You've got a mini space heater inside that case.
Your pushing close to 500w with the cpu and gpu.
Remove the side panel.
Point a small fan at the innards.
So with the help of a more tech-savvy friend I put together my current desktop in early November, and after some time I realized it will freeze up randomly while I'm playing games(Black Desert Online, Dota 2, Space Engineers).
On average once every few days, the screen will freeze, the sound stops, and the keyboard becomes unresponsive. The only way to get past this is to hold down the power button.

I'm not really sure what the issue is, so here I am, asking all of you for assistance.
