Question PC will be forzen the first time i played the game in oneday

[mikelearnpop]

After the computer is turned on, in the process of playing a game for the first time in oneday, such as LOL or OW,the screen will suddenly stuck(frozen) ., press nothing to respond. If you restart, the computer will have 5long beeps. I usually replug in the dvi line of the monitor, then it could be restarted . But the problem still arises the next day when you play the game for the first time.
If i don't play games , the PC is always ok .
