sudden crash while playing dota 2

[Neruu]

So I just build a new gaming pc with these spec
ryzen 1700
asus b350-plus
corsair lpx 16gb 3200mhz
evga sc 1070 8gb
wd caviar blue 1 tb
samsung evo 850 250gb)
corsair tx 650w
and apparently my pc just suddenly crash randomly every time I was playing dota 2 and only this one game (I have no problem playing other games such as csgo, elder scroll, skyrim, etc.)

Idk if the problem lies within my software or hardware but everytime it crashed, my pc is actually still running (only my stock cooler led went off) but on my monitor, there's no signal inputed
I have to push the restart button to reset my pc and goes back into the game (I can still play because usually it happens only 2 or 3 times/game)

appreciate if anyone can help :3 thanks

how do i check if i ran it on vulkan or not?
yeah, i played csgo, eso, left 4 dead, pubg but every other games work fine

i just checked my dota2 dlc and i haven't installed either opengl support for windows or vulkan support
should i install them?

u just check the DLC tick box and it will start downloading. https://www.facebook.com/notes/wykrhm-reddy/setting-up-dota-2-with-vulkan/1097489820273895/ read this to set up vulkan for dota. dunno how much it can help it since we havent identified the problem yet.

in the end i solved it by reinstalling dota 2 by download (before i just copied it from my old pc), and works fine now ^^
