I woke up this morning to a bios screen on my computer stating an unsafe voltages were tripped by the bios. I continue to start up windows and after I log in I just get a blank colored screen sometimes white, black, pinkish. I reboot into safe mode fine and uninstall the video drivers and am able to reboot into windows.
 
How do I check what has gone bad?

I tried another video cable and I got to the desktop before the screen going out.
 
Windows 7
Intel core i7-4790k CPU
Asus Maximus vii hero
EVGA GeForce GTX 980 Ti ACX SC+ ACX 2.0+ Graphics Card with Backplate 06G-P4-4995-KR
Cosair TX650M power supply
 
I have windows on its own drive for easy installs, so I have that to try after I go through your list.

Well now with video card drivers installed it usually goes to a black screen after I log into windows. I guess I will try to format and reinstall a newer windows.

Sometimes it works and sometimes it comes up as a random color screen that I cant get past now. I had installed the GeForce experience and it started acting up again. I reverted the windows 10 install before anything was installed and was able to get to the desktop again.

The fans run on boot up and then don't spin anymore.

Most likely will be able to test it in another computer in the morning.
 
I was able to control the fans with precision x, so they seem fine.

If the same issue occurs in another pc the card has a problem and will need to be rma'd if still under warranty.

What would be a good way to test this in another computer that doesn't really have games? Just run a video diag software? I guess I can check before hand on something that also crashes.

 when the card is in ''safe mode''   it running on low power ''safe''  to insure boot .  when you add the driver  the driver  kicks in the cards full power states / features  and that's where you see it fail as you say. 
 
now could be a psu issue feeding the card  , but you say the 970 seems to work as expected  so  far  on that same psu .  for me here  99% of the time if a card fails to take the driver  or fails to work under the installed driver  but will display under safe  mode   its something failed in the card . 
 
like said its best to test that card in another strong gaming rig or a build that can take the card / compatible for these cards   [ good psu , real motherboard , ect . not a prebuilt like a HP or dell type]
 
good luck

Why do you have windows update the drivers for you?
You should disable windows installing any drivers except the windows updates.
Also, do NOT install Nvidia experience, or anything except the drivers  and physx (unless you have speakers in your monitor, and you need the sound drivers from nvidia to use them).
I am surprised that none said to disable that, and try an older driver. Nvidia has not been very good with their drivers as of late.
Go back to 388.00 drivers and check and see if it works with the 980TI before sending it in and having them send it right back to you.
If it still doesnt work, yeah, you have the evga 900 series high end video card problems that a lot of other users have (ie, need to rma).
:(

 
''You should disable windows installing any drivers except the windows updates''
ya.
if you got that malware service  called win-10  you best .  with it you do as Microsoft want not as you want  even turned off I could not trust it as far as I could throw it  / I'd never use it   and have to hate your guts to even think of recommending it  to be used  [lol ]
