Processor: Intel Bloomfield i7 920 2.67GHz Quad Core
Graphics Card: EVGA GTX 780 FTW ACX Cooler Superclocked
Motherboard: Alienware X58 Motherboard (Outdated motherboard I took from an old computer from 2008)
Hard Drive: 500GB HDD Western Digital
Power Supply: Corsair 1200AXi 80 Plus Platinum
CPU Cooler: Corsair H80i
RAM: AVEXIR (3 x 8) 24GB RAM
Monitor: ASUS PB278Q 27'' 2560 x 1440 Resolution
Operating System: Windows 8.1 Pro

I started noticing the problem when playing Company of Heroes 2. The game is really graphics intensive. About 10 minutes in on maximum settings, my computer would completely crash/shutdown.

After this, my computer will try rebooting as it always does after a crash, but it would fail for about 5 minutes, trying to turn on but promptly turning off. The cycle would repeat until it would turn back on.

I am guessing it is waiting for something to cool down?

1. I used AMD Catalyst Uninstall Utility to make sure my old AMD drivers weren't conflicting with the Nvidia card.
2. I reinstalled Nvidia driver and GeForce experience.
3. I ran Furmark GPU Torture test and it crashed at around 68 C.
4. I logged my GPU sensors on CPU-Z
5. I ran the Preboot Test on the Boot Settings in the BIOS

The results of my latest crash (to the latest second):

Date: 2013-11-09 18:42:32
GPU Core Clock: 992.9 MHz
GPU Memory Clock: 1502.3 MHz
GPU Temperature: 67 C
Fan Speed: 86%
Fan Speed: 2797 RPM
Memory Used: 970 MB
GPU Load: 99%
Memory Controller Load: 64%
Video Engine Load: 0%

PerfCap Reason: 1
VDDC: 0.984 Volts
12V: 11.77 Volts
VDDC Current: 89.0 Ampheres

Compared to idle:

Date: 2013-11-09 19:13:09
GPU Core Clock: 979.8 MHz
GPU Memory Clock: 1502.3 MHz
GPU Temperature: 31 C

VDDC: 1.033 Volts
12V: 12.06 Volts
VDDC Current: 6 Ampheres
VDDC Power: 5.5 Watts
VRM Temperature: 38 C

I am now afraid that my GTX 780 is damaged somehow and I have loads of questions.

1. How can I tell if it's my Graphics Card that is the problem?
- Any software tests?
- Does the information I stated above indicate anything?

2. How can I tell if it's my Motherboard that is the problem?
- It's an outdated motherboard from 2008
- Can an outdated motherboard like this run a GTX 780 and a 1200 Watt PSU?

3. Did overclocking my GTX 780 damage my graphics card?
- I can't observe any kind of FPS drop once I compare the FPS to my pre-overclock settings
- It didn't crash when I overclocked it a week ago
- I currently have the GTX 780 in factory settings.
- It has never crashed during overclocked settings
- I used EVGA Precision X to overclock and only maxed the voltage to its limits which was +38mV
- I may have increased the GPU clock or memory too high. I went as far as +200 MHz and decided it wasn't good for my GPU due to artifacts showing up.

Please help me!

Thank in advance,

North

My VDDC Current reading is spiking to 73A and yours is 89. That is insane... My PSU only supports a max of 70A on 12V. The card should never approach more than 50 or so on standard clocks like that.

I'm trying to get a 780 guru to answer me, but VDDC current should never spike that high I don't think.

The multiple restarts you are getting is usually a CPU overclock being re-adjusted from failing too I think.
