KMODE_EXCEPTION_NOT_HANDLED Windows 8.1 BlueScreen

it kind of looks like a driver bug (where a data structure is freed rather than returned to be reused)
SO:
overall, confirm memtest86 works
update or remove indicated drivers(below)
if you still get the bugcheck you will need to turn on verifier.exe and set some flags to have it check your 3rd party device drivers and bugcheck when it detects a bug. (it will be painful on a slow system and it will most likely point to your old device driver that you can not get a update to anyway)


- will take a quick look at the other bugchecks in a minute
( 2 bugcheck looked like the same problem, looks like a driver bug)

-because your machine is very old, you need to run memtest86 and confirm your memory system is running ok.

check for file corruption issues:
you will also want to run cmd.exe as a admin
then run
dism.exe /online /cleanup-image /restorehealth
this will check for corruption and restore corrupted files from a trusted online version
================
with this first bugcheck I think I have seen it before but when a screen saver was trying to use the memory card to build a new screen image before it was to be displayed. You have a really old card and windows might just be stupid enough not to know you don't have enough video memory to use a its own buffer. you might disable your screen saver if you have one (it would bugcheck when the next image is about to be displayed)


=============

you should also totally uninstall your graphics driver and sound support for the graphics driver and reinstall it.
it kind of looks like you have the graphics drivers from one build but the sound support driver from another build.
You will have to go into windows control panel and disable the automatic install of drivers, uninstall the drivers for the graphics card, then install a updated package reboot and go back into control panel and enable the automatic install of drivers again. (if you don't the plug and play will reinstall the drivers a few seconds after you uninstall them)

Both of those drivers are key windows drivers, they will not be the cause of your problem.
