Hi everyone,

I built a new rig a year ago and I've been dealing occasionally with mysterious crashes that lock up the machine and then cause it to restart. Basically what happens is that randomly while playing a game, my rig will lock up and go to a solid-color (usually just black) screen, the d-sub icon appears, sound loops, then after a second or so of nothingness, it reboots. After it reboots, I log back into the game and my PC is fine and doesn't crash again. I have been keeping my windows and video card drivers up to date since the machine was initially purchased back in June 2014, and I'm just at a loss as to what's going on or how to fix it. I thought my card was overheating, so I put in 2 more 120MM fans right on top of it and still no luck. I don't think it's overheating. Happens no matter what game I play. My specs are below:

EVGA 04G-P4-2768-KR G-SYNC Support GeForce GTX 760 4GB 256-Bit GDDR5 PCI Express 3.0 SLI Support SC 4GB w/ EVGA ACX Cooler Video Card
G.SKILL Ripjaws X Series 16GB (2 x 8gb sticks)
Intel i5-4670 3.4Ghz
ASUS Z97-A LGA 1150 Intel Z97
Samsung Electronics 840 EVO-Series 250GB 2.5-Inch SATA III
Windows 8.1
Direct X 11
LG E2442-TC (E2442TC) Monitor
CORSAIR CX series CX500 500W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply

Last night I came home, installed GPU-Z. Played my game while it ran. Highest temp reached was 57C. At 9:30pm installed Prime95 and ran all 4 workers using blended option. It ran for 14 hours with all tests passing and zero fails/crashes. This morning I ran Unigine and Prime95 with the Small FFT settings at the same time. I set the graphics quality to ultra. I started crashing like I normally do. I pulled an event viewer and pasted the results below. Is the error my bios for my motherboard? Is it my PSU?

The benchmarking ran on Unigine and it displayed that my GPU temp ranged between 60-62C and my Max FPS was 40ish.

Can anyone point me in the right direction?

Normally this is associated wit a hardware or driver problem, might make sure all drivers and BIOS is up to date, if available I'd try with another PSU (the CX series has weak caps and can fluctuate causing problems, can also check the DRAM with Memtest for starters.....if no joy get back to us, but have a feeling it may be the PSU

Thanks Trades!! My video card drivers are up to date. I've been hesitant to update my MB as I'm not sure how to do it correctly/safely. The manual is not very clear s I don't have much experience with Asus boards.

Also, I have a second PSU from my old rig (see below). Will that be able to handle my current rig setup?

Thermaltake Black Widow W0319RU 850W ATX 12V v2.3, EPS 12V v2.91 CrossFire Certified 80 PLUS BRONZE Certified Modular Active PFC Power Supply

Well I installed the other PSU on Thursday. Went two days with stress testing with Prime 95 and Unigine. No issues. Played games those past few days, no crash. Was thinking all was well, but then it just happened again. Any other suggestions?

I went into BIOS to check my memory to try and up the voltage an additional +0.06. Can you confirm the below is normal settings in the BIOS. I have not overclocked anything:

Voltage 1.535

DRAM Status:
DIMM_A1: N/A
DIMM_A2: G-Skill 8192MB 1600mhz
DIMM_B1: N/A
DIMM_B2: G-Skill 8192MB 1600mhz

CPU Input Voltage: 1.760V
DRAM Voltage: 1.535V (Is this the setting to boost +0.06V?)
PCH Core Voltage: 1.062V
PCH VLX Voltage: 1.500V
VTTDDR Voltage: 0.750V
DRAM Ctrl Ref Voltage: Auto
