Bluescreen (driver IRQL not less or equal) while playing games

Hello

I recently started having bluescreens that read "Driver IRQL not less or equal". It all started after installing dead island on Steam. First I got the bluescreen when normally exiting the game. Then it happened while playing it. After that I removed the game and did system restore to point before installing the game (note. The game also installed it's prequisities, like direct x 9 update. I can't remember what the others were).
Now I'm having the same bluescreen while playing Planetside 2. So far I haven't had crashes while not playing something. (I was able to play Rust for some time without problems).

I know reinstalling my pc would be the easiest fix, but I don't want to do that until it's the last resort.

I would attach the memory dump windows generated upon crashing, but it's 800 MB. Even the zipped version is 150 MB.

Edit. I found a program called bluescreenviewer. I was able to view the latest crash information and it had two entrys with red hue. I copied their information to BluescreenViewResult.txt

Sounds like you need to change your settings to make windows create a small memory dump when BSOD
Dump Files - Configure Windows to Create on BSOD

Had a quick look at your files and there is only one dump file dated today all the rest are over 12 months old spreading back to 2011 so we don't have much to go on here.

The recent dump file indicates an 0xD1 problem which nearly always relates to a problematic driver which is named as NEOFLTR which relates to Juniper Networks software, any idea what this is ??
If its something you don't use or need then try uninstalling all Juniper software

There seems to be a lot of software on your machine that you wouldn't find on a typical home users computer, is this an ex corporate machine or is it all things you have installed ?
