alrite just to share with u guys here. i recently assemble whole new pc myself with the help of pc shop... from monitor, pc till keyboard and mouse. so once done, i bring my pc home.... test it with benchmark app... seems fine. no issue.
since i bought a new GPU so i run some game to see if any issue or not. true enuv, it went bsod... or crashing like after 10-20 minutes... initially i thought is overheat.. either way i install my new fan. it doesn't solve the issue end up i bring my pc to the shop and ask them test it.
they ran more extensive benchmark app through day and nite but didn't catch the issue.... then i ask them run the game and they manage to finish it some more.... so they said flashed my bios so it should be fine. i brought it back and test it. same issue and i download low end game also got bsod. end up i bring it back again.... they willing to swap my gpu n psu since its bsod with event 41. they said usually is psu issue or gpu because i got bsod during gameplay....
it doesn't end there.. cause after change i still face with crashes.... with ntdll.dll or event 41....
after some googling... i reinstall window 10 and retry...same issue... and some suggested to test memory....so i ran a memtest and found whole bunch or errors....... went back swap memory card and tada...all error gone.....
so just in case anyone face similar issue, probably do a memtest

confirmed not driver issue... first thing after setup the hardware sure is install driver and get it updated. however memory issue will not lie with those simple memtest...
