it, the power supply is old. Like eight years old maybe? Old enough I don't remember exactly when I got it, and I'm pretty sure I put it in the backup computer I pulled it out of because it was acting up. Anyway, I'll give the ram reseating a shot and report back.

I switched out the video card (a 970) for an old 460 I had around, and made sure to pick a different set of drivers as well. It hasn't helped, the system is freezing in windows now, doing regular things like web browsing. I'm not sure what else it could be. The only other parts that aren't new is a hard drive (used as a backup drive, not the system drive), an optical drive, the sata cables for the optical and backup hard drive, the liquid cooler (a Corsair H-50), the various USB devices plugged into the thing, and the monitor. I just don't know and I'm out of ideas. :(

I thought it might be heat too, so I went through and checked all the fans, and checked temperatures. while gaming my gpu got a peak heat of 60c, hanging at 54c most of the time. My cpu cores didn't get above 48c. From what I understand these temperature readings aren't bad.

I also tried disconnecting all the usb devices and using a different keyboard and mouse, just to eliminate any usb device issues as the cause. make no difference what I use for usb. Also downloaded some utilities to check on health of my hard drives, and they checked out fine. Also ran memtest86, 8 passes and no errors. I don't know what could be left, it seems like I've ruled out every possible part, unless I'm missing something. But the problem is still there, I just froze my system within the first 5 minutes of a World of Warships battle. Not even numlock on my keyboard responds when it freezes either.

I found a thread about skylake processors having freezing issues over on the UK site of Tom's. They suggested disabling CStates in my cpu. Long running discussion that somehow came to something so obscure. So far it looks promising. I haven't run long enough to know for sure either way, but my system is more stable than it was while gaming, no crashes. So either random luck setting a new uptime record in World of Warships, or it's fixed. Another day and I'll know more.
