I haven't tried this yet, but I will try if the error persists. Thank you for your help.
I've change the Tdrdelay from the default setting to 12. I haven't had any problems for days, but I'm not sure yet if it's a solution.
I have the exactly same issue here and Win DBG shows the same code: VIDEO_ENGINE_TIMEOUT_DETECTED (141). The error always points to the file nvlddmkm.sys.
I put my RTX 2060 in an old computer with an I7 3770k (works). I put a gtx 770 on my new buid and works too. I can't understand what is...
