Suddenly PC cannot handle high load

[kapos]

Hello there LTT forums family.

 

Yesterday i was normally playing Overwatch on my PC when all of the sudden it displayed a pink screen with weird patterns and froze. Since that moment i have not been able to do any high demanding task on it without the same thing happening and me having to force shutdown/restart. Although it has not been the same pink screen with patterns, i think the color and textures depend on what it was displaying at the moment of the halt / crash / freezing. 

 

My PC specs:

 

• MSI Z87-G45
• core i7 4770k with hyper 212 EVO
• ASUS R9 280x
• 8GB DDR3 Corsair Vengeance
• 500GB Samsung SSD
• Thermaltake Smart SP-750 80 Plus Bronze (750W PSU)
• Windows 10 64 bits.
• MSI Afterburner (Had it for quite a while now without any issue)
• AMD Adrenalin 20.4.2 (or W/E it's called)

 

Things i have already tried:

 

• Windows RAM test, no errors detected
• Uninstalled recent programs
• Roll back the graphics driver which was updated a few days ago (4+)
• Run different Software for testing such as a few found here: https://www.raymond.cc/blog/having-problems-with-video-card-stress-test-its-memory/
  • GpuMemTest gives no error
  • OCCT
    • Yesterday i tried separately CPU and GPU stress tests for a few minutes and nothing happened. Nevertheless when i tried the "power test" which stresses them both, the failure happened.
    • One time the system failed even at the menu of this program.
• When i try to play Overwatch system crashes a few minutes past start.
• Temperature at time of failures are same as usual (Case has a few fans aswell)
• Scan the PC for malware
• Changed virtual memory size

 

Any suggestions will be well received!

 

Pictures of 2 of the crashes are down below

does event viewer show anything?

@kapos How much do you tweak your GPU Fan Speed and Memory Clock on MSI Afterburner?

[Skiiwee29]

DDU your drivers and reinstall 100% clean and fresh. if that doesnt help it, your GPU is likely failing.

The only critical event is the "Kernel-power" event that says that i forced a shutdown,

No overclocking, i just use it to set a better temperature vs fan speed curve.

Ok! Will do in a few hours and will get back to you

I had a similar issue to you recently except my whole pc just shut down. I went through all the same troubleshooting and it came down to the PSU. I had the exact same PSU as well.

 

I ended up changing it out to a be quiet straight power 11 850w. Ran the same tests and had no crashes at all.

 

I highly suggest trying out some other solutions first though, especially if your a bit short on $$

sounds like your psu.

do you have another to test with? or might get lucky with blowing it out

I do have another one but it doesn't have the 8pin connector for the CPU nor enough power connectors for the GPU. I opened my PSU, tested some components and everything seemed alrighty. Only dusty. After a few more tests using OCC now the pc doesn't manage to boot with the graphics card in. It barely shows the Windows loading bar but then the screen goes black and my mouse and keyboard lights turn off (pc components remain running tho).

 

I had no way to discard the PSU as the issue but the screen showing red bars even at boot time makes the GPU the obvious guilty one here doesn't It?

Sure it can, but need something to test against either another p su or another GPU.

 

You could also try run your system with no GPU. Using the igpu from the onboard graphic but that's going to be less of a load.

Sorry i forgot to mention, pc works fine using  Intel integrated graphics.
