X570-E Gaming - VGA-LED

[Lenz9300]

Hey I have a relatively new system.

The graphic card has been installed for a week.
I have been gaming every day for several hours with no problems.
CPU, GPU etc. always had very good temperatures.

Just now, after an hour, black screen.

It felt like it was shutting down for a moment.
When I wanted to start the PC again, nothing worked.

VGA LED is permanently white and I have a black screen.

What could I do?

ASUS ROG STRIX X570-E GAMING
AMD RYZEN 9 5950X
MSI Radeon RX 6800XT (Gaming X Trio 16G)

Have you tried this card on another PC, or remounting it (checking all power connections aren't loose)?

If problems persist, you will have to send the card in for service since it can be a GPU issue.

No, but after a CMOS clear I got back into the BIOS and did an update.
Now the PC starts.
But after 5 seconds of gaming the same problem occured again.
The PC hung up and I had to reboot.
But did not have to do a CMOS Clear.
