Z420

Hello,

First of all sorry for my bad English 

I have Z420 workstation with Intel(R) Xeon(R) CPU E5-1620 0 @ 3.60GHz, RX 570 graphic card and installed 4 hard disks 

2 SSD and 2 HDD 

32 GB = 1 16GB + 2 8GB

when I'm playing games especially high games which using the whole PC hardware most of times 

the screen turns into black and power still on but looks like the PC shutdown and also the power button turn into red then flashing with 6 beeps until I press on it one time then the whole PC shutdown instantly 

I don't know what's the problem I just want to know what is that problem to solve it  if it's a software one or hardware

so what's causes ?
