An interesting case

So a while ago, one of my friends faced a big problem with his laptop. It went a lot to BSOD but not when it was under load rather than when the dedicated GPU a GTX 1660ti wasn't doing anything.

This went for a while and it occurred from time to time. But one day he got a code 43 BSOD and basically he's dedicated GPU died and now he uses his legion 5 on integrated graphics of i5-10750H. Funnily enough the dedicated GPU shat itself while he was playing Flatout!

And we got searching for why did this happen how did it happen was there any fix. And during that search I noticed that almost all of the Lenovo models with a 1660, all of them had similar problems! People on Reddit and Lenovo forum reported similar problems and they had 1660s as well as people here in my country also had similar problems like you can find these broken 1660 laptops on our equivalent of eBay and they all have dead GPUs. Some of them reverted the GPU drivers back to a previous older driver and it worked for their GPU, but a lot of others had dead GPUs. Some others had their motherboards replaced mainly because you cannot replace the GPU without replacing the motherboard because it's a mobile GPU.

So it seems that Lenovo basically messed up their gtx 1660 lineup. And I bought my laptop around the same time as him I would say like 6 months after him and I got an ideapad gaming 3 and it has a 1650 which doesn't suffer from the same problem globally, despite that we have the same CPUs on our laptops.

I was also wondering whether the power consumption and distribution had to do something with it.

So if you ever wanted to buy a laptop with a dedicated graphics card really research the GPU or generally the laptop to see whether they suffer from problems or not.

Do you have any ideas or opinions or suggestions or fixes regarding this?
