Random BSOD?

[subharmonic]

Hi peeps - wondering if anyone has heard anything like this.

I keep getting random BSOD issues - varying messages such as IRQL_NOT_EQUAL (or something like that) - also got NTFS_FILE_SYSTEM, and MEMORY_MANAGEMENT.

I thought it might have been to do with my old EMU soundcard, but after reading up on a few things, I decided to do a complete fresh install - so now it's only got windows 8.1 PRO installed.

I don't have any additional hardwear installed other than a SSD for system, and a few other hard drives (of varying ages and spec).

I've got 16gb of RipjawsX at 1600mhz installed, running at 1.5volts.
Motherboard is using AFAIK the defaults.

It's a z87x-OC, with a 4770k at stock speed.



I have a dread that it's the memory causing the issue - but. I ran memtest86 (I think that's what it's called) and it came up with no errors.
Also ran the windows memory test and I'm 99% sure it said no errors too (but I don't remember it finishing the test or what it said as I was called away ).

So - what should I be trying to do to fix this?

See, I think at first things were hunky dory.
I had 4gb of Corsair Value ram installed in 1 slot, and that was it.

I then tried to see if my EMU 1820m would install ok, using legacy drivers from Vista/Win 7.

The soundcard is really quite old, but still well regarded, so I figure I may as well try and use it.

However it is a 32bit card (I think), and my system is Win 8.1 Pro 64bit
Not sure if that has a bearing on anything - but that's the situation.

I'm not sure, for certain, when these BSOD started happening, because it was within a day that I installed the soundcard, and then fitted this RipjawsX ram - so I thought it might be either that's causing the issue - so, I've removed the soundcard, and reinstalled windows.

Only now it's still happening - very frequently - and it's happening with varying messages - I'm sure the above BSOD are only a few that have happened, but I wiped the old installation, and I guess the crash dumps went with it.

(I only just discovered BSODviewer this morning and got to use it for about 30 secs before I had to leave for work - and there were only a couple of dumps saved then.)

bit more system agent voltage or digi/analogue

not sure what its called on z97,but its for memory controller,esp with 16gb

Come again????

Wazza - can you explain a bit more what you meant?
I played around with the ram modules last night, and I think that maybe at the moment it's working out - but I want to test a bit more.
