Custom Resolution Utility (CRU)

[agggile]

I've come across a problem after an attempt to create a profile using CRU on my old computer.
It's running a GT520 and the monitor is Dell E248WFP.

After an unsuccessful attempt, I decided to run reset-all to go back to where I was.
Now, for some reason I can't run Windows without safe mode or the monitor enters sleep immediately.
CRU is reporting "No displays in the registry". Same for reset all.

I've tried re-enabing the GT, updating drivers and re-installing drivers.

What could be wrong?

edit: I've now tried to use multiple displays, always ending up with the same result (sleep). Tested both DVI and VGA.

edit 2: I've now run a System Restore with no avail. It's getting spooky now.

edit 3: After some fiddling, I finally got out of the Safe Mode dependency by disabling the GT. I tried this before and it didn't work, but for some reason it works now. Going to attempt a fresh driver install once again now that I'm out of Safe Mode, which shouldn't even make a difference, but right now nothing makes sense.

edit 4: After a clean driver install (had not selected this option before) in normal mode, I -still- end up with the monitor entering power saving mode after the windows logo from startup has vanished. Using a display that supports 75hz at native resolution, and if I remember correct, the change I made with CRU was 1920x1080 @ 59.994 -> 1920x1080 @ 60. I did this so I could simply test how the program works, I hadn't used it before. Yet, I don't understand how the CRU-made modifications could still be in play since I've done just about everything that has to do with the card/display.
