XPS 15 L502X Crash

The GT 540M GPU crashes on every game, you name it. Only when connected to AC adapter and playing games. The only way to recover from the crash is to force shutting down the Laptop by holding down the power button. And tell me to try any more settings. I have tried every possible option in the world and there is nothing going to happen until Dell is going to address this issue.

I have nothing else to add and I'm fed up of this Dell. Now never in my life I'll go or recommend a dell to anyone. Instead I'll do a campaign to spread the word not to buy Dell Laptops.

The Crashing issue of GT 540M is living more than three years and Dell or Nvidia have not taken a small concern to fix this problem. I just feel like killing them all when they start over again telling me to do all the diagnostics from scratch.
