I used Asus GPU Tweak to overclock my R9 290 and after I hit apply the screen went completely blank. I've restarted several times, each time I get as far as logging into my account then the screen goes blank. I can log in fine in safe mode.

What I've done so far - tried to uninstall GPU Tweak, but I kept getting windows installer service error 1719, so I manually removed the registry keys and ran Ccleaner. I tried to download and reinstall GPU Tweak, but running the installer gives me error 1607: Unable to install InstallShield Scripting Runtime

System Specs:
Windows 7 Ultimate 64-bit
i5 2500k @3.3 GHz
8GB RAM
Asus Radeon R9 290
Corsair HX1000W

Unfortunately I cannot provide a dxdiag (everything under display is marked n/a, I'm assuming because I'm in safe mode?)

Any help would be greatly appreciated, I'm itching to get back to Titanfall ;)

Edit: being a fool, I don't have any system restore images saved, or I'd just do that. And my windows install disc has been lost for years :(
