Question Lenovo S540 freeze / crash / BSOD when running games - whats wrong?

Jun 25, 2020
Hello guys,

So i have a Lenovo S540-14IML with the following configuration:
CPU: Intel Core i7-10510U
GPU: Intel UHD Graphics (Comet Lake-U GT2) [V0] [Lenovo] + Dedicated GPU: NVIDIA GeForce MX250 [Lenovo]
RAM: 8GB DDR4 @ 2666 Mhz
Storage: 512 SSD

Problem is, everytime i try to run a game that uses my dedicated GPU my laptop starts going wild. It will freeze, stutter, crash or just BSOD.

I have tried reinstalling Windows 10 several times, reinstalling drivers several times (using DDU in Safe Mode), nothing seems to work.

I'm not running too demanding games, League, Valorant, Counter-Strike 1.6.

I have tried disabling the dedicated GPU in Bios options, and everything works fine with integrated graphics, thou i have a lower FPS because of the weaker GPU.

I tried sending the laptop into service because the GPU might be defective (still under warranty), they responded that the hardware is fine, it's a software issue and they do not cover that.

Please help me out, i don't know what else to try.

NOTE: Tried running benchmarks / stress tests, everything is fine. Don't know how it only affects games..
