Désolé pour toi
Fin 2018 correspond à la période du pic des problèmes de fabrication des puces RTX (contamination chez TSMC seulement avouée en janvier 2019)
Ce problème est sournois car le comportement est variable selon le degré de contamination.
Et dans ton malheur tout le monde se défausse de sa responsabilité
Vu le montant, je te conseille de porter plainte, c'est gratuit.
Et si tu comprends l'anglais et que ça t'intéresse, voici l'explication la plus probable car Nvidia ne le dira jamais :
"Facts:
- all models from all brands are affected: this problem can impact any RTX card
- different PCB with oversized power supply and cooling are also affected: so it's not a problem related to temperature or power failure
- cards can die with Micron memory (used from the beginning so widespread) but also with Samsung memory (used later): so the problem is not related to the memory, otherwise it would mean both Samsung and Micron are unable to manufacture GDDR6 (moreover without giving any explanation on other types of death with no artifacts)

- we can see different type of death with different symptoms: it's hard to believe that this RTX generation is cursed to the point of undergoing several types of problems
- the core itself remains the only common point between all these dying cards: knowing that some cards are still working fine, then it's not a faulty design of the Turing architecture from Nvidia
- The survival time is variable: this implies abnormal and progressive deterioration of the core over time (not detectable at factory)
- we learn at the same time that TSMC 12nm fab who builds RTX has suffered from a serious contamination: but little information provided to not scare away customers and investors

- a contamination of the core can appear in many ways: when the memory controller is affected (inside the core) then we can see some artifacts (corrupted cache), if the card has light contamination level then it can survive longer but with strange behavior (power drop, freezes, crashs, temperature spikes...) and if the core is seriously damaged then Windows shows blue screen with core dump and card not detected by device manager
If someone has a better explanation, I'm open-minded, but do not expect any information from Nvidia, who has flooded the market with their TOXIC RTX, leaving the burden to the customers to clean all their bad inventories until the last one!"
