In the last day I have had my PC crash with some graphic artifact like this https://i.sli.mg/xSQBab.jpg with some sound looping.


This , i noticed happens just as the GPU fans start to spin up.
I Tried my integrated graphics, and all went well, so i removed the card and stuck it into the 8x PCI e slot, same thing.


I downloaded Furmark and decided to monitor the GPU stats, it crashed the same way within 10-20 seconds, again noticing the crash followed the spin up of the cards fans.


I decided to look at the temps, and noticed the temps go from 39c idle to 60+ within 5 seconds and the crash happens around 71C.


SO It's surely temp based but what i don't understand it, I have had this card running at 80C gaming and it be fine, but it seems to me thermal protection is kicking in but at a lower temp i'm used to game at without issue in the past.


Does the rate of temp climb factor in too amongst the actual temp for thermal protection?



I noticed the heatsink is a bit dusty , some clumps on the edge, but i'm thinking maybe add new thermal paste.
What you think?
 
It looks like it could be memory based. If it was me I'd download MSI Afterburner and slam the fans to 100% max out the power limiter too make sure it's not being held back by power. If it still crashes try lowering the Memory and Core clocks by 100 mhz, if it still crashes I'd say it would probably be the PSU maybe? Just keep lowering those clocks until they are insanely low to see if the crashing stops.

You could also run memtest for 2 hours just to do a quick sweep of that, I've learn't to think something else is causing a component to fail :D
 
This is what I've been doing this afternoon.

I have been experimenting with under clocking to reduce temps with Afterburner, I have underclocked core voltage and core clock and manual fan at 100% , I have managed to keep the system stable in gaming as long as it's under 70C, this of course is at the cost of FPS but at least i can game somewhat without it crashing.
It's odd that when it gets to 70-71C it crashes , when GPU's can handle temps much more than that.
Also when settings in Afterburner are at stock/auto when i game the temps go from idle 37C to 60C in 2 seconds
