I'm curious, and just wanted to share in case you're not aware.
I see your system is overclocked (I do too).
I see a lot of settings still on "auto" and if i'm not mistaken you also have Turbo Boost enabled?
This may be where the issues start.
Are you using a utility to OC? Always OC from the Bios never a utility. If this OC was done using a utility it is most likely over volted and is definitely not optimized.
The SS above showing HWMonitor, are those temps on idle or under load?
The maximum CPU Core temp for stability reasons of an FX chip is 55c.
What I think I see is your CPU Socket temp (59c?) is already in need of active cooling. Very common for gigabyte mobos.
32GBs of Ram on FX /AM3+ is only supported up to 1333MHz iirc. Maybe higher depending on chip but only after stabilizing at 1333MHz.
All Dram specs should be manually entered into Bios, not left on "auto".
Using all four Dimm slots will require additional Dram Voltage and CPU/NB voltage to stabilize. 4 Dimms places a lot more load on the IMC inside the CPU.
The advertised Dram voltage is rated for Intel which uses less Dram voltage by nature.
It's very common on the AMD platform for an addition .05v to .1v Dram voltage to stabilize even for stock freq and timing.
If you add in the fact your CPU is OC'd to 4.0GHz this can also cause another need for additional Dram voltage.
Freezing is usually a sign of a lack of Dram voltage or CPU/NB voltage and sometimes a combination of the two.
If you've run this system this way (untested for stability) for a period of time you're probably dealing with corruption in the OS due to bad OC.
It can happen very quickly with a bad OC. Been there and done that.
There's always a chance of corrupting the Bios as well. I've also managed that one too so I do speak from experience.
Have you cleared the CMOS, undated Bios (if necessary), clear Bios again afterwards, and than re-tested using default settings?
I've seen many strange things change/happen while overclocking. Sometimes "auto" values are changed without you knowing it because it will always say "auto".
Only way to restore it may be to clear CMOS and Flash Bios. Than start over/try again with some possibly new knowledge.
If nothing else this may help rule out bad OC or corrupt Bios from the picture.
