Does the video card go into protection?

Question

Iron

Good to everyone! Please help, I've been struggling with a problem for two months, the idea generator is already refusing to work. there is no logic in what is happening.
We have 3 PCs:
PC1. Ryzen 5 2600 + Gigabyte gtx 1660 super (home)
PC2. i5 10400 + Radeon 6600XT (home)
PC3. Ryzen 3 3200g + 1050Ti (office)
Almost two months ago Gigabyte gtx 1660 super started to go into defense in games. The screen goes blank, the turntables on the video card are unscrewed by 100%, while the Windows work on Diskorod hears and speaks. Nothing related to the video card is registered in the Windows log. I drove it in a donut, in Aida, I watched the temperature, voltage, everything is normal. At full load in a donut, it can work for half an hour, it does not go into defense. 15 minutes in WoT drops 100%. I gave it under warranty, after a couple of weeks they returned it with a piece of paper "No fault found". For a while I installed 1050Ti from PC3 in PC1, it works without problems. In PC3, I installed a Gigabyte gtx 1660 super in the same tanks, it works, even to get rid of the underload, I made a virtual 2K resolution, and even so, two hours of play and nothing. Returned to PC1 dies for 15 minutes. I put the same problem in PC2, it stalls instantly.

Change everything in order. I would sin on power supplies. Second in line - mat. fees.
