No display on television and monitor?

[Silentkiller424]

My computer is connected to an led television via HDMI canble and to a monitor via DVI cable. I have a gtx 970 which is about a year old.
My problem is that i get no display on neither the monitor nor the television some times. I have to restart the pc using the power button and then I get display normally.
Sometimes i get just a black screen on my monitor and nothing on my tv which after restarting 2-3 times works normally.
What could be the problem here ? Is it a faulty graphics card? My drivers are updated and all the games work fine. I also repaired the pc using the windows repair os tool by burning a disk but still the problem persists.

I supposed it could be the power supply. What model/wattage are you running? Using windows 10? Kinda sounds like a Windows issue too. Not sure. Well see what others have to say.

I'm using a 550w smps gold standard and running on windows 7

Hmm. Haven't heard of that power supply. Maybe that is the issue. When a PC boots, it uses quite a bit of power initially. I recommend Seasonic power supplies, a 550w unit from them should be sufficient. Be sure to get a Haswell certified one if that is the cpu you are running.

The computer boots fine (the fans light up and all) but there is either no display or just a black screen on the monitor.

Sure, I wonder if the card isn't getting enough amperage on boot. Have you loaded the system with 3dmark loops or something to that affect? Furmark is a good benchmark for testing gpus and how the psu does too.

Im using furmark right now at 1080p 8x anti aliasing but im not pretty sure how to use it? It seems to be working fine, how do i deduce from it what the problem is? I am getting 20 fps right now and 249 average fps.

Sounds like the gpu is throttling if it is at 20 fps (due to heat or lack of power). Watch the temps and clocks to see what happens. Furmark just runs a fury donut on the screen to load up the gpu to the max.
