Windows 7: Very Frequent BSOD on my new machine

Hi,

I recently bought a new pc and installed Windows 7 Ultimate 32-Bit OS. From the day 1, I ve been getting more frequent BSOD. all BSODs differ in their error message, so couldnt able to guess the faulty driver. not sure if its any drivers fault or issue with my RAM/HD/MB. attached are the reports & BSOD dumps. could you pls check and figure out the exact problem in my PC?

Intel I5 760
Intel DH55TC
4 GB DDR3 RAM

Seems to be caused by nvlddmkm.sys, part of the Nvidia display drivers

Causes:bad RAM, incorrect RAM timings/voltages, bad GPU, overheating

Uninstall the Nvidia drivers then use driver sweeper to remove the leftover Nvidia files
Guru3D - Driver Sweeper

Then reiunstall the Nvidia drivers:
NVIDIA DRIVERS 258.96 WHQL

Update DirectX: Download details: DirectX End-User Runtime Web Installer


This was likely caused by the following module: nvlddmkm.sys
Bugcheck code: 0x50 (0xC1CFFFF6, 0x1, 0x91AEA522, 0x2)
Error: PAGE_FAULT_IN_NONPAGED_AREA

file path: C:\Windows\system32\drivers\nvlddmkm.sys

This was likely caused by the following module: dxgmms1.sys
