SOLVED Even though tests didn't give me anything, by switching out some of my ram, discovered that one of the two sticks was causing the issue.

I built a system back in May using some older parts and some newer. Within my old machine, no problems whatsoever.

Build:

Motherboard: P8P67-M Rev 3.0 (new)
CPU: i-5 25 (new)
Memory: 2x4GB Gskill PC3-12800H DDR3 (new)
Graphics: ATI 5850 (old)
HD(s): 1 WD and 1 Seagate (old)
Case: Thermaltake Armor A30 (new)
PSU: OCZ600W (new)

So I am getting hard reboots. No minidump generated, no bsod but just like I hit the reset button. In my old build, I had none of these problems however, when I built my machine back in May, the problems immediately started happening.

In any game, within 20 minutes to 1.5 hours, the random reboot would occur. This isn't just in games though as it happens during random sessions but less frequently, maybe once a week but with gaming this behavior is consistent.

What I did so far:

-I changed the PSU from the OCZ600W to a Corsair700W PSU
-I ran memtest86+ for several hours with no errors
-Changed ram positioning
-Double checked connections
-Ran temp logging during gaming sessions

CPU (RealTemp):

Date : 9/16/11
Time: 14:34:00
C0(F): 131
C1(F): 136
C2(F): 131
C3(F): 133

GPU (GPU-Z):

Date: 2011-09-16 14:34:07
GPU Core Clock [MHz]: 725.0
GPU Memory Clock [MHz]: 1000.0
GPU Temperature [°C]: 78.0
Fan Speed (%) [%]: 33
Fan Speed (RPM) [RPM]: 2320
GPU Load [%]: 85
GPU Temp. #1 [°C]: 78.5
GPU Temp. #2 [°C]: 82.0
GPU Temp. #3 [°C]: 81.5
Memory Usage (Dedicated) [MB]: 362
Memory Usage (Dynamic) [MB]:93
VDDC [V]:1.088
VDDC Current [A]:34.8
VDDC Phase #1 Temperature [°C]: 67
VDDC Phase #2 Temperature [°C]: 67
VDDC Phase #3 Temperature [°C]: 66

If anyone has any decent clue this would be very helpful.

Edit: Nothing is overclocked.

What you are describing are typical heat/power symptoms. What, if anything, are you overclocking (CPU, GPU, memory)?

Power or Bad ram, Vram or onboard ram.

Would it be a good test to keep one of the two sticks of ram in there and then play the same games?
