So let me get this straight, after showing the windows logo it goes to black? Does your system have an integrated GPU? Because if it does, windows might have switched to that one as the main display and so your screen connected to the discrete GPU is black. I've had this happen to myself and the symptoms were the same, the screen wouldn't be completely off (standby) but would display black or some lines left over from the booting process. If this is the case, what I would do would be to either connect the monitor to the Mobo gpu (integrated) and see if something shows up or disable the integrated gpu from safe mode , or when the drivers are uninstalled.(right click computer>manage>Devices>display adapters)
2nd: If that is not your problem, the mom.exe is from the AMD drivers and it means that they are not correctly uninstalled. With your drivers uninstalled google driver sweeper, select ATI, and clean everything that shows up (be careful if your Mobo has AMD chipset... I would recommend uninstalling those as well for the time being and then do the cleaning with driver sweeper. Then reboot (the mom.exe error shouldn't pop up any more) and proceed to reinstall the latest drivers for chipset+GPU.
If that doesn't work, and you don't have an integrated GPU then I am not sure, it could be a number of things, from faulty GPU (it can work with default drivers and not with AMD ones because the AMD ones try to access more things on the GPU) or a bad windows install (from viruses/antivirus deleting what it shouldn't)
I hope this helps
