Random BSOD 0x124 occurences

Hello, I've been plagued by a BSOD issue for quite a while already and ultimately I have failed to fix it by myself so I would like to ask for some help.

As a sort of user-gathered information its probably important for me to mention the following things:

1) the BSOD always gives the same 0x124 error;
2) it started right after i bought the new graphic card in november;
2.1) despite it might seem obvious that it could be caused by a faulty graphic card I've ran a few tests using Furmark, OCCT and some other software to check it and during those tests i havent gotten any bsod;
3) I have reinstalled windows recently as an attempt to fix bsod as well;
4) BSOD often occurs upon the Windows launch, sometimes during the greeting screen, sometimes a half minute after desktop loads;
5) less often BSOD occurs while im gaming or when PC is simply idling, those BSODs seem completely random and unrelated to the current load on the system but I might be wrong;
6) PC is clean from dust and it doesnt seem to be the heat issue, since BSOD often occurs on low temperatures;
7) Sometimes there are several days between BSODs and sometimes it happens 2 or 3 times in a row upon the system start as described in point 4).

Well, thats all what I can recall about my problem. Sorry if the text is huge I just wanted the post to be as thorough as possible.
