Computer crashing -- Motherboard overheating?

[OneDoesNotSimply]

My computer started crashing randomly around 3 weeks ago, sometimes it happens right when restarting, but usually it happens a little while after starting a game. I've searched around for reasons on why this is happening, i've cleaned my case, updated my drivers, ran a registry cleaner, and i've narrowed it down to my motherboard overheating. My motherboard hovers anywhere from 70-90 celsius when not running any games, while my cpu is 6-30 and my gpu 30-40. I'm not clear as to why the temp is so high, it honestly might be that my motherboard has just reached it's end days. My computer only specifically crashes when I run higher quality games like Payday2, Arma 2, and even League of Legends, it doesn't crash when I run games like The Wolf Among Us or The Walking Dead. My gpu is nVidia GeForce 560 Ti, and i'm thinking maybe it might be my gpu that's overheating? Looking for any possible solutions here before I have to get it fixed.

What is your PC specification? Without those we can't help because we can only guess anything from head to toe.

Look in BIOS and you should see the temps that are off or too high. Probably the chipset if the MB. There is a heat sink that you can remove and clean off the old thermal paste and install some more. This happened to me with an old X58 board. Chipset idled at 84C. Removed the heat sink and saw that the factory machine missed and most of the thermal paste was on the edge and down beside the chip. I put a thin layer all across the chipset and installed the heatsink, etc and temps went down to 38C idling.

CPU: AMD A6-3670
RAM: 4.00GB DDR3 @ 799MHz (9-9-9-28)
Motherboard: Gigabyte GA-A75M-UD2H
Graphics: (Integrated card) HP S1931 / (Using this) 1023MB NVIDIA GeForce GTX 560 Ti
Storage: 465GB Seagate ST500DM002-1BC142

As for the heatsink, I don't have one because I have liquid cooling, i'll check the bios tho to see if that gives any clue to what's wrong. It's not my cpu that's overheating, that idles at 6 - 15 celsius and goes up to 30-40 max when stressed, the confusing part is that CPUID shows 3 seperate motherboard temps, one being stable, one being low, and another rather high, and the high one is the one that sticks out. Speed fan shows the same thing, and the confusing part is how it's getting those temperatures? I mean obviously there must be sensors in my motherboard, but why is one part hot, one part cool, and one part a stable temp? CPUID and Speed fan screenies http://imgur.com/Hr4MlfI,ameGJ19

Bios told me that cpu is 27 celsius and my total comp temp is 35 celsius.

Instigated a crash while watching CPUID, I was running Payday 2 windowed with 800x600 resolution, it lasted longer than normal, but here's a screenshot of cpuid around a minute before my comp hit the bricks. http://imgur.com/A2ofV54 The temps at the top are the motherboard readings, so maybe when the middle one reaches 100 my comp forces a shutdown? Other than that the only thing I could think of is FANIN0 at the top going to fast for the voltage output? I seriously have no idea, i'm just brainstorming ideas.

Where do you get the 799MHz for the memory? Is the memory timings and speed set correctly in BIOS?

What is the model of the memory kit?

 

[OneDoesNotSimply]

I got the specs from speccy, and the speed and clock is default, I haven't overclocked my comp at all. As for the model of the memory I made my comp off Ibuypower 2 1/2 years ago and this is the memory I chose : 4 GB [2 GB X2] DDR3-1600 Memory Module - Corsair or Major Brand -- If that helps.

 

[spooky2th]

I was trying to see the memory model so I could look up what the timings are supposed to be. probably something like 9-9-9-24 if they are 1600Mhz.

can you download CPU-Z? It will tell you what the specs are plus what they are actually set at.

 

[OneDoesNotSimply]

In COU-Z is says 800 mhz, 1:8 for the FSBRAM ratio, and (CL)9-(tRCD)9-(tRP)9-(tRAS)28-(tRC)37 and thanks for helping man, i'm thinking it might be my psu tbh, I have a crappy 700 Watt XION XON-700p12n.

 

[spooky2th]

All the Corsair 2x2GB 1600MHz memory kits I looked up here have timings of 9-9-9-24 and 1.5volts except for one kit which has timings at 8-8-8-24 with a voltage requirement of 1.6volts. A 700 watt PSU should work very well with your system unless it is starting to choke/die on you.

 

[OneDoesNotSimply]

Yea a 700 watt psu should be fine, but it's a no name company and i've had it for 2 1/2 years so i'm starting to question it's integrity.
