Having this frustrating experience where both of my simcity games won't load, my tv (which i use as a monitor) just goes to no signal, may i add that i've done most of the common workarounds on both my pc and laptop but still both do not work. The thing that really gets me is that both games used to work perfectly fine on both laptop and pc 
so why should it work fine one day and then just stop working....my pc will happily run the sims 4 (it's not the best pc at all but like i say they used to work and will happily play sims 4, skyrim etc). I'm praying that i'm overlooking something ridiculous but i fear i'm not as i've tried most of the "fixes" i'd honestly rather play sim city 4 but at this point i want to get any working....if not i'll be switching to cities skylines as i just want to build some cities. Simcity 4 is the vanilla edition so no RH etc and is a disc copy. If someone can help me out i'll be forever grateful, just really wanna play sim city and i've spent all day trying to "fix" them. If there is any other information i can give then just ask away....i'd post my pc's spec an all but I cba + most people would probs say your pc is awful and i need to upgrade this and that but honestly it worked a while ago and all of a sudden i cant play either game on it so i know the game runs fine but for some reason it just won't load it up anymore. If anybody can help me out here i'd be massively grateful. Both my PC and Laptop are windows 7 64bit
Here's some footage i've put on youtube so people can see what happens.
