Solved Computer shuts down without warning

Specs: Windows 7
My computer has been shutting down at random the last few weeks. I've gone through some of the threads I've found on google and haven't had any luck.

Here is what I have...

-Galaxy 57NKH3HS4GXK GeForce GTX 570
-AMD FX-8120 Zambezi 3.1GHz Socket AM3+ 125W
-x4 G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3
-850W Silent Pro

Here's what I have done...

My PSU has been through RMA. I ended up getting a brand new one. I know that it is still a possibility that the PSU is bad but I find that far more unlikely.

I have done a fresh install of Windows 7. I'm considering doing it again because I've had a handful of errors that continue to occur. Not really sure why but it could be cause to try it again.

I have done a complete cleaning with a vacuum and compressed air including the Processor headsink/fan and the GPU heatsink/fan. There are no dust bunnies in my case.

I have changed outlets that my computer is plugged into to rule out overloaded outlets. It is currently by itself on the wall outlet.

I've looked in the event viewer on the unexpected shutdown entry. There is no bug code and beyond that I'm outside of my expertise.

So, who's ready to tackle this one? :)

So far after a second clean install, no errors and no crashes (knock on wood). I guess it could have been a glitch or something.

At what point did you do the cleaning? You should never use a vacuum on electronics due to the static that builds up in the hose & can then discharge into the components.

Did you remove the heatsink to clean it? If you did, did you remove the old thermal material & apply a fresh dab of paste using the middle dot method? Have you checked the CPU temp to make sure it's not overheating? Do you have the auto-restart feature disabled? Have you tested the RAM with memtest86?

The vacuum was used on the metal heat sinks once removed. I did not add fresh thermal paste however. I have not installed a program to check CPU temp. Auto restart is enabled. I ran the intel burn test but not the memory test. The burn test caused power failure. I'm currently doing another fresh install of Windows and I'll do both of those (CPU temp and memtest) once its finished and come back with the results.

You should definitely use new thermal paste (having first cleaned the surfaces).

Always pop back and let us know the outcome - thanks
