IRQL_NOT_LESS_OR_EQUAL Windows 7 x64

Happening at random. Everything is up to date, drivers, windows updates etc. This is a brand new machine that I've had for about 2 months. I have previously had a virus (SystemWin.exe/PsP2Clnt.exe) but have cleaned them to the best of my ability; I do think that I might require a clean install but I REALLY don't want to do that so this is kind of my last resort. I've ran the windows memory test and it says its fine, I plan to run MemTest86 overnight. I've attached all dump files over the last month and my sys info, thanks for reading.

Edit: Did some more research, there's one thing I haven't updated, my BIOS. B150M-A | Motherboards | ASUS Global It looks like I don't need it because it's for CPU support and mines been validated a long while ago as you can see here: ASUSTeK Computer Inc. -CPU Support- (i5 6600). I've never flashed BIOS and it seems I should only do it when necessary, wondering if I should ignore it?

Hello Chase mate do the memtest first but remember to run it for at least 8 passes any less and you may as well not bother. However if the errors come up fairly quickly then you can stop it.
Then it is a matter of testing each stick (am assuming you have two sticks of RAM) to find the rogue one and just replace it remembering again to replace it with a stick of close specs and preferably the same brand.

This is the test we recommend - if you didn't know already RAM - Test with Memtest86+ as the Windows feature I do not consider much good at all and 8GB may take some time a job best left for when you are not using the machine - overnight is a good time to consider.

The BIOS I would leave for now and you could run these too if you have been infected.

Just ran the test then for two hours and it only did 4/4 passes, how can I change the pass amount? I'll change it and run it overnight tonight. The BSOD as well as "Modification of a critical data structure or system detected" seem to only effect my system when I change the power setting to high power, so I have a feeling it's to do with voltage somewhere but I have NO idea how to configure that type of thing.

E: Ok I ran memtest86 overnight, it seems it did only 4 passes and I can't find out where to change the amount, this is what it looks like upon completion: https://i.imgur.com/cjdi6SG.png. The other reason I think it's to do with power, is that whenever I turn my PC on, I hear a pop or two thru my headphones, it sounds like a remnant of an electrical surge.

well mate if the memtest I linked only runs for 4 passes then something is quite wrong because it runs in a non Windows environment and the number of passes as far as I ma aware cannot be set I have seen some that overnight have gone for 15 or more.

Me I would be trying some different memory if you have some spare sticks.

In the BIOS I would leave set to default I don't think mucking around with the timings is going to do anything because if it is not working properly then why should changing the timings make any difference.

By the way if I haven't asked before are the sticks the same brand and the same timings ??

No Chase mate you have to use the memtest I linked RAM - Test with Memtest86+ the version is 5.01 I think now. The other I (and other members )would not even consider.

The timings mate should be printed on the side of the sticks see pic if there are no timings printed on the sticks you have try PART B: of this and other pic see pic
Using HW Info
PART A:
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT as a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE (sometimes the usual one for Gigabyte boards)
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
Limits +/-
12v = 11.4 – 12.6v
5v = 4.74 – 5.25v
3.3v = 3.135 – 3.465v
The Power good signal voltage at pin 8 on the 24 pin plug (grey cable) should be the same as the 5v rail reading/s
See this for the rail voltage info
PSUs 101: A Detailed Look Into Power Supplies (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
PART B:
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.

OK Chase mate of course the choice is yours and if those timings are for the sticks you have then there should be no mismatch.
If you are upping the ante for gaming then well 16GB would be plenty but even 8GB should be enough except for extreme gaming.
If you want and have the time I would run the memtest or you can go ahead and get the extra RAM - a tip though and that is buy the sticks in a same brand matched set - that is because they will have have come off the same production batch and more likely to be evenly matched.

I see from your specs your board is a four slot one and that means four channels (please say if I am preaching to the converted). Plus it says that you can use DDR4 memory too and if that is what you have in (from those timings it looks like it) then I would definitely go a memtest because it would not be that old.

If I were going to replace the RAM I would personally get a 4x4GB set because then you are utilising all the RAM channels (slots). You can go 2 x 8GB but then you will only be using two channels. But again please say if you are aware of this already.

If you want more info on what would suit your board ythe best then visit this site Welcome to the G.SKILL TECH FORUM join up and then post a thread and Tradesman will guide you he is really great when it comes to memory for dedicated boards / systems. Personally I like G-Skill RAM anyway.

Now the Asus support site for your board should have a recommended memory listing but I cannot find it or I would link it.

Just out of interest just what is the sticks brand and model?? - it should tell you that in HW Info.
