It only started happening after i did a full system wipe and used windows' feature of removing everything and starting from the beginning. i can game from any were from 10 min to 5 hours. it has also happened while i was browsing the web on youtube while the system wasn't under stress at all. when it crashes all it does is the sound playing(any sound at the time of crash) stutters rapidly. about half a second of the sound stuttering, my screen goes black and my computer powers down, and turns back on. even after all that the computer boots up as if nothing happened. please help me fix this as ive checked everywere and i havent found a clue as to what it may be. thank you.
