im using evga gtx 770 sc acx gpu boost 2.0
my monitor turns off suddenly while gaming and gpu rpm hits 100 but heats are fine 50c-40c
happen on direct x 9 10
while playing nfs hot pursuit 2010 monitor turnoff gpu rpm hits 100 within 30 min
gta v some time after the loading screen some time after 30-60-min
what is causing this issue?

after clean install of graphic drivers seems to work for a few hours and then crashed

had these dump file called kernel watchdog in crash dump

Various references suggest the driver timed out, but unless you know how to interpret those BCP hex values it isn't going to say much. On the other hand, you can do some testing. Does this occur only on this game? If so, it would seem to be a driver interaction with the game (this wouldn't be surprising). If this occurs under other graphics loads for multiple applications (it would be really great if you found some sort of diagnostic program which loads the video system...or at least stresses it), e.g., other games, perhaps it is hardware. It is even possible some other driver has caused this driver to delay and video is just a symptom of something else going bad. Basically, you need more data.

these seems like power failure when i remove the 8pin and 6pin from gpu the gpu fan hits 100 when i plug in its normal so i think this is the power issue so i think reduce oc through msi after burner and nvidia debug mode works for a while no crash on desktop only on direct x 9-11 running program all the games and 3d application. this issue could be the SC voltage also
but i can watch movies and browse internet everything seems normal

If this fails with the power connector off, then yes, that connector is mandatory, not optional. Having a marginal power supply right at the required limits would be similar. Note that under heavy loads more heat is generated, and as heat goes up, required power delivery voltage also goes up (or at least the minimum voltage for stable operation approaches the existing deliverable power...when available power and required power meet it crashes with even the slightest spike in power usage).
