Driver IRQL Less or not equal BSOD

I've been getting this BSOD for quite some time now (a few months easy) and I've been slowly sorting through drivers and software trying to find the cause. All I can tell is that it seems to happen most of the time while I'm playing games (though I believe it has happened overnight when I left the pc on with no games up). The BSOD gives me no other information than the title, so I had nothing to go off until I finally found a way to read the minidump files. After googling the files I tried a complete reinstall of windows to repair the files in question as they're Windows OS ones, however I again was frustrated with another BSOD of the same type. Here's the minidump from this one, I've lost the others due to the reinstall:

Please help as this is really getting frustrating to be getting these BSOD's constantly at the most annoying times.

The offending driver netio.sys appears to be a Windows system file. Have you tried running sfc /scannow to check/repair the system files? I've had the Driver IRQL Less or not equal BSOD error but this was due to a graphics driver problem.

You try an in place repair install if the obvious fixes don't work.

Yeah I'd noticed the windows file, that's when I stopped trying to fix drivers and work on that file instead. I've tried a scan and repair with windows, and when that failed I reinstalled windows completely and still got the error afterwards.
