Limited access to my computer upon startup

Alright, so right now I am operating in Safe Mode with Networking, despite my computer working perfectly fine a few hours ago. The first problem I noticed when I started up was my network was saying that it wasn't connected(this was in the toolbar), although for some reason I could open Chrome and Firefox. So of course I tried to right click on the icon to open Network and Sharing, but no pop-up came up. So next I tried going through Start>Control Panel when I found out that Control Panel wouldn't open. So I restarted my computer to see if something didn't load correctly, etc.. Same problems occurred so I did some research for solutions to similar problems and some of the options I found were to go to Start and search for "Services." This was when I found out that I couldn't type in the Start menu search bar. I tried another option through Run(I had to use Win + R) and then typing "sfc /scannow" and then pressing enter. A console popped up just long enough for me to realize that it actually ran my command before it disappeared and did nothing else. By this time I could right click on the network connection icon in the toolbar, and I tried to run troubleshooter by it gave me an error with something to the extent of "could not open remotely" or something like that. I restarted my computer again, this time in Safe Mode, but the same problems with not being connected to a network, and not being able to run hardly any programs or applications occurred again. I restarted another time in Safe Mode with Networking and here I am. The connection problems are gone and I can run applications again, but if I am not in this specific Safe Mode the problems still occur. So all I know right now is the problem is not within the default programs. I'm impressed if you've made it to the end of this and I thank you in advance for any help you can give! I need all I can get :)
