A few months back my PC started to weirdly crash to a black screen. It actually looked like it was still working for some time with a black screen and no way to get the screen to turn on again. This kind of crash could happen one minute after start up or a few hours after start up. It drove me crazy.
I also tried some programs which will check and repair any software/driver issues. It did not help until one week ago where Restoro identified ICUE as a malware and just dumped part of it. the black screen crashes went away....... After I re-installed ICUE the same black screen crashes happened again.
So three days ago I did a clean uninstall of ICUE - and now my PC is running since 3 days without a single black screen crash.
Ok, I have a quite old system (i7-4930K, ASUS Sabertooth X79 MB) but something is definitely wrong with ICUE. So if you have a similar problem (PC just turns the screen black and the only way out is a restart) and you have ICUE installed ==> just do a clean uninstall of ICUE.
I love the stuff from Corsair (my first choice for power supplies and AIO) but their software often does not work or gives awkward side effects.
