Hello, so I've been spending the last month diagnosing my computer. It has been randomly freezing (not shutting down, not BSOD, but complete lock up without warning). The system will lock up both while underload or not. I do a lot of 3D and Video render and I have had it freeze during heavy load. But also I have walked away before with the system sitting on the desktop and came back to it frozen. Both seem to happen often with no real rhyme or reason. I've narrowed it down to either motherboard or GPU. I will get to how I came to this conclusion in just a sec, first here is my system.
Motherboard : ASUS M5A99X EVO R2.0
Processor : AMD FX-9590
RAM : Corsair Dominator DDR3 16GB (4x4)
GPU : 2X MSI brand Nvidia GTX 760 4GB (SLI)
Storage : Samsung 840EVO 250GB SSD (primary C drive)
Samsung 840EVO 500GB SSD
Corsair F60GB2 60GB SSD
WD Black 2TB
WD Blue 3TB
WD Black 640GB
Display : 3 Monitors using Nvidia Surround seen by the OS as a single 5670x1080 display
Power Supply: Corsair 860i Platinum, 860watt
OS : Windows 10 Pro
Now here are the steps I took while diagnosing my system.
1. Ran MemTest86+ off a flash drive for about 10 minutes before the system froze. This eliminated the hard drive as the system was running off my flash drive but pointed at the RAM as the problem, so I took the RAM out and put it into another system and ran the same MemTest86+ drive for 48 hours without any errors. So the RAM seems to be fine.
2. Ran Prime95 on my CPU for an hour without a freeze up. So CPU seems to be fine.
3. Ran FurMark and Valley GPU tests for 30 minutes without system freezing
4. I always keep Speedfan up on my screen so when the system freezes I can see what the temps where when it froze. They are always in the normal rage (~20C to ~50C).
5. That being said when my system freezes all the fans go to 100% speed, since I know it is not overheating it seems like the BIOS are no longer controlling the fan speed. This is one of the main reasons I think it is mobo.
6. I took one GPU out this morning and I am running Blender renders and it seems to be doing fine. However I have had it go for a day and a half without freezing, again no real rhyme or reason. I will keep you posted on this. I cannot put the GPUs in my other system because my power supply in that system does not have 2 8pin GPU power lines.
7. I don't think the system is under powered because it has been running fine since February 2014 without any problems until about a month ago. I do have my system plugged into a UPS and under load it only pulls about 700 watts, and that is including monitors, system, and external HDD.
Any suggestions on something else to try? Right now I am leaning to the problem being the mobo, but if anyone else has any ideas I'd love to hear them
Thanks!
