how to find out why my computer restarts while playing some games.

[birdy370]

For some reason when i'm playing some more "intense" games (dont know how to put it) my PC will just randomly restart. This happens when i'm playing games like Arma 3 and sometimes even csgo. In Arma i cant even be on the game for more than 5 seconds before it restarts.

I dont think it is overheating because when it restarts my cpu is only like 70C (i did a blend test with prime95 and my cpu got up to 100C and didn't restart).

Is there anyway i can see logs or something of the restart to find out what is wrong?

My specs:

Operating System:
Windows 8.1 64-bit

CPU:
Intel Core i7 4790K @ 4.00GHz

RAM:
16.0GB Dual-Channel DDR3 @ 666MHz (9-9-9-24)

Motherboard:
Gigabyte Technology Co., Ltd. Z97X-Gaming 3 (SOCKET 0)

Graphics:
3071MB NVIDIA GeForce GTX 780 (CardExpert Technology)

Storage:
1863GB Seagate ST2000DM001-1ER164 (SATA)
223GB KINGSTON SHFS37A240G (SSD)

Optical Drives:
ASUS DRW-24D3ST

Audio:
Realtek High Definition Audio

And my power supply is Thermaltake Smart 750w 80 plus bronze.

Tier 4 PSU uses lower quality capacitors and failing secondary capacitors would explain the problem, the also tier 4 Corsair CX also has this problem. Do you have another psu you can try?

No i don't have another one.

CPU isn't overheating but GPU and Mainboard are not the same.

First, ensure you have the latest version of your GPU drivers. Download the new driver, completely uninstall the old, restart, close anything that has anything to do with the GPU (Afterburner, etc), then install new driver.

If you've already done that, check the airflow to the power supply. This model does sometimes have thermal issues, so may be heating up and causing your symptom. A good blast of canned air and making sure the intake isn't clogged in anyway (especially if there's a filter) is important.

That said, the stability of the power supply is an often overlooked consideration in high-intensity use cases (gaming, CAD, 3D, etc.).

Bronze is at the lowest end of the stability/efficiency spectrum, and you're running a very high performance processor (and I'll just assume it's overclocked, making it require a more stable power signal). High end graphics cards getting a huge workout along with the CPU may be just enough to take the power supply over the edge so that it's delivered power sine-wave is outside of what the mobo has been told to accept.

If this is only happening during the heaviest of CPU/GPU loads, I would suspect a power supply issue.....even if you're passing Prime and CPU thermals don't appear to be an issue.

Okay, i'll probably go out and get a better power supply and see if it stops.

"Bronze is at the lowest end of the stability/efficiency spectrum" That's wrong. 80plus white is the lowest 80 plus certification. The 80 plus rating has nothing to do with the quality and stability of the unit it's simply an efficiency rating.

Fine:

Bronze parts are at the 'lower' end of the efficiency spectrum, and typically made with lower quality parts or lack features, and therefore tend to have stability issues as you approach their rating limits.....

Better

Still not correct. There are bronze units that use high quality parts and have no stability issues, and there are gold rated units that use cheap capacitors and have stability and reliability problems. The 80 plus certification is not a quality rating.
