random BSOD that happens occasionally / not reproducible

k0ala2k · 25 Jan 2015

hey all,

I've got serveral different BSOD's on my system. A BSOD does not appear if I start a certain game. Most of the times the BSOD appears after the system is online for several hours. Sometimes while playing, sometimes while downloading content like playing a youtube-playlist (without me even interacting on the keyboard).

Until now I've ran MemTest (and it says Mem is OK), I've replaced the GFX Card and replaced the Motherboard. I also reinstalled the system.

Just can't figure out what the problem is

Let me know if you need additional information

Probably caused by : hardware ( nt!NtAllocateVirtualMemory+d91 )

Followup: MachineOwner
---------

Run a minimum of 8 consecutive passes, preferably overnight, or until errors occur using MemTest86+.

Reference:
RAM - Test with Memtest86+

Provide a photo showing pass or fail of the results when more than 8 passes have been completed.

took really some time... but here is the photo..
no errors and 9 pass, hope this is enough... running for 32G takes really alot of time

Does anyone have an idea what the problem could be? RAM looks like its not one of the problems after running memTest, right?

RAM looks OK. Proceed to the remainder of these tests:

If overclocking, reset all overclocks back to their default settings and then follow these:

CPU - run the HIGH test
CPU - Stress Test Using IntelBurnTest

Video - run the FURMARK test for 20mins
Video Card - Stress Test with Furmark

Storage - run the SHORT test using the DOS version
SeaTools for DOS and Windows - How to Use

The FurMark-Benchmark ran successfull.
The HDD Test of Seageate ran successfull.

But I had to abort the Intel Burn Test. As I've seen the temprature of 74° I stopped the test.
Also the test was only "standard" not "high".

I guess we've found the problem then? Would this be a problem of the CPU or rather the cooling?

Cooling. What type of cooler are you using?

k0ala2k · 31 Jan 2015

I'm using a "Scythe Mugen 4 PCGH-Edition". To me it's a real big cooler... I attached a picture of building the PC with this cooler.

Added some BIOS information. I could set the fan to a certain value using "manual"-mode.. but I guess thats not what I need?

I think it may be worth redoing the thermal paste, then reseating the cooler and fans.
