I have received a new computer 3 weeks ago, and since then I have had an annoying issue. Here and there, the screen goes black (and the monitor doesn't spot any signal anymore) while the computer remains on. This forces me to turn it off and on manually everytime. After the reboot, the message:" default radeon wattman settings have been restored due to an unexpected system failure" appears.
I have searched and tried a few solutions to fix this but none of them have worked. I have updated my drivers, uninstalled by drivers to install new ones (with DDU as well), tried to change a few settings.
Here is my GPU infos : http://gpuz.techpowerup.com/19/06/21/nsu.png (the driver is not the good one here because I just used the AMD cleanup utility and Windows seemingly uninstalled the bad driver but I'll fix that)
My PC -
intel core i59400f 2.90 GHz
Ram - 16 GB
Windows 10 home
Motherboard - MS-7B98
GPU - AMD RX 480
Would you have pieces of advice?
