Microsoft Windows 10 (64-bit)

I have a z840 dual xeon , it will be working fine but when I render google earth or play a video, screen will go black , fan will slow down then it will beep and red flash coming from the computer itself,  it beeps 6 short beeps with a pause then repeats the 6 short beeps again, does this 5 times. Each time about a 2 second pause in between. Then it just flashes, but the system continues running with no display. I can reset the system and it comes back just fine, but does the same thing over and over. I run an older nividia quadro 4000, have uninstalled and reinstalled the updated drivers, but still does the same thing. I am not sure if it is the gpu or something else. Anyone have any ideas? All my cpu core temps are low but the main fans scream a lot.

This seems to be a memory problem 

 

The Diagnostic LED blinks red 5 times and the system beeps 5 times (once per second), then a 2-second pause follows:

This indicates a pre-video memory error.

To resolve the issue, complete the following steps:

1) Ensure that the memory modules are loaded correctly.

2) Reseat the memory modules.

3) Replace the memory modules one at a time to find the faulty module.

 

 

Unplug from wall, remove  side panel, touch finger to metal case before touching any inside components.  Use an air duster to remove dust since you got the case open.  Dust out power supply and video card too.
