Solved BSOD, PC freezes then hangs after playing games, Bug code 116

[Haunter93]

Hi all, I've been getting BSOD quite often while playing games, mostly FPS with high settings. The most my PC could last without hanging/freezing is up to 6 days.

My mobo is 5 years old but it's stable when playing Diablo 3.

Using Blue Screen viewer, I get these culprits:
dxgkrnl.sys+5d134
dxgmms1.sys+37f3c
nvlddmkm.sys+9a57a0

Bug code: 116
Caused by driver: dxgkrnl.sys

I've googled and scoured these forums and tried various fixes
- uninstalled my nvidia drivers using driver fusion and reinstalled them again (latest is now 340.52)
- used the windows update to check for any directX updates (they reported everything is installed)
- Using the Nvidia control panel to change preference from Quality to Balanced (this does prevent the BSOD but for up to 3 - 6 days)
- I changed the battery for the motherboard using my friend's advice (this change can last about roughly a week)

The longest I've went through without BSOD is about a month before it starts to give way again.

My power source is 800v.

Attached is my dump files from DM log collector. Appreciate any help. Thanks a bunch and do let me know if I missed out anything. Still new in posting stuff in this forum.

Found the problem. I ran the Memtest and found that there was a broken 4gb ram in my slot. Removed that and things should be running smoothly from now on.
