However, blue screens continued even when I was just browsing the web or doing word processing. It gave me IRQL_NOT_LESS_OR_EQUAL, SYSTEM_SERVICE_EXCEPTION, and PAGE_FAULT_IN_NONPAGED_AREA codes.
On Saturday I changed the thermal paste on my CPU and the temperatures dropped instantly, however my PC continued to crash when I turned it on again on Sunday. Today I got more BSODs with SYSTEM_SERVICE_EXCEPTION, some without error codes, and one referencing Ntfs.sys.
I have performed video memory stress tests yesterday and a disk check and ram test not too long ago finding no errors.

I'm attaching the most recent mini dump files to this post.
Well you have at least 5 different cuases for these crashes. The most obvious problem you have is memory exceptions caused by either a driver
or your memory.
1-run memtest for 7-8 passes as indicated.
Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program.
Boot from the CD, and leave it running for at least 5 or 6 passes.
Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.
Test the sticks individually, and if you find a good one, test it in all slots.
2-Remove sptd.sys. Used by alcohol120 and daemon tools it is a huge cause of BSOD's.
Please remove any CD virtualization programs such as Daemon Tools and Alcohol 120%.
They use a driver, found in your dmp,sptd.sys, that is notorious for causing BSODs.
Use this SPTD uninstaller DuplexSecure - Downloads
when you're done you can use this Freeware MagicISO Virtual CD/DVD-ROM(MagicDisc) in its place.
3- Run a system file check to verify and repair your OS files
Run a system file check to verify and repair your system files.
To do this type cmd in search, then right click to run as administrator, then

Let us know the results from the report at the end.
