PC Restarting while gaming.

[Ripjawed]

So I just bought the Sapphire Nitro+ RX480 8gb, having switched from a GTX 780. All of a sudden, my PC is running into the issue of restarting while gaming. It's completely indiscriminate as well, occuring in higher intensity games such as Arma 3, all the way down to an older less demanding game such as Portal. I used the DDU software offered by Guru3D to fully uninstall all my drivers, then reinstalled directly from AMD, and it is still occuring. Not sure what to do, but now I'm getting wary of AMD and am thinking of RMA'ing and going with a 1070 instead. My PSU is 3 years old, but again this issue didn't arise until I replaced the 780, and according to the WhoCrashed program, it is being caused by "atikmdag.sys (ATI Radeon Kernel Mode Driver, Advanced Micro Devices, Inc.)." Kind of at the end of my rope here.

PC Specs:
Motherboard: Asus Maximus VII Hero
Processor: Intel Core-i7 4790k
Graphics: Sapphire Nitro+ RX 480 8gb
PSU: Corsair HX850 Semi Modular 80+ Gold
RAM: Corsair Vengeance Pro 16GB (2 x 8GB) DDR3-2400 Memory

are you overclocking the gpu?

 

[Ripjawed]

I clicked the wrong button voting on that sorry. The GPU comes overclocked, I have not touched the settings for it, just left it at what Sapphire sent it at.

do you monitor cpu temps?

if not install msi afterburner

turn on cpu/gpu temp monitoring in the OSD


play a game for a bit, and post back with max temps



another thing you can try:



go into radeon settings > gaming > global settings > global overdrive



set gpu clock to 0 ( 0 = not overclocked )

and increase power limit to +20%

Is there a special way to post those up? I use Afterburner and it's OSD in game. While playing my card never goes above 72, however the usage is constantly at 100%. This is new to me, as my nVidia cards would always waver around 40-60% GPU usage while in game. Also I do not see a Global Overdrive setting in AMD settings

you want usage as high as possible, usually means you are getting the performance you paid for

however if you are doing nothing, and usage is still 100% then you have something going on, like miner software malware

what about your cpu temps?




take a picture, then upload it to a free image website like imgur and post the link here

Here are the min/max temps according to MSI: http://imgur.com/a/wQcqZ
These were taken whilst playing WoW after my PC rebooted itself.

temps look good

try this:

go into radeon settings > gaming > global settings > global overdrive



set gpu clock to 0 ( 0 = not overclocked )

and increase power limit to +20%



play a game and see if you still reboot

Ah geez, I keep clicking the wrong thing, sorry. It's late and I'm tired. When I go into Global Settings I do not see a Global Overdrive option.

there should be two "buttons" at the top when you go into global settings


"global graphics" and "global overdrive"

Yea I don't get the overdrive, instead I get "Global Graphics" and "Global WattMan"

These are my settings for WattMan: http://imgur.com/gggDr9Q
However, every time I set the power limit to 20% it auto resets it back to 0 after pressing apply

go into it and set frequency (%) to 0

this should also help

i'm sad they choose to not give this to us 290x users

 

[Ripjawed]

Well, I did a little more digging and enabled a few settings in my Bios and discovered that my PSU was failing. Replaced it and no more issues. Appreciate all your help my friend.

If it's updating, theres something in Windows 10 settings where you want automatic or manual updating. Not sure where it is exactly, but you can Google it.
