980ti FTW system freeze after few minutes (I messed with PrecisionX)

[DesiPower]

So I was messing around with the PrecisionX settings and screen went blank and the system froze, keyboard shortcuts wont turnoff restart or sleep the box. If I hard boot it, it boots up fine but then after a few minutes it crashes again. I have a EVGA FTW and SC on SLI

I can try uninstalling the drivers maybe even DDU but since the system crashes, it does not give me enough time. I has unplugged the power on one card and now only running just FTW but still same problem.
I guess the only option left is to remove both cards and use onboard display, then reinstall everything? any quicker way out? any way to reset the cards or do anything else within the 1 or 2 minutes I get between system boot and freeze?

Have you tried booting into safe mode and uninstalling the drivers there?

I left it on for a long time and it the PC un-froze, i was able to shut down using shortcut keys, once it came back up it blinking every few seconds, I think I will be able to un-re-install everything now... lets see how it goes...

I had to take both the cards out, use on-board GPU and uninstall everything then put them back in, everything's back to working condition now. Ran a short stress test with 3Dmark and everything looks fine.
