I'm experiencing the weirdest BSOD in my entire time with Windows.

I don't have a screenshot of my error but this looks pretty much the same:

The strange thing is that this BSOD seems to be happening after the system has been idle for some time (20 minutes to a couple of hour), but it doesn't happen all the times; in fact, it happens very rarely (maybe one or two times a month). I'm unable to reproduce it or find any triggering cause or any pattern. Nothing.

Event Viewer is also not helping me at all, all i ever found there about this is the exact time the BSOD kicked in. Additionally, no memory dump is collected even though i have an active pagefile (which should be required to collect memory dumps).

Here some system info

- OS: Windows 7 Ultimate x64 SP1 (all Windows updates installed)
- MOBO: Asus z87 Deluxe
- CPU: Intel 4770k (OC @ 4.3 GHz 1.258 v, all C states activated, EIST activated)
- RAM: 16 GB g.skill TridentX @ 2133 MHz (XMP)
- VGA: Nvidia GTS 250 (with latest drivers)
- Main drive: Samsung 830 256GB

The CPU is watercooled and idle core temperatures (which is when this BSOD happens) are around 25-28 °C. The OC was also stable under Memtest for a couple of passes, prime95 for around a day and LinX for 15 passes.

I know i should test my system with base clocks first, but how am i supposed to conclude the problems is OC with an unreproducible BSOD?

PS: i was uncertain if to post this under Overclocking or Windows section; if this is not the right place feel free to move it.

Blue Screen View doesn't find anything because (as i said in my first post) no memory dumps are collected when this BSOD happens (neither regular dumps nor minidumps)
