Been running smoothly since I got it around 2 months ago until last night when I tried to load Battlefield 1 which crashed the PC, nothing responded and I had to pull the plug. Then again today the same thing happened when trying to load Battlefield 5. Managed to get Battlefield 2042 loaded and into a game but had incredibly low FPS. Turned on MSI Afterburner and I was at 10% usage with 95 degrees!

It usually runs at around 50 degrees 100% usage. The card is a MSI Supreme Liquid.

Strangely I was playing Assetto Corsa earlier with no issues whatsoever. The only difference is Assetto Corsa was through a VR headset and all Battlefield games was through a HDTV.

Any ideas?
 
If the pump is still showing RPMs that would be a good sign. Nothing to rule out pump failure.

Could be an air bubble. Try shutting down a few times and cold starting it. May dislodge it and get the pump working again.

Remove the card and rotate it through a few different angles with a gentle shake, re-insert.

After that, warranty I would say.
 
Thanks for the reply.

I was thinking it was a software issue, as Assetto Corsa was working fine with no issues during around an hour of gameplay.
 
How do you have it mounted? The radiator/tubes should be above the GPU so that bubbles don't accumulate in the pump. Though the only bad scenario really would be having the GPU radiator mounted to the bottom of the chassis.
