[nota]

sorry but no onboard video output on this m/b so can't do that

I do have two video cards both the same but missing the SLI bridge connection
so only use one card at a time
I have tryed switching out the cards and in different pciE 16 slots also [have 2 on the m/b]
updated video drivers ect

memory stress tested in w7 passed ok some time ago when problems began

over all w10 is working fine after overnite d/l
and no crashes today other then the performance rating test crash
even was able to play a HD video in full screen that I could not do before in w7

the performance rating is just a way to see if it will crash
really do not need it or care about it
but maybe a clue to why it crashed

thanks for your help
will post again if I get problems outside the performance rating crash in w10
