I am frequently experiencing BSODs and NVIDIA Kernel Mode driver crashes when playing Dota 2 since October 2015. I have no idea why this happens and I have done factory settings restore but the problem still persists. I have tried keeping my drivers up-to-date but it still crashes when I am playing the game. I also did a roll-back on the drivers and it doesn't help too. Downloaded the recommended drivers for my Lenovo PC model and still it doesn't fix anything. I am suspecting that it may due to a hardware problem, maybe a damaged Graphics Card or RAM problem. Can anyone please help ? Following are the specs for my PC : Lenovo Thinkpad Model W541 Windows 10 Pro Processor : Intel(R) Core(TM) i7-4710MQ CPU @ 2.50 GHz System type : 64-bit Operating System, x64 based processor Display : -Intel(R) HD Graphics 4600 Render : -NVIDIA Quadro K1100M Please tell me if there's more information you needed to help. Please refer attached DxDiag analysis and .dmp files included in the .zip file. Thank You.
