Hello everyone. I have ran into an infuriating problem that I cannot seem to find a solution to. I recently bought a new monitor that displays at 1920 X 1080. Shortly after using this monitor I started to notice my GTX 760 video card start acting weird. Sometimes my screen would randomly go black and I was get a message about some sort of driver being recovered? So then tonight, out of no where, my entire PC just powers off for no reason. I try and start it up and the fan on my video card goes to 100% speed but my monitor does not detect anything. I plugged my monitor directly in my motherboard and all is fine, aside from my graphics card acting like it is fighting a forest fire.

Could it possibly be due to my power supply? I really hope it is, I've only had this video card for almost 2 years. Could my GTX760 be shot? Any ideas?

Here is a Youtube clip of an issue VERY similar to mine. Any help would be very much appreciated.

What power supply is it and how old? When graphics cards act up, more often than not it's the PSU, so you are on the right track with your thinking. Going to higher resolution to make the graphics card work harder may have pushed the PSU over its limits.

I am using a corsair cx600. My question is that why would the video card still be spinning out if control when I power up and my monitor is hooked up to my mother board?

Have you cleaned and inspected your heatsink and thermal compund on your GTX 760? It might be running hot.

As far as the CX...

It's summer time, and often penny pinchers who cheaped out on a power supply will also cheap out on good air conditioning.

The problem with the CX line is that Channel Well builds these low cost units with the cheapest Chinese capacitors available (CapXon). These capacitors do not like to be warm at all. Once they get to 35-40C they tend to stop filtering ripple properly. These ripples get fed right to the graphics card and cause instability. This can make your GPU run hotter, and cause things like artifacts and driver crashes.

I see this problem here many times per week, but more often in the summer.

So, first clean your case filters and fans, GPU heatsink. It's probably out of warranty, so take it apart and put new thermal grease on it too. You might as well clean and inspect your CPU heatsink too while you are in there.

If the problem persists, try blowing out your PSU with compressed air. I do not advise taking a PSU apart unless you are a real electronics technician. If it still gives you problems, then get a new PSU.

Reinstall Windows (I recommend Windows 8.1 for absolute stability) and try installing 1 year old GPU drivers. Recent drivers for Nvidia have either been generally buggy or have reduced Kepler GPUs performance to make Maxwell GPUs look better in benchmarks.
