About a while back I did a clean install from Windows 8 to 8.1(through CD), I then downloaded some programs such as Skype, Reflector, osu! and some games such as CS:GO and TF2. When I ran them they all instantly crashed (except for Skype which crashes when I call or change a picture)! About a week ago I reset my computer back to default, installed osu! and tested it out and it worked. So then I installed 8.1 again and installed them and they crashed! Yesterday I discovered that if I boot into safe mode they work! Anyone have any solutions to make them work normally?
