PC Crashes under stress. No Bluescreen

FrancisBar · Dec 25, 2015

After Installing the new AMD Drivers I have had various problems with my PC. The biggest one is when playing a game it crashes and resets the PC whitout a bluescreen. I think this might be from my 280X and I have tried rolling back the drivers, giving 20% more PSU Power in MSI Afterburner and even upgrading to windows 10 from Windows 8.1. None of these worked. I only rolled back the drivers on the 280X. There's also random usage spikes on the 280X as I can see on MSI Afterburner, there usage spikes occur out of nowhere. I would appreciate any help.

Here's my specs by the way :
MSI AMD Radeon R9 280X 3GB
AMD-FX 8350
MSI 970 GAMING
120 GB KINGSTON SSD
2TB Hard Drive
Hyper 212 EVO CPU Fan
Uranus Vx Power Supply 750w Silent Nox

Here's the Usage Spikes I'm talking about by the way : http://imgur.com/rcWbhFj

Bump Again. Sorry.

too much power to the GPU can cause a brown out to the CPU, the CPU then resets. If you have a good motherboard and PSU you will just get a black screen. With a low quality PSU it will often just restart and may get a bugcheck 0x124 on the next boot. (depends on the machine)

But the GPU got the same problems with the same amount or the 20% I have now given it. It didn't had these problems before. And can you explain the random power usage spikes?
By the way, it just crashes into a black screen, and doesn't give me an error code.

I would suspect it is not crashing in the operating system, the CPU is getting a reset signal from the motherboard and the motherboard is not letting the CPU start up again. That causes a black screen, the same as you should get before control is given to the CPU and BIOS. IE when you see the black screen there is really no OS running.

if you think windows is running, then you can google how to force a memory dump via the keyboard, make the settings and force a memory dump even if the screen is black. Then reboot and copy the memoy dump to a server to see where the system was hung. (might have to set some debug flags to be useful though)

Unfornately I can't force a memory dump. I have tried the instructions on google but it doesn't seem to work.
So yeah. I don't know if Windows is running or not when it crashes. I have also cleaned the connection of the GPU to the motherboard, didn't fix it also.

force a memory dump on the working system and put the dump on a server and post a link.
I can take a quick look to see if I see anything of interest that might help.
