GPU error 43 after installed iDisplay

[nut1414]

I don't know why this happen when i installed iDisplay, This have happen to me 3 times now and each time I have to reinstalling windows is there an alternate solution to fix this?

 

I also uninstalled iDisplay but it does not fix the problem

 

Pc spec:

Intel core i5 4460

XFX 750 Watt PSU

2 Harddrive

Nvidia GT 640 (GDDR5 OEM)

 

 

UPDATE: I have already tried : Uninstall driver and reinstall , upgrade windows 10 -> windows 10

probably because iDisplay is a very crappy, unstable piece of software. i reccomend staying away from it in the future.

as for now, i have no idea how to fix it other than reinstalling windows.
