Constant system crashes(Deadlocks i suppose)

[SunChase]

Hello everyone. I dont really know if this is the right place to ask for help in such sittuations, but trying wont hurn(i hope).

The problem: when i'm playing a resourceful game(in my ocasion it's XLGames's ArcheAge... happens only there), my pc randomly freezes(the image and the sound, looping the last sound it played), and only Reset helps.

Usually this thing happens randomly and not very often(i'd even go for a once a month). But in the last few days i'w caught this 5 times already and it drives me crazy. The main thing is that i cant really track the source of the problem, cant really recreate it by choice.

But here is something i'w struck on:
1. I open the browser Chrome\FF\Maxthon(has up to 10 tabs).
2. I launch AIMP.
3. I start the game. And at some point the sound can begin to "buffer up"(maybe a software issue), sometimes continuing to play normally, and some times the system dies.

Today the client stood still for 30mins or so, and when i returned and resumed the music playback in a minute or two the system died.

Here are my system specs:
MB: MSI H97 Gaming 3(1.B bios, latest as i know). Before i'w had Gigabyte Z97 Gaming 3. The problem started there(that was my first Intel build).
CPU: Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz (4 CPUs), ~3.3GHz
RAM: Corsair Vengeance Pro CMY8GX3M2A1600C9 4GB x2.
GPU: MSI GeForce 960 4GB. Before that i'w had Asus GeForce 660, and it literally thrown this problem constantly(but when i game the board to my friend for a 'few weeks testout' he didnt have any problems with is). But in my case the only thing that worked was to downgrade the video drivers to 340(as i remember).
HDD: Storage Drive - ST1000DM003-9YN162, SSD - KINGSTON SH103S3120G (system, game client and windowses page file)
Power: Chieftec CTG-550C
Sound: Asus Xonar. The problem started long ago before i bought it.
OS: Win7(and 10)

Here are the things i have tried:
The first thing i'w tried yesterday is to move the music folder to the SSD.
Tried another motherboard.
Tried diffirent ram. Tried with a random pair of 4x2GB planks.
Tried a diffirent power block. Tried a 450W Chieftec.
Stress tests to try and localyze the source of the problem. AIDA64 stress test(even tried it with the game running). Tried Linx(cant say that the 30min full ram realtime prio was enough). I'w even tried loading AIDA's ram stress test to grab hold of the full ram and launching the game after(in order to force it to ram up in pagesys... if it works that way).
Tried monitoring overheating and voltages.
Tried diffirent games. Tried the latest DOOM(for example).

Nothing of this game me any clues on what could be wrong.

As the system doesnt go to BSOD, there is no dump file or system journal crash statement.

For now i simply switched to foobar(i'm really out of ideas).

Does the problem happens in win 7 and win 10 or only on win 7?
- Run a System File Check on a cmd window: sfc /scannow
- Schedule a disk check on a cmd window: chkdsk C: /f and chkdsk D: /f

You mentioned dead blocks. What do you mean?

This happens on both 7 and 10 windowses.
I'd go for a system check, but the problem continues for more than a year, plus if sticking to the nonSSD harddrive, i'd say i'w checked that one when i copied all of the music to the SSD drive, leaving the first HDD without usage for the test period.

Just a phrase i'w caught on microsofts tech forums(the topic was on something similar, that was fixed with a hotfix...tried that already)
