Dual monitor works, then they both go sleep and seems no response from GPU?

I'm running a 1920 x 1080 and the other one is 1600 x 900, I'm trying to make it work for educational purpose but it fails.
I have an r9 290x
12 GB ram 8350 processor.
It usually lasts about 10-15minutes sometimes way less and they both die. I try to test to see if the computer itself was functional maybe a gpu fail or something or the monitors use too much resources but it didn't work. The computer was completely not responsive, no noise can be heard I can't even restart using hot key on my keyboard. I can't do nothing even power button doesn't work I have to hold it. Once I hold it it turns back on and works normally. If I have one monitor disabled this doesn't happen including playing top spec games. I'm running windows 8.1.

There used to be a time where GPU reviews checked power consumption scaling with the number of displays connected to them and back then, GPUs often consumed 5-10W more per extra display.

The other thing I can think of is clocking issues: on my HD5770, if I mess around with clocks with two or more displays attached, PowerTune often ends up setting the GPU/memory clocks far too low to support the multiple output streams, which causes display corruption on the secondary/tertiary displays and sometimes cause the GPU/drivers to crash. The same thing happens when software starts using a video overlay: the GPU drops to 2D/idle clocks...


Not instantly, like depends sometimes about 10minutes later.

That's what I was thinking, but he said it only happens with 2 monitors plugged in, not one. I don't see two monitors affecting heat in any way, especially since gaming is on one monitor.
 


I was thinking the same, I use 1 monitor while gaming, the other one is off, this can simply occur with me being on the browser and browsing the internet.
