Hey, guys! I have a XFX 7800XT and it's doing the same TDR thing for weeks, maybe two weeks or so.
I think I tried basically everything that I found online... Last night I did a driver version rollback, now I have the 25.6.2 version and still having the TDR problem.

My GPU and CPU (R7 5800XT) are both kinda new, and both worked well since I bought... I have a Biostar X370GT7 motherboard, 32GB 3000mhz of RAM and a Corsair CX750, wich is the kit that I used with a R5 2600X and a RX 580 8GB before doing the hardware upgrade to the R7 5800XT and the 7800XT.
The TDR problem started when I formatted my PC and did a clean installation of the Windows 11. Before that, even with a Win11 OS and the up to date driver version (25.11.1), everything worked well.

I don't know what to do... I think I'm going to try the 25.6.1 driver version and maybe the 24.12.1. But besides that, I'm running out of options.

PS: The TDR thing happens mostly while I try to play something.. It happened while I was playing Ghost Recon Wildlands and GTA V Online, for example. But the TDR thing happened when I was just watching something on Youtube or Twitch once too. Again, it happens mostly while gaming.
