Big problem - GTX 980 Ti cannot render anything.

[miel2000]

so about a month ago i built my pc, i was perfectly happy until 2 weeks ago. for some reason now when i try to render video games it crashes,and i have to turn it off completely. sometimes it does work however and when it does it works perfectly well with no drops in fps. when it crashes the music keeps going and my display shows "OUT OF RANGE".Because it sometimes does work i have reason to believe the problem lies with the driver. olso the problem seems to have shown up right after i updated them.

what i have tried to fix this problem
-reinstalled drivers
-Uninstalled drivers using DDU and then reinstalling the newest one
-Uninstalled drivers using DDU then installed older one
-reinstalled only the neccesary drivers(Physx,audio,Graphics)
-reinstalled windows 10
-uninstalled windows 10, completely formatted hhd , then installed windows 8,1
-removed graphics card, cleaned it and the port , then put it back.
-reinstalled video games
-reinstalled all of my drivers ( not just gpu)
-Lower clockspeed
-Lower resolution

unfortunately none of these things have worked, and this problem basically makes such an expensive gpu useless.

parts
-Asus B85M-E motherboard
-Intel i5 4690k with the cooler that came with it.
-8gb hyperX fury 1600 ram
-Gigabyte 980 Ti reference cooler
-630 watt thermaltake Smart Se power suply

If anyone has this problem and knows how to fix it please inform me, thank you.

It maybe your power supply - the recommended PSU is 600W so your model has very little headroom left.

I tried setting the power levels down in oc guru and msi afterburner to 60% , worked for 2 days then i had the same error

Does the resolution setting in the game match the native resolution of your monitor?

yes it does , and i've also tried lowering the resolution

It might be MSI Afterburner - it's known to have issues with some games.

Also, reducing the voltages with Afterburner won't help as the card will look at what the incoming voltages are from the PCI slot/8-pin connectors. I've had a few instances in the past of cards not working because the 12V that supplies the card wasn't up to the job.

Other than than I'm out of ideas.
