Computer keeps Crashing with 2 beeps

[Cruesifixx]

I have been having problems with crashing on my pc here lately when I play certain games. For an example when i play fortnite I can play a game or 2 and then it would suddenly crash. The screen will go blank and I will receive 2 beebs when the screen comes back on. Anyone know why this is happening?
