Hello once again toms hardware, i would like to request another help from your community.
I've been experiencing random reboots when i am playing low to high end games. This is my specs:

1TB WD
AMD FX8350
NVIDIA GTX 650ti boost OC edition
Corsair VS 550w
CM Seidon 120m
G.Skill 8GB RAM 1 Module
Gigabyte 970a-DS3P motherboard
2 Blue LED DeepCool Fans
2 Stock CM 120mm fan

The problem existed when there was a time when my computer was restarting without BSOD's or some sort of error. I've stressed test my processor and got it to be replaced with a brand new one. After the replacement, for a few days, there were no random reboots, and right after maybe day 4 or 5, those random reboots came back. I've done some test which i am not good at how to use it, mainly basic instructions and basic procedures from what i've read is what i've done. so far the results of my VC , PROC, PSU,HDD ,RAM, are okay or "passed". I've used hiren's boot cd application to test my hardware for errors and none seems to come out. My mind tells me that maybe the PSU, VC, or MOBO be the problems. Please guys, need really some help here. It's been 2 months now since i wasn't able to fully utilize my computer.

Running single channel memory mode stands out in an otherwise nice system.
Are you OCing the CPU or MEM?

Heat is the first thing that would cause a no warning reboot so what is the room temp. I see you have plenty of cooling but still memory or voltage regulator chips can heat up fast so air flow inside the case is important.

You could try running with the side panel off to see what happens, maybe try a fan blowing into the open case.

Voltage sags in the AC line can also cause reboots are you protecting your system with a UPS?

umm sir, good day, i've set my side panel to open for cooling, my temps for my proc is 28 degrees celcius, my video card is at 39 degrees, i've been wondering, my lights are flickering and the other bulb went off, does this mean i have a problem with my electricity? i don't have a UPS because i can't afford one. I don't like to OC sir and i have no idea on how to do it, i also can't afford to OC my proc or vid. sorry for my bad explanation sir.

First I am positive your temps are not while playing games.

Lights flickering is a good indication of voltage fluctuation.
Loose connections can be the cause, as can an imbalanced line load, usually caused by something like an air conditioner, refrigerator, heater or other high current load, on another leg or circuit as your PC.

Sometimes the main fuse box can be unbalanced with too much load on one side of the box detected with an amprobe checking the current draw on each leg and the neutral. When you have more current load on one leg the voltage drops on the other leg causing flickering and problems with electronics.

'At Home' does not give a good indication of where you live, like what country, so I have no idea what season or the specifics of your electric service.

Powering your PC using another circuit is one way to solve this problem.

A UPS is not that expensive these days and can be a big help if the power has occasional problems, but if too frequent it will drain the battery.

A DVM (digital voltage meter) can be had for less than $10 and just setting it for AC voltage and inserting it's probes in an outlet for several minutes at a time can show you what's going on.

If the voltage stays steady or just changes a couple of volts (of course measured many times day and night) then it is OK.

If the voltage jumps lets say for example from 119 to 90 or 119 to 100 continuously or very often, then you have a load imbalance.

thank you for the reply sir rwinches, i live in the philippines, and the weather here is warm, my temp are good my proce is ranging from 20 degress to 32 degrees, my video card ranges from 36 to 45 degrees.i will try your suggestion by buying a ups for my pc and using a DVM to determine if there is any fluctuation in the electricity. so far i've noticed in my computer by using event viewer that there is this error called kernel power failure. What does this mean? any ideas?.

Hello Everyone and i would like to update for the people who replied to me and who are willing to help me solve my problem, i went to the store where i bought my Computer, We were able to determine that the PSU is not the reason of random restarts of my computer because they've used another psu same brand with higher watts, it's a corsair VS 650, and for the HDD, they've used an app called HD Tune pro to determine if there are any bad sectors on my HD and so far all were green. My processor has been newly replaced but still they used some stress tests to be sure. Before i gave my computer back to the store there were BSOD's after a couple of reboots, i suspect that the motherboard is failing or the video card. Is there any similar problems like these occured to anyone aside from me?
