Always get blue screen while playing but don't know what?

I always get a blue screen on my gaming laptop when I play a more demanding game. (e.g. Gta online, Warzone) I don't know why, I have a GTX 1050 Ti with the latest driver in it and the RAM is maxed out at 50% during gaming and the CPU is 70-85%. I don't know why that could be. In addition, it is not a normal blue screen, but the blue screen comes for 2 seconds and then I only have a black screen and I don't know what the error message was.

Can you help me?

The error message would be relevant. Because of this, one can conclude what is causing problems. The most likely thing in my opinion is a memory error in the RAM

And how could you fix such a mistake?

You can only replace the RAM.

After the RAM is only 50% full, one way to diagnose it would be to remove a RAM latch. If the error disappears, you have found the faulty bolt, otherwise insert the one again and remove the other one. If the error persists anyway, the problem is probably something else, because both latches are defective at the same time is very unlikely
