Palit GeForce GTX 750ti Random PC Freeze

[merchipang]

Good day to all of you guys here. I was hoping you could help me fix my problem.

I built my first PC last week, all of which are brand new. The drivers are all installed and up-to-date. The motherboard drivers and BIOS are also up-to-date.

Whenever I play games like Dota 2, Fallout 4, Tomb Raider, all of them crash randomly. I really don't have any idea what's causing the problem. I've read a lot of threads here in Tom's hardware and Nvidia forums and nothing seems to be of help.

CPU: Intel i3-6100 3.7GHz
Motherboard: MSI B150M PRO-VDH
GPU: Palit GeForce GTX 750ti DualStormX 2GB DDR5
RAM: 2x8GB Corsair Vengeance 2400 MHz DDR4 downclocked to 2133 MHz bcoz of the MOBO.
HDD: 1Tb WD Blue
PSU: Seasonic M12 Bronze II Evo Edition

I have tried updating the GPU driver to its latest version, still nothing.
I have tried the driver version of the CD included in the GPU, still nothing.

I've tried FurMark, PerformanceTest, and HeavyLoad to maximize the GPU performance and it seems that its 100 percent performance only gave me a 61C temp, the pc usually freezes at only 50C help guys, thanks a lot

I tried removing my other 8gb RAM cause someone I knew suggested it. Seems to work, hope it continues to work fine. Thanks in advance to those who will help anyways
