Display Crash and Computer Freeze

Lately, when I play games for about 15-30 minutes, my screen shuts off and my computer freezes. Occasionally the sound will loop or it will keep playing sounds with no response.

This has only been happening the past few days and I can't figure it out.

Can anyone help me?

Between the time I started the game and the time my computer crashed, I got these errors.

Tried reinstalling DirectX, no go.

No ideas at all? It just randomly up and started crashing like this whenever I play games.
