You have two different BSODs here:
UNEXPECTED_KERNEL_MODE_TRAP
STOP: 0x1000007f
Also:
STOP: 0x00000116
Referenced Drivers: dxgkrnl.sys
ntkrnlpa.exe
nvlddmkm.sys
This BSOD is often caused by drivers, overheating, faulty hardware etc. The most important thing to do is to update all of your drivers. Here is a list of thing to try:
Update all of the drivers you can.
Run Memtest86+ or another memory testing tool that came with your computer.
Make sure all windows updates and service packs are installed.
See if these BSODs occur in Safe Mode and report back.
See if there are any errors showing in Device Manager.
This problem may be caused by overheating, so can you please download GPU-Z and SpeedFan and write down/screenshot the temperatures of your cores/graphics card/hard disk. GPU-Z SpeedFan
The referenced drivers may point to your graphics card drivers, and so one of the first things to try would be updated graphics card drivers.
You also have some very outdated drivers (2002, 2005, 2006, 2007, lost time stamp)
These should also be investigated and updated.
