I've recelntly started getting these annoying BSODs, I searched into it with no luck

; after finally getting WinDbg to work

i maneged to analyse minidumps, it indicated Bug codes 0x124 with process name = system, searching for this, it seems its a hardware issue

, i've tested the RAM & Hard disk everything is ok, i also had my
drivers updated, and all windows updates installed. I dont know whats the problem! These BSODs happen randomly, i can regenerate this problem by copying large files from an external hard disk, appritiating any help.
