BSOD Complete sporadic, not triggered by intensive use. ntoskrnl.exe

Hello, I am hoping I could please get help with my problem. I am having completely random BSOD, its sporadic and does not seem to be triggered by specific events. I have had periods of complete stability, and then Ill have periods where It crashed 3 or 4 times a day. I have not made any Hardware changes. Ive tried fresh install, 8 passes of memtest86 (no errors), chkdsk /r, and it has been no help.

I have tried using a viewing to diagnose, and get the following info:

Caused by Driver: ntoskrnl.exe (but i know this could mean anything)
Bug check codes:
0x1000007e
0x0000003b
0x0000007f
0x0000001e

I am uploading my latest mini dump files.

I hope someone can help me with this... Im about to buy a new system.

Best regards,
JWOO

Versatile BSODs with nothing precise, but there is always a hint of display failure.

Install the latest WHQL display driver only.

• Uninstall All nvidia items in Control Panel > Programs and features
  
  • 3D Vision Control Driver
  • 3D Vision Driver
  • Graphics Driver
  • HD Audio Driver
  • PhysX
  • nvidia Update
  • GeForce Exoerience
  
  (Are you using nvidia chipset drivers? If so, dont uninstall anything other than those are listed).
• Now follow Drivers - Clean Left over Files after Uninstalling
• Go to Drivers - Download NVIDIA Drivers, Download and install the latest WHQL. While installing, Select Custom (Advanced) install. In the next page, follow this settings:
  
  

That is, install the Display Driver and the PhysX only.

Also, such a versatile BSOD is a close indication of a failing hardware, sometimes. Take some hardware tests as well.

► Test your RAM modules for possible errors.

Run memtest86+ for at least 8 consecutive passes.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.
