Hey guys,

My 2yr old Lenovo Y400 has been serving me well but since January it's been experiencing random crashes especially while gaming.

I'm a casual gamer and the games I played the most are usually Dota2 and GTA4. Before any of these crashes happen, I experience a stuttering/lag gameplay (even when minimized to desktop, sounds also stutter when this happens) for a few times, then the crashes start happening.

Initially it only crashes when I'm in the 2nd or 3rd game of Dota2, but it started to happen more frequently to the extend of only 30 seconds into the game. Currently I'm also experiencing random crashes while doing normal web browsing and surfing /k.

I have run a stress test on it and this is the result of the maximum temperature:
Intel i7 Quad-core: Reaches average maximum temperature of 85C
Nvidia GT 750M: Reaches maximum temperature of 95C

It achieves this temperature without crashing, I stopped the test to prevent frying the hardware lol.

This is the reading from HWMonitor prior to the crash:
Intel i7 Quad-core: Average temperature of 75C
Nvidia GT 750M: Average temperature of 68C

and it crashes without any warning? 

Now it's starting to crash while normal web browsing (rarely) with a reading of:
Intel i7 Quad-core: Average temperature of 58C
Nvidia GT 750M: Average temperature of 42C

The problem is these crashes occur randomly and there's no way to routinely recreate it. I've sent it to my retailer for checkup but he said he can't find the issue? 

Anyways I've called Lenovo Support regarding this issue and they asked me to send it to an Authorized Lenovo Service Centre and its a possible thermal/ motherboard issue. Just wondering if anyone else faced this issue before? It's so frustrating that it's driving me crazy Makes me wanna toss this so called "budget gaming laptop" out the window and get a macbook because #AppleMasterRace
