Hey guys , idk if its a problem of my graphic card or something else since i can still hear the skype and talk with my friends wh ile it happens
so the screen freezes for 1 second then it turns off , after that if im trying to move my friends tell me that my character doesnt move , (means the pc it self doesnt respone or soemthing) but i can still talk with them through skype ! and to fix that i have to restart my pc.
it ussualy happens on big mmo games but today it happened on MOBA games like heroes of the storm / league of legends which it never happened before .
Anyone knows where the problem might be ?
i have r9 200 series , 280x probably (dunno how to check the numbers in this series)
100% its not an overheat problem , once i thought it was but then i saw that it happened when the pc was on 36 degrees on some game and ussualy when my fans arent turn on my gpu reaches 75 degrees and doesnt turn off .
Sorry if its hard to understand me , its my first post in here and my english isnt good
