Hello vaath,
 
What was the original issue with your corsair power supply? was it similar to this one your experiencing?

It could be a video card issue instead, do you have onboard video? If so, try using that to troubleshoot.

Hi, my corsair power supply hx1050 was giving me trouble, randomly shut off. Ordered an EVGA Supernova 850 G3. Well after trying cables, tried every combination or cable and such I had to send back to Amazon. Anyways I reinstalled the old one and no trouble yet. But that isn't the issue.
 
Everything boots fine, got into windows. All was well, but the video kept turning black, 5 or so seconds, black again in a loop. So my first though, use ddu, wipe the drivers. Here's where I got lost, not once did it black screen in safe mode. So I boot into windows, install only the driver, no geforce experience or junk. Reboot, black screens. So i just thought lets see if it might be a driver issue or something. I boot up and with no video drivers, start surfing the web. Not one black screen, multiple drivers all do the black screen.
 
These forums have always helped in the past, i ask the guru's for help!
 
Have a great day!
 

Generally speaking if the GPU operates in VGA mode without the driver loaded but enters a crash loop when using using the 3D accelerated display drivers, the GPU is faulty.

Same issue here but only after installing new drivers.

I dunno if it means anything, I completly spaced out when doing the trouble.I am attaching a link of what I see on bootup at the bottom.  Ya, dummy me.
 
Next I plan on trying the onboard video card, see how that goes. I know little but if it was a cable wouldn't I have had trouble when I first installed a year ago? Same video card, same monitor.
 
As always I really do appreciate the help :)   havgood day :)
 
 Sorry I messed up, haven't really figured out attached photo's LOL
 
 

ahh ok, you mentioned cables, i need atleast a quality hdmi for the integrated any other machines i need to test where can i got a not to expensive expensive, good  cable If it works with integrated then it is either the video card or the monitor, or ports right? With the HDMI I can test it on  the integrated, video card , and laptop.
 
Sorry I am acting a little "slow" didn't sleep well.
 
Sajin seems really good with any  cable suggestions :)
 
Thank you sajin
 
 
 

Sorry Sajin, 
 
I completley messed up what i saying sorry about that.   I do not have a HDMI after scouring the the house.
 
I chose to go HDMI as it lets me try the cable on both the integrated,desktop card, laptop.
 
Hope I am not driving you crazy, your help is greatly appreciated.
 
Also, no idea if this helps you but the monitor is a Dell U3415W
 

So let it be written, so let be done :)
 
Again, you all have been amazing! Soon as I get the cable I will update!
 
 

Glad you stuck with me Sajin.
 
As promised I have an update, gone an hour with no black screens, gonna try out games in a few. Drivers are loaded up with no signs of issue. I am using the HDMI cable you picked out for me. I had previously tried all 3 DP ports on the video card. Leads me to a bad DP port on the monitor maybe? TBH I am just fine with HDMI if I am stuck with it. So I guess there really might be nothing wrong with the video card itself?
 
Thanks Sajin!
