Dying GPU or PSU Help??

[Shadowkuo]

I just recently started having issues when I open games, browsing the web and stuff is ok, but as soon as the game opens my screens go black. I have troubleshooted the issue but not sure if its the GPU or PSU. If I use HDMI + Display Port = black screens. Just Display Port = black screen, Just HDMI = black screen, but if I use the DVI port only games run fine and no black screen.

GPU is R9 290X Lightning. CPU is i7-4790K. (Nothing O/C). Moba is Asus Maximus Formula VII. 32GB DDR3 1333Mhz Corsair Dominator. PSU is Corsair RM850X. 

 

I have completely redone windows, removed all old drivers and got new ones. Tried a CMOS clear.

if you have issues with HDMI and or Displayport but not DVI, i'd say it's gotta be the GPU.. power usage is the same for all the ports, so the PSU should not be suspect.

Can you try with a different GPU? maybe a friend can lend you one?
