Ok so my computer screen will go black every so often, more so when i'm gaming, and then comes back. During that time all sound is gone even though my sound is external through logitech 5.1 speakers. I've tried replacing the hdmi cord with a brand new one, I bought a new monitor, tried multiple solutions online but nothing. Recently i turned on my ps3/p34 which are connected to a different screen but right beside it are doing the same thing now, both plugged into different surge protectors.. is the problem the house?

My specs are:
Intel Core i7 4790K
Corsair H60 Liquid Cooling
MSI Z97 Gaming 3
HyperX Fury 16GB
2x8GB DDR3-1866
MSI GeForce GTX 970
Kingston HyperX Fury 120GB SSD
Seagate Barracuda 1TB
Corsair CX750M 750W PSU
Windows 7
