Dear sirs,
In mid October I had had assembled a PC using the following parts:
Motherboard: MSI K9N2 SLI Platinum.
CPU:9950 AMD Phenom x4 Processor 2.6 Ghz
Graphic Cards: Two Nvidia GTX 280 Geeforce in SLI configuration.
RAM: 4x Kingston KHX6400D2/2G.
Power supply: Thermaltake Cablemanagment 1500W.
During the first month, the 1st motherboard was burned. It was replaced by the local dealer using the warranty. Two weeks later the 2nd motherboard burned too! A week before the 3rd motherboard was burned!!!
All three motherboards were burned during the use of Microsoft’s Flight Simulator X through Vista Ultimate operation system. Somebody could tell ”do not use FSX again”, but that is the reason that set up that machine!
It is like someone is pulling the power cord. There is also a smell of burning plastic for some seconds.
Can you make an estimation of what is possibly destroying the motherboards?
Thank you in advance.
George from Patras (Greece).

There are certain elements on the MOBO which need fixing with a certain paste. It’s heat-proof stuff.
I will get more info on Thursday (Not in workplace on Wednesday) and post it here.
Thermal paste between the CPU and the MB. a thin layer no thicker than a sheet of good A4 paper!
Burning out the motherboard I doubt is the lack of thermal paste IMHO, Case heat being the most likely culprit. I have no fewer than four fans supplying cool air from outside while another four exhaust hot air from the case.
It is all about airflow over components. Badly run cables will cause heat to linger if they are blocking airflow. The same as dust build up in an older machine.

My bet would be cooling as well.
1) place large fans in the back of the case, to extract air
2) do not place the computer inside a casing like a desk, a dresser, …
3) if under a desk, make sure it is far from the wall(50cm minimum) and that air can go up.
Oh, and if you tried overclocking, don’t.
That said, you can confirm the heat issue with tools that monitor your mainboard. Case inside temp over 40°C is not good, CPU temp over 80°C is bad as well

Insufficient cooling?
Agree.

A while ago my computer had to be rebuilt following the failure of the motherboard. One of the possible reasons was that it might have been caused by a power surge or spike or something. I had had the computer for years before the motherboard failed, so it wasn’t a new one.

I wouldn’t have a clue…when i strike a problem my Grandkids fix it for me straight away!!!

using too much hardware?? too much for the motherboard to handle??
