PC is locking up frequently and I can't figure out why...

This issue is one that has plagued my system for months now and I can't figure out what is causing it. When it happens there are no sound or graphical glitches and both of my monitors freeze and sound cuts off. I usually don't even notice right away unless I'm actively using my computer. The only remedy seems to be a hard reboot.

I've been trying to use temp monitors to see if anything is overheating but everything seems to be running within safe temps. I have to be missing something... It happens most frequently when I've got videos playing on one monitor and a game on the other but not exclusively. I mostly play WoW and LoL so they aren't particularly taxing games. I'll be forever grateful if one of you can help me fix this...

System Specs:
Mobo - Gigabyte 990FXA-UD3
CPU - AMD FX-9590
GPU - AMD Radeon R9 390
RAM - 16 GB can't remember brand
PSU - Corsair CX850M
HDD - super old WD caviar black 1 T storage drive
SSD - Crucial 1 T boot drive
I've got a Corsair H110 as the CPU cooler as well.
No after market overclocking anywhere in the system.


Ill post an Open Hardware Monitor log that I had running when it happened last.

EDIT:
Dropbox link for the log:

At the very, very least - a quality 750W unit IMO.

Best bet would be something 850W or greater (AMD recommend a 1000W, but that's a little overkill).

If you plan to OC either the CPU or GPU, you can add some substantial power additions there, so 1000W may not be out of the question.

The EVGA SuperNOVA G2 850W (gold, fully modular) can be had for $120 or $100 after rebate:

FSP Hydro G 850W (gold, fully modular) is $115 / $100 (+ shipping)

If you want to push to 1000W the Rosewill Capstone G1000 (gold, semi-modular) is $125...

The 9590 is a very power demanding chip, with only select motherboards capable of managing the power delivery adequately.

To quote SR-71 Blackbird in this thread (among others)
http://www.tomshardware.com/answers/id-2561755/amd-9590-good-cpu.html

Your choices for the 9000 series:


Asrock 970 Performance
ASRock 990FX Extreme9
ASRock 990FX Extreme6
Asus Crosshair V Formula-Z
Asus M5A99FX PRO R2.0
Asus Sabertooth 990FX R2.0
Gigabyte GA-990FXA-UD3 R4.0
Gigabyte GA-990FXA-UD5
Gigabyte GA-990FXA-UD7
MSI 990FXA-GD80V2

AMD.COM

Warning: This power draw of this CPU is almost twice that of the average CPU. Due to this, AMD recommends using at minimum a 1000W power supply. For cooling, AMD recommends using either either closed loop liquid cooling or full system liquid cooling.

If your temperatures look ok in HWMonitor - I assume they will with an H110, but that poses the question, have you overclocked?

Your motherboard should be sufficient, but only Rev. 4.0 is stated as adequate. There may be modifications for R4.0 that are not present on prior versions.

You also want a quality PSU - a good lesson overall, but very important when using such power-hungry components.- the CX line of PSUs are far from the best, so that's a possibility too.

If your temps look good, and drivers are up to date, it's very likely to be a hardware problem - that I'd be pretty confident (given the components) thinking it'll relate to power itself, or the power-delivery to the CPU.

Between a 9590 and an R9 390 you have the potential to draw ~500W at theoretical max. Add in your other components and peripherals, you have the potential to draw north of 600W, which is a pretty decent 'pull' from an 'ok' at best PSU.

The 2015 revision of the CX line improved quality somewhat, but not to the point that I would recommend using it alongside a 9590 & R9 390

I'm almost certain the board is rev 4. I'm pretty sure I checked all of that out when I rebuild about 2 years ago. How would I go about checking this again? Should it be printed on the board? CPU, RAM, and mobo were updated in late 2014 and GPU and PSU were updated in late 2015

Only other components are a DVD drive and like 6 case fans. Do you think those would add enough draw to make the system unstable?

EDIT: just checked and the board has rev 4 printed in the lower left corner.

I'll try to turn off turbo boost and see what happens.

I really not sure when the problem started. I used to have an i7 920 system, but the motherboard died and I couldn't find any new ones that didn't cost an arm and leg so I rebuild in late 2014 to my current system minus the GPU.

The CX850 PSU isn't the best anyway - I'm not saying you're pulling in excess of that and that's a potential cause of the instability.

I'm saying the CX line of PSUs is far from the best, and may be incapable of providing consistent, stable power to the components (thinking CPU specifically).

Have you overclocked at all? A 220W CPU is a difficult best to handle at the best of times, before adding OCing to the mix.

The CPU and GPU are not overclocked. Since turning off turbo mode in the bios I have not had a crash. That might help for now while I look into a newer PSU. Got any recomendations on wattage or brand?

All quality PSUs, Tier 1 or 2 (http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html) made by either Super Flower or FSP.

Any of those would be perfect additions, and reasonably priced.

Beyond those, you get into Platinum or Titanium efficiency &/or well beyond $150.

Thank you for all the help, fellows. Your ideas got me on the right track and I think that turning off turbo mode has remedied the issue for now. I'll look into a better quality PSU for the long term to finally put a nail in this problem.
