@bp9801 the videocard have vga conector(is direct connect)

i think is voltage+clock low values for card boot .

after passing windows welcome screen the monitor have signal.in games not have crash or bsod is comportament normal

this problem is only start pc or restart.

but happened afew times to no pass in windows:(

1 in my room have(with window open cool) 18 c and open pc card no signal or delay to monitor
2 in my room have 25C(normal temp) and start msi kombustor for 10 min card have 61C ( is ok) but stop kombustor and restart pc the monitor not have signal or delay from card.
3.in my room have normal temperature 25 and open kombustor run for 10 min and close pc WITH 10 MIN PAUSE AND OPEN AGAIN PC THE MONITOR HAVE SIGNAL GOOD AND WORK
mention:all temp CPU psu and ram(put finger)and hwinfo is normal
