So there i was playing arma 3 on my system then all of the sudden my pc black screens and shuts itself down(crashed). So at first I'm thinking it over heated and i let it sit over night and out a big fan on it with the side panel off. I power it on and get a boot device led and no video on the monitor (Black screen) Then i started diagnosing,

*tested monitor (works fine)
*Took out the ram
*rewired
*took out gpu and started on dedicated graphics (worked)
*put in new gpu and it worked

The current GPU is lit up fine and fan runs fine as well
So is my mobo have a problem or the gpu?


PC specs:
i7 3770
GTX titan
asus sabertooth z87
PSU: hx1050
16g ram vengence
 
Solution
If you put in a new GPU and it was fine then you are probably down to the Titan or the power cables feeding the Titan (are they all tight, are their others you can try), or the PSU no longer putting out enough power

I am going to try the titan at a friends on set up tomorrow, im thinking it may be a power supply issue bc i dont understand how the titan could just die out of no where, i know it wasnt a overheating problem so i could see a psu problem.
