Custom Built Rig

[MajorLeeSkrewd]

So I have a custom built PC, Specs Below:
Thermaltake Power Supply 850W
Gigabyte 990FXA-UD3 V4.0 Motherboard
Corsair H90 Liquid Cooler
AMD FX-8120 CPU
Corsair Vengeance Pro Series 1866MHz (4x8=32GB) DDR3 Memory
3 - OCZ SSD's (2x250GB & 1x500GB)
GeForce GTX980 GPU
Windows 10 64-bit
Just reformatted, All Drivers up to date. SSD firmware up to date, BIOS up to date (Graphic Card & Memory are brand new)

My problem is that my PC crashes randomly, Sometimes during boot up. Sometimes during game playing. I set the PhysX to run from the GPU instead of the CPU thinking my CPU could be the bottleneck. That seemed to stop the crashing for the time being (4 hours of The Division with out a crash). If the PhysX on the GPU was in fact the fix, I still have 2xGeforce GTX560 (Super clocked) sitting in my basement. Would I be able to hook these two up SLi in my rig and use them for PhysX?

Which Thermaltake psu do you have? Most Thermaltake psus are not very good, and could be the source of your problems.


Side note: Yes your cpu will bottleneck a GTX980 a LOT.

Have you ran Memtest on the new sticks? Try each stick individually?

 

[MajorLeeSkrewd]

My Power supply is a (Thermaltake Black Widow 850W ATX 12V), I have been using this same set-up for 3 years without an issue. Then about 6 months ago the crashes started happening (New Memory and GPU were just bought in May). I have run Memtest on the RAM sticks and they are all good. Sometimes when it crashes it doesn't reboot. The Mouse, Keyboard & monitor shutoff but the PC stays running. When this happens pushing the reset button doesn't even work. So I have to pull the plug or flip the switch on the back of the power supply to get it to reboot.

Overclocking at all? Since it stared before the new GPU and RAM, that basically eliminates them. Fresh install didn't help. It's odd that you lose video signal completely while things stay running. Any kind of errors in Event Viewer from this? Has your OS always been installed on the same SSD?

 

[MajorLeeSkrewd]

Yes, My OS has always been on the same drive. it is one of my 250gb SSD drives. I just recently updated the firmware prior to reformatting. I believe my BIOS does the active overclock for my PC. I have not made any changes to the BIOS besides flashing the bios prior to reformatting. My son just played CoD3 for 2 1/2 hours without an issue today. As soon as he closed out the game and exited steam the system rebooted. once the PC hit POST instead of rebooting it completely shutdown. My event viewer which only goes back to Tuesday (When I reformatted) Shows 10 critical errors (All are the same "Kernel-Power" Event ID 41)

This is sounding like a PSU issue to me given your newest information. Odd reboots for no reason and shutdowns are a common symptom of a failing PSU. Outside of this, what are your temps like? Possible your CPU cooler pump is malfunctioning causing overheating and shutdowns. These are the most likely culprits from your description at this point.

 

[CTurbo]

Yeah sorry that psu is garbage. That's definitely your problem.

 

[MajorLeeSkrewd]

on Idle my CPU temp is around 45c, After a couple hours of gaming it doesn't go above 85c.

P.S, Thank You for all of the comments. I really appreciate the time you guys are taking out of your day to respond to me.

Your CPU shouldn't be near that hot from gaming, especially if your running stock or lightly OC'd w/ a AIO kit. Speaking of which, if your BIOS is "active overclock", I'd try setting back at stock speeds for your CPU until this is solved.

 

[MajorLeeSkrewd]

My CPU has always seemed to run that hot, As I type this just with a browser open, my temp spiked to 74c then quickly cooled down to 29c. Could it now be a temperature issue and not my PSU? I just don't want to go out and drop 100+ on a PSU when I should have dropped 100+ on a New Heat sink or Liquid Cooler.

 

[1LiquidPC]

I'd check your CPU cooler first to be sure. Is the mounting good? Does What speed is the pump running at? Thermal compound might be dried out after the 3 years you had the system running so far. What are you using to get temp readings? It's very likely temps or PSU causing your problems.

 

[MajorLeeSkrewd]

I am using HWMonitor to check Temps. Going to try re-applying some New Thermal paste to see if that works. Been playing the division all morning with no crashes so far. Going on 12 hrs. without a crash. But I also haven't shutdown the PC in 12 hrs. letting it go into sleep mode. Fan for the liquid cooler runs 2657RPM (load) & 2170RPM (idle). Not sure how to check the Pump speed since it is an internal liquid cooler.
